Arundina graminifolia - Bamboo Orchid

 
        PLANT PROFILE

   Arundina graminifolia is species of terrestial tropical orchid, unique for its growth habit. It create a clump of single, tall, straight and unbranched stems, raised perpendicularly up with a beautiful orchid flowers on its tips. It is native to tropical and subtropical region of Asia, from Nepal, India, Sri Lanka, southern China, through Southeast Asia to Ryukyu Islands and Tahiti. And has been introduced in many tropical regions around the world, and naturalized in some places in Hawaii, Mexico, Panama, Columbia and South Africa.
   Arundina is highly appreciated for its ornamental value and nowadays even in its native regions, it is more common view in garden cultivation than in wild state. Orchid hunters and medicinal plants gatherers have caused its wild population in many regions do decline to drastically low level. Because although nowadays this plant popularity is mainly about its charm, for many people it is still an important folk medicine. 
   Arundina medicinal properties are esspecially valued in Traditional Dai Medicine, and it is one of the most commonly used medicinal plants in TDM. Traditional Dai Medicine is a medicine system of Dai people, Tai-speaking ethnic groups that lives mainly in southern parts of Yunnan Province of China. This plant is also used as a herbal medicine in India, Bangladesh, Sri Lanka and Southeast Asian countries. And the plant material is obtaned sill mostly from wild state, but sometimes it is also planted in gardens along with other medicinal herbs.

   While in the Western world nowadays orchids are seen almost entirely only as a beautiful flowering ornamentals. In rular areas of tropical and subtropical Asia and Oceania, but also tropical America and Africa, many orchids kinds like Arundina are still impotrant, commonly used folk medicine.
   The name Orchid originated from the Greek word "orchis," which literally means testicles. It was allegedly Theophrastus who first used the word Orchis for name of a particular classified group of plants. The group of plants which flowers structure shows resamblance to look of testicles, and which roots was used as aphrodisiacs, antidepresants and general mind and body tonics. And although most of tropical orchids species differs a lot in their plant structure and growts habits. Many of it shares reputation of possesing the same healing properties as the mediterrean ones, although it was traditionally atributed to it by distant entirely unrelated ethnic cultures.

    Arundina name derived from the Greek word 'arundo' which means reed, and the epithet graminifolia is a combination of words 'gramineus' and 'folius', and means grass-like leaves. But this species was first described in 1825 by David Don in Prodromus Florae Nepalensis as Bletia graminifolia. And only much later in 1910 it was transferred to genus Arundina, by Benedict Hochreutiner in the Bulletin of the New York Botanic Garden.
   Arundina is such a unique kind of orchids, that the genus consist of only two species. Anrudina graminifolia flowers are variable in color and size but it is only recognized as a variations of this one species. But a dwarf form Arundina graminifolia var. revoluta that originates from Indochina and Borneo is such a distinctive plant that it was recently recognized as a seperate species named Arundina caespitosa Aver..
   It was probably this fact of variations in flowers outlook, that lead to big number of scientific Arundina manes given by many different scientists. The names like Arundina affinis Griff.; Arundina bambusifolia [Roxb] Lindley; Arundina chinensis Blume; Arundina densa Lindley; Arundina densiflora Hook. f.; Arundina maculata J.J. Sm.; Arundina speciosa var. sarasinorum Schltr.; Arundina stenopetala Gagnep., are all currently considered to be just a synonyms for Arundina graminifolia. But it is quite likely that in the near future, some another Arundina variety will get separated into new recognised Arundina species, like it was with the case of Arundina caespitosa.

   Bamboo Orchid is an english name for this plant, and it so perfectly describe the plants character, that it has became the most commonly used name for this plant worldwide. Arundina graminifolia is sometimes also called Chinese Arundina or Bird Orchid in english, and here are some of its vernacular names used in other languages : Wen Shang Hai (Dai name), Wah-Thit-Kwa (Myanmar), Ubi Bemban, Phanyar, Orkid Buluh (Malaysia), Hui Laki, Hui Bini, Anggeric Bam, Handjuwang Sapu (Indonesia), Ghasphul (Bangladesh), Ueang Pai, Khaem Dok Kho, Khaem Lueang. (Thailand), Euong Phai (Laos), Lan Say (Vietnam), Zhu Ye Lan, Changgan Lan, Shiyu Lan, Bai Yang Jie (China), Chiau a Hoe (Taiwan), Teet Pindalu (Nepal), Orchidee Bambou (France).
 

          CULTIVATION AND HARVESTING

    Arundina is a genus of evergreen, terrestial orchids, with very characteristic single, unbranched and usually absolutely straight stems, reaching upward at perfectly perpendicular maner, with flowers on its tips. The whole genus comprise of only two species, Arundina graminifolia with stems up to around 2m tall, and dwarf Arundina caespitosa which stems grow just up to around 50 cm height.
   Bamboo Orchid grows naturally in forest edges, open scrub and riverbank tussock on mountain slopes up to 1700m and lowland rain forests. 

   It creates bamboo looking clumps colonies, spreading through its rhizomes, that grows new pseudobulbs, from each always only one stem grows. And so it can be easily propagated threw the clump divison. But it can be also propagated from seeds, stem cuttings, or young plantlets (keiki pseudobulbs) that sometimes it grows on its stems from nodes, usually near the top of the stem. 
   In recent years high demand for Arundina graminifolia on ornamental plants markets, due to its increasing popularity as a interesting element in tropical gardens landscaping. Has brought many big scale plant nurseries into tissue culture multiplication of this orchid. And different techniques of Arundina in vitro propagation was tested for best effectiveness, in agricultural academic centers.
   Arundina likes tropical and subtropical climate, it is highly heat-resistant and can withstand only mild freezes. It is rather well resistant to diseases and pests, although fungal infections and infestations of mealy bugs can happen to it in excessively humid and poor air circulation conditions. And one of the main reasons for its popularity as a ornamental garden plant, is that this pretty, interrestingly unique looking plant is very easy to maintain. For its good look it is only needed to remove its old, dead stems every few months, or remove any weeds if such grows among Arundina stems in its clump area. 
   It loves strong sun and like sandy, loamy and rocky soils, well draind soils. And I even found one source stating that Arundina is also a lithophyte, which means that it can grow on a bare rock, taking all its nutrients only from scarce, accumulated in rock cracks, fallen leaves and dust. It withstand very well even long term droughts, but for good growth it require proper moisture.

   Arundina graminifolia flowers are around 6 cm long, scented and short-lived compare to most of ornamental orchids. The single flower last just for about 4 days, but each stem tip has few (up to 10) flowers, that open all in straight successe manner. That makes the total lasting of flowers on each stem considerably long, and for that reason Arundina is sometimes used as a cutting flowers. Arundina caespitosa flowers are around 4 cm long and each of its stem has just 3 to 5 flowers on its tip. 
   A. graminifolia flowers can appear in a wide range of purple-pink shades, from dark violet with white and with orange middle, to pale pink and white with pale yellow middle. While A. caespitosa flowers are mainly very pale purple-pink with white, and often entirely white with just traces of yellow and purple in the middle. Except for color variations Arundina flowers has also variations in shape characteristics, as particular segments, petals can be more wide or more narow, shorter or longer and more or less curvy. And for that reason many plant nurseries propagate Arundina only in a vegetative way, to preserve original look of particular cultivars, that would be much likely lost in offspring from the seeds.
   In Malaysia, Indonesia and the Philippines, Arundina flowers throughout whole year. But in other regions its flowering period vary a lot. For example, it is said to be during August-June in Tripura, India; April-September in Sikkim, India; June to November in Myanmar; August to March in Thailand.

   All parts of the plant can be harvested throughout whole year. But the stems are best to be used for herbal teas after it is fully developed and hardened, and before it gets old and its leaves starts to turn yellow. Although I haven't found any information about commercial scale plantations of Arundina for harvesting for a plant material to be used as a herb. And it is gathered for medicinal purposes still from wild or grown in herbal gardens. From all the species of orchids used as healing herbs, Arundina is deffinitely the easiest one to grow and harvest. Producing big mass of stems with leaves, that are very easy to cut and dry.
   
 
         CULINARY USES

  Very few sources ever mention that flowers of Arundina are edible, but I was lucky do dig out this information. And like many other edible orchid flowers it has some health benefits (in Malaysia Arundina flowers are being eaten stir-fried, which is said to controll high blood pressure), and also much of decorating value (as used in this Hawaiian Pumpkin-Orchid Soup recipe). But I have to say that Arundina flowers are the most bitter flowers from all edible flowers that I had a chance to try, and therefore hard to enjoy.

   Infusion from fresh chopped stems with leaves of Arundina, can be depend on amount used strongly or mildly bitter (it is the stems that gives bitterness, leaves are not bitter). But even when the infusion is made weak its bitterness is mild, but it is what I call a sharp bitterness. A kind of bitterness that some like me love, while others hate. But weather it is your taste or not, this bitterness is making Arundina tea a great tonic. Esspecially excellent to drink chilled with honey and a bit of lime, grapefruit or lemon, for cooling down during summer heat.
 

          MEDICINAL USES

    Arundina graminifolia belongs to those medicinal plants that are not known in Western Herbalism, and very little known in mainstreem of modern herbalism even in region of its origin. But it has a long tradition of medicinal use in every country where it is native (in Nepal, India, Sri Lanka, Bangladesh, China and all countries of Southeast Asia). And for some local communities, mostly in rural areas, this herb is still a very important traditional cure. 
   Although it is quite polular as an ornamental plant in whole tropical and subtropical Asia, as a medicinal herb its popularity is nowadays only seen among Dai people. In fact Arundina is one of the most important and most commonly used herbs in Traditional Dai Medicine. And as big majority of Dai people live in southern parts of Yunnan Province in China. It was Chinese scientists that conducted most of the modern research on pharmaceutical properties and chemical constituents of this plant.
   In last two decades, due to raising wave of popularity of herbal therapies, also some scientists in other countries of the region, like Thailand, Malaysia and Indonesia, gave some attention to big medicinal potential of this herb. But total number of all research papers about Arundina's properties is still scarce up to date. Yet this combined with the information from many existing ethnobotanical surveys among many different Asian tribes. Is giving us pretty good understanding of how we can properly use this powerful traditional herbal medicine. Which I belive has a big potential to become much more than just a localy known remedy.

 
   All parts of Bamboo Orchid can be used for medicinal purposes. The stems, rhizomes, roots and pseudobulbs has probably very close to identical healing values, and many authors write that simply the whole plant is used as a raw material. But in some sourcess particular parts are specified for specific use.  

   In Traditional Dai Medicine system A. graminifolia is highly reputed as a detoxification herb, and as such it is taken for all diseases before taking the medicine particular for the specific kind of disease. In TDM Arundina is also considered to be a herb that clears heat, remove blood stasis, remove wind and relieve pain. Said to be bitter, neutral in thermic nature and possess attribution of water element.

   In Western Medicine terms Arundina's properties are described as : antioxidant, anti-inflammatory, antidote, antitumor, antibacterial, antiviral, antifungal, diuretic, anti-irritant, demulcent, emollient, antidepressant and immune regulating. Few compounds isolated from this plant showed anti-hemolytic action.

   The whole plant or individual parts of A. graminifolia can be used chopped fresh or dried and crushed. It is usually taken orally in form of decoction (standard dose 15-30g) or infusion. It is traditionally used for treatment of : 

- Poisoning. It is used by Dai people as a folk medicine for the treatment of food and drug intoxication. This herb is also used for venomous snake bites, decoction is drunk while poultice from mashed fresh pseudobulbs is applied on the bite wound. 
   Results of study on A. graminifolia extract, suggest that its detoxification mechanism could be related to its strong inhibition effect on lipid peroxidation, induced by chemical poison. 

- Liver problems. In Traditional Dai Medicine and among other south Asian communities, Arundina is commonly used to detoxify liver and treat liver ailments like hepatitis and jaundice. This herb is one of principal components of the compound formulation called Baogan capsule which was used to treat liver damage and hepatic fibrosis in Dai hospital. 
   Two stilbenoid compounds isolated from A. graminifolia performed significant efficacy of anti-hepatic fibrosis activity against HSC-T6 in vitro.

- Infectious diseases. This herb is widely used to treat both bacterial and viral infections, mainly those of stomach, lungs or skin. Drinking Arundina decoctions is often traditionally prescribed for pulmonary tuberculosis, sore throat, carbuncle, and to prevent or stop wound infections.
   From five flavonoid compounds isolated from whole plant of A. graminifolia, gramflavonoid A has showed moderate, and four other compounds weak anti HIV-1 activity. Results of other study showed that some phenolic compounds form the plant (graminiphenols), also displayed anti HIV-1 activity, and some of it was active against tobacco mosaic virus.
   Two phenantherenes compounds isolated from Bamboo Orchid showed medium activity against Staphylococcus aureus, Bacillus subtilis and Escherichia coli. Study of bactericidal mechanisms observed rupture of cell wall and membrane and leakage of nucleoidal mass. 
  The ethyl acetate, ethanol and methanol extracts of A. graminifolia, showed selective inhibitory activity against the yeasts (Candida albicans, Candida parapsilosis, Issatchenkia orientalis and Cryptococcus neoformans).

- Digestive tract ailments. Beside for being used to fight infections and inflammations of digestive system, A. graminifolia is also used to treat intestinal parasitic infestation. In Bangladesh the roots decoction is used to treat intestinal and biliary colic.

- Urinary track problems. Arundina is traditionally used for treatment of urinary tract ailments, mainly caused by infections and inflammations, like pyretic stranguria and urethritis.

- Pain. Decoction of the whole plant is traditionally used for pain relief, it is said to be helpfull in cases of abdominal pain, rheumatic and arthritic pain, joint pain, body aches.

- Diabetes. This herb is often traditionally taken as a treatment of diabetes.

- Rheumatism and arthritis. Decoctions of the plant are drunk as a remedy for rheumatic disorders, while paste made from rhizomes and stalk is applied topically on affected place.

- Tumors. In India and Indonesia, A. graminifolia is taken as a treatment for tumor. Results of few different studies has showed that some compounds isolated from the plant exhibit high or moderate cytotoxic activity against cancer cells lines such as HSY5Y, NB4, A549, PC3 and MCF7.

Decoctions from this herb are also used internally to treat : edema, beriberi, hernia, sores, hyperliposis, bone fractures and bruises. In Guangxi, China, A. graminifolia is allegedly used to treat mental illness, while Dai people use it to treat epilepsy
   In Sikkim state of India, powder of the rhizome is given to patients with bone fractures for faster healing. Malaysians eats flowers of Anrudina to controll high blood pressure.
 
   In Indonesia, A. graminifolia root decoction is one of main ingredients in Jamu (traditional herbal drinks) formulas used as male tonic for sexual stamina, or to strenghten people to work.

  In TDM system the whole plant decoction is taken for the deficiency of Qi and blood due to postpartum.
 

 Externally fresh parts of Arundina graminifolia are used in such a ways : 

- Scrapings of bulbous stem (might be mixed with coconut oil) are applied to heal cracks on skin and heels.

- Rhizome and stem paste is applied for ear pain and rheumatism.

- Juice extracted from the plant is used to treat ear pain.

- Paste from leaves and stems is applied on boils and carbuncles, once a day for four days.


   Arundina graminifolia whole plant has a high content of flavonoids, polyphenols and stilbenoids, it is also rich in triterpenes, sterols, and contain phenanthrenes and diphenylethylenes, tannins, saponins, fluorenones and bibenzyls. 
   Here are some of constituents identified in the plant: gramflavonoid A, arundinan, arundinaol, medicarpin, butein, sulfuretin, quercetin and its glycosides, kaempfrol and its glycosides, gramniphenols C–G, blestriarene A , shacidin, densiflorol B, ephemerantho-quinone, coelonin, lusianthridin, heptacosane, arundiquinone, arundigramin, plus-catechin; 10 glucosyloxybenzyl-2-benzylmalate derivatives; C-4-alkylated deoxybenzoins; (2E)-, 2-propenoic acid; 3-(4-hydroxy-3-methoxyphenyl)-decosyl ester; p-hydroxybenzyl alcohol; triacontanol; p-hydroxybenzylethyl ether; 3-hydroxy-5-methoxybibenzyl; steppogenin-4'-O-β-D- glucoside.

Abelmoschus manihot - Aibika, Gedi, Bele


      PLANT PROFILE

   Abelmoschus manihot is a perennial shrub from Hibiscus tribe of Malvaceae family. It probably originates from tropical and subtropical areas of southern and eastern parts of China, and from there it was spread to north of India and Southeast Asia. And nowadays it is cultivated and often also grows wild in the South Asia region from India and Sri Lanka, through Myanmar, Thajland, Indonesia, the Philippines to Melanesia, Polynesia and northern Australia. It was also introduced in some regions of Africa and South America.
   It is commonly cultivated as a leafy vegetable, but often also for its medicinal use and sometimes as an ornamental plant, as its big yellow flowers has a lot of charm. It is highly polymorphic species, as its leaves form vary from slightly to deeply cutted palmate or can even have a thin spearhead-like shape. And even on one plant there might be signifficant differences in shape of the leaves. A huge number of differently looking cultivars of Abelmoschus manihot, is mainly due to the fact that this species domesticated plants easily get crosspolinated by wild forms of A. manihot, as well as with other species from genus Abelmoschus. To which among few other belongs Abelmoschus esculentus and Abelmoschus caillei species, which seedpods called Okra are popular vegetable in many regions of the world.
   Abelmoschus manihot popularity is much lesser, as it is little known outside of S-E Asia and Oceania. And even there it stays unknown or little known in many parts of the regions. But in some communities of Indonesia, Papua New Guinea, Vanuatu, Samoa and Fiji, it is one of the most commonly used leafy vegetables. Grown in private vegetable gardens or gathered from wild, but sometimes also cultivated on plantations, and often sold on local markets, in form of bundles of whole stems with leaves. Plantators in Fiji even export fresh A. manihot leaves to Canada and frozen to New Zealand, Australia and USA, where it is much appreciated mostly by migrants from Pacific islands, longing for their traditional food ingredients.

   Although medicinal properties of Abelmoschus manihot are lesser known than its highly nutritional value. In many communities it it is highly esteemed as a medicinal herb, and its leaves are consumed as a remedy for many diseases, from stomach problems, urinary ailments to fever, headache and tumors. In China the flowers of Abelmoschus manihot has been used for centuries to treat even most serious kidneys problems. It was described in two oldest books of classical Chinese medicine, namely Jia You Ben Cao (mid-11th century) and Ben Cao Gang Mu (1578), and officially listed in 2015 edition of the Chinese Pharmacopoeia. 
 
   Abelmoschus manihot was also used in China for centuries as an ingredient in paper making. Nowadays the plant's musilage is still used in Japan in production of special paper called Washi, and in Korea traditional paper called Hanji.


   Here are some of the common names used for this plant : Aibika, Aigiri, Gogae, Kabul (Papua New Guinea), Gedi, Degi, Sarolo (Indonesia), Jungli Bhindi (Hindi), Raan Bhendi (Marathi), Usipak (Assamese), Kantalo Bhende (Gujarati), Phuttu Bhaji (Chhattisgarhi), Sweet Hibiscus, Edible Hibiscus, Manihot Mallow, Sunset Hibiscus, Yellow Hibiscus, Lettuce Tree, Queensland Greens (English), Pele (Samoa, Tonga, Tuvalu, Cook Islands), Bele, Vauvau, Momoke (Fiji), Nuk, Barmai, Kwere (Vanuatu), Slippery Cabbage, Island Cabbage, Pacific Cabbage, Nambelle, Neka, Lema, Gole (Solomon Islands), Te Nambere (Kiribati), Naonit (New Caledonia), Lagikuway, Barakue, Glikway (the Philippines), Paw Fai (Thailand), Bonde, Koto (Sierra Leone), Gbamafetri (Ghana), Tororo-aoi, Kusadamo (Japanese), Dakpul (Korean), Somaradza (Tibetan) ; Chinese names: flowers - Huang Shu Kui Hua, seeds - Huang Shu Kui Zi, leaves - Huang Shu Kui Ye, stem or stem bark - Huang Shu Kui Jing, roots - Huang Shu Kui Gen. And you will find impressive extended list of A. manihot verncular names here

   Abelmoschus manihot in the past was also known under its botanical synonyms like : Hibiscus manihot, Hibiscus palmatus, Bamia manihot, Bamia magnifica and Erebennus manihot, to name just a few.
   And some botanists recognise varieties of this plant like : dissecta, megaspermus, platidactylis, timorensis, pungens, genuinus, or subspecies : caillei, tetraphyllus. But other says that Abelmoschus caillei is probably hybrid of Abelmoschus manihot and Abelmoschus esculentus, or endemic African species.
   And in my and many other scientists opinion Abelmoschus tetraphyllus is a seperate species, and the line between it and A. manihot, should be that all the disputed manihot-like specimens with any kinds of micro-hairs should be classified as tetraphyllus, while only those with glabrous leaves and stems should be recognised as a real A. manihot. That means consider A. manihot as a domisticated form of wild, hairy A. tetraphyllus, that evolved over centuries of selective cultivation of specimens with non-hairy and more juicy leaves, in order to acheive better vegetable type.
   But at the present many if not the most of authors are stating that Abelmoschus manihot leaves and stems are covered with short hispid or prickly hairs.


        CULTIVATION AND HARVESTING

   Abelmoschus manihot is a perrenial shrub, that when young is more of a robust herbaceus plant nature, as only its old stems become fully woody, while young one are quite soft and succulent. It has erect stems, and can reach height of up to 5m, and width of around 3m. In its wild state it can be found mostly in valleys and wet grasslands but also in wastelands and humid rocky hillsides. And it is commonly planted in vegetable gardens in pacific islands villages. It often grows as just an annual plant either due to climate conditions, like extreeme seasonal draughts or cold winters or because of cultivation manner. In temperate climates with mild frosts A. manihot dies back to the ground but can grow back from the underground parts.
   Aibika prefers humid tropical climate, sandy loam and clay loam soil with fair amount of compost, pH between 5 and 7, and sunny position. And in those conditions it can have rapid growth of one meter per month in young plants. The growth of new stems and leaves, its number and size is lesser near and during flowering period, and also decline with plant's age. And for that reason A. manihot is cultivated mainly as an annual plant, as the old plants are removed and replaced with young ones, which are more leaf productive. Its propagation is quick and easy, as its woody and half-woody cuttings are growing roots very fast.
    It can be also grown from the seeds, but the seedlings grow initially much slower than young plants from cuttings. Cuttings cultivation method also accertain you that your young plants will have all the characteristics of the mother plant. As cultivars of Abelmoschus manihot easily crosspolinate with wild forms of A. manihot, as well as with other species of Abelmoschus genus. This hybridisation and common occurance of mutations cause huge variation in morphology of this species. Its leaves shape can be anything from slightly to deeply cutted palmate, and also cordate or spear-like, while its size can be from a fist size to size of a big plate. 
   The leaves color can be from light to dark green or reddish, young stems and leaf petioles are often red or purplish. The leaves look can be even significantly different within the one plant, as it is often changing with weather conditions or growth stage, it is usually smaller in size in older plants and during the flowering period. The flowering of Abelmoschus manihot generally occurs during dry, summer months, but of course vary due to region, for example in China it is during August to October, in Fiji June to November, while in the Philippines it is December to March. The flowers are usually yellow with dark purple centre, but it can also be white with purple center.
   This plant is said to grow best in lowlands at altitudes to 800 m, but I have grew mine in the Philippines at elevation of 1400 m with good results, and it is noted to be cultivated even at heights of 2000 m. There is a huge number of cultivars of Abelmoschus manihot and some might be better adapted to particular conditions than other, for example : narrow-leaved Aibika varieties may be more drought tolerant than round-leaved forms. 
   A. manihot does not require much maintenance and it is usually cultivated in a mixed-cropping system. It is commonly intercropped with low growing vegetables, root crops and banana. It is highly salt tolernt plant, although extensive salinity is slowing its growth. Its growth can be also slowed by deficiency of water or waterlogging in soil. But the plant can withstand seasonal droughts, and is said to tolerate alkalinity and micronutrients deficiencies. 
   With enough watering A. manihot can produce continous abundance of its juicy leaves all year round. The cuttings start to grow shoots after about two weeks and the first harvest is taken usually after 3 months. Since then it can be harvested weekly (stems tops) or even daily (separate leaves) for year or two, before the plants start to be less leaf productive. Seperate leaves, tender shoots or whole longer stems tops with leaves can be harvested. But in case of harvesting only the leaves, sporadic prunning have to be done to curb the height of the bush and encourage better branching, which cause better leaf production.
   Unfortunatelly humans are not the only animals that like tasty, nutritious leaves of Aibika, pests like grasshoppers, caterpillars and aphids, also loves it. The other threats are : Aibika Jassid (Amrasca devastans), Shot-hole Beetle (Nisotra basselae), Green Coconut Bug (Amblypelta cocophaga), Spherical Mealybug (Nipaecoccus viridis), Red Cotton Bug (Dysdercus cingulatus), Red Spider Mite (Tetranychus urticae), Oribius Weevils (Oribius species) and White Fly (Hemiptera species). The plants can be also damaged by Black Shank (Phytophthora nicotianae), Myrothecium roridum and other types of fungal diseases, and viruses like Hibiscus Chlorotic Ringspot Virus (HCRSV). You can find more details about Abelmoschus manihot's pests and diseases and its prevention here.

   Aibika leaves wilt easily, so for longer storage it is better to harvest leaves with the whole stem tops, and seperate the leaves from those stems just before the use. Seperate succulent shoot tips with very young, underdeveloped leaves also storage well. The mature leaves separately are best to be stored in plastic ventilated bags or containers in cool temperatures, it can be also wrapped in bababa leaves and occasionally sprinkled with water for better freshness. The whole stems can be held in buckets or other containers with water, so that the buttoms of the stems would be immersed in water.
