Alocasia, a plant that has many fans. Alocasia is a perennial (rhizomatous) and broad-leaved (tuberous) plant from the Araceae family. Currently, it is known that there are more than 80 species originating from tropical and subtropical areas of South America, Asia to Eastern Australia.
Alocasia, (Schott) G.Don
Alocasia as an ornamental plant is very popular, compensating for other popular plants such as orchids, anthurium, aglaonema, cactus and others. Its exotic appearance has boosted its popularity in the world of ornamental plants. One that has received the Royal Horticultural Society Award of Garden Merit is the Alocasia amazonica hybrid.
Alocasia plants have various leaf shapes, basically heart-shaped (sagittate), large leaves growing to a length of 20 to 90 cm on long stalks. Flowers grow on the ends of short, but inconspicuous stalks, often hidden behind petioles.
In the roots there are tubers, for some species can be eaten, but most contain calcium oxalate crystal raphides which can make the tongue swollen and numb, as well as difficulty breathing and sharp sore throats. The underside of the tuber is more toxic. To process the tubers, it is best to boil them long before serving or you can use sour fruit to dissolve the poison.
Alocasia is usually grown in pots, the best way is in the shade such as under a paranet. to protect it from the sun’s rays that are too strong, and reduce the pouring of rain that is too heavy. This plant requires about 40 to 70% light, so it is best placed under a tree, or in the shade of a paranet net.
Alocasia plants, not too resistant to cold air and too hot air. So it must be treated with care and attention. Watering is only needed when the soil conditions begin to dry, preferably with a sprayer. Watering too much or often will cause rot on Alocasia stems. Attacks by ants, spiders and mites can also kill Alocasia.

In the forests of Indonesia, there are also several Alocasia plants, one of which is Alocasia suhirmania, an alocasia plant native to Indonesia. Dra. Yuzammi, M.Sc, an Alocasia cultivator from the Bogor Botanical Gardens, claims to be the discoverer of Alocasia suhirmaniana in Sulawesi, which was named “suhirmaniana” after the former Head of the Indonesian Botanical Gardens, Dr. Ir. Suhirman.
Alocasia in flower markets, has a very diverse price, from per plant to some are sold based on the number of leaves. The price range starts from Rp. 25 thousand to over Rp 1 million. Allocation reproduction from small tubers grows into alocasia tillers. After growing, then in a few days will separate from its mother. Propagation by cuttings is cutting the stems just below the oldest leaves, then immersing the cut stems in water. A few days later roots will appear.
In caring for Alocasia plants, it is important that the soil must be porous and should not be too dense.
Leaves, must be wiped clean with detergent frequently, to remove adhering dirt that can sometimes cause disease for Alocasia.
Dormant (short sleep)
Like other plants, alocola goes through a period of dormancy, where the plant suddenly dries up, then disappears from the soil surface. To overcome this, it is recommended that the media should be replaced every 6 months. Good media plays an important role in every plant. Dormant can be caused by soil conditions that are too hard, so the roots are difficult to penetrate, and the plant will become dormant (like dead). Media conditions must also be wet not dry.
- During the dormant or “sleeping” period, the allocation of tubers continues to grow even though the leaves do not want to come out.
- Dormancy can last up to a year. But once “wake up” the plant will release a lot of leaves.
- When there is dormancy, just let the plant stand, do not scrape it because it will cause rot.
- Reduce watering, moisten in a damp place. Water once a week so the tubers don’t rot.
- If the care is good, the plant will not experience dormancy. Usually because most of the watering while the heat is less.
The media used are ferns, bamboo leaf compost, cow dung in a ratio of 1: 1: 1. You don’t have to plant it in a pot, it can grow well in the yard because it actually grows in the forest. Sometimes spiders or other small insects attack, so the leaves turn yellow, you should throw them away or you can spray them with insect repellent.
