Alocasia sinuata is native to Philippines and very well known. It grows in the limestone forests of Samar, Leyte, and parts of Mindanao in the Philippines.
It is a medium-sized, rhizomatous perennial reaching up to 35 cm in height with a thick stem. The leaves are 22-27 cm long, thickly coriaceous, and dark green. These plants begin to be green and develop into darker green, with almost metallic gray patina and dark green sunken veins. Alocasia quilted dreams blooms in spring and summer at the end of a short stalk, but are not conspicuous; often hidden behind the leaf petioles. The flowers are light yellow in colour and are not really showy.
Alocasia sinuata can be grown in partial shade. They don’t need direct sunlight but benefit from a little. Direct sun will cause the leaves to burn, so avoid placing the plant in a spot where it will be exposed to direct sun for a prolonged period. It is not tolerant of low-light situations. Rotate your plant periodically to ensure even growth on all sides.
Alocasia quilted dreams needs the humidity level of 50% or higher; however, they will tolerate low levels with no harm. Mist the leaves regularly, place a humidifier nearby, or use a pebble tray to raise the humidity. If you do mist the plant, keep an eye out for fungal plant diseases caused by wet leaves.
The plant grow best in warm temperatures. Maintain temperatures 60 F to 86 F. They will falter when temperatures drop below 50 F for prolonged periods of time. Avoid cold drafts and sudden temperature changes.
Alocasia sinuata need rich, moist soil and nearly all are perfect at the edge of a pond. The plant can be grown in a few inches of standing water, and can be added to water gardens as emergent plants (the roots in water and with the soil just covered with water, but the plants not submerged).
When grown in pot, the plant need porous soil that has excellent drainage. An ideal soil mix would be equal parts of houseplant soil, peat moss, and perlite. These potting mix ingredients hold just enough moisture and provide excellent drainage. Repot once plant has completely filled the pot. The pot size often appears quite small in relation to the size of the plant this is because the plant grows best when root-bound in a small pot. Avoid rushing to move the plant to a larger container.
A little dryness to the surface of the soil is helpful. Allow the top of the soil to dry between watering to ensure the plant isn't sitting in soil that is too wet. During the winter, the plant will go through a dormancy period and will require less frequent waterings as the soil will take longer to dry. Do not keep them evenly moist. When watering, thoroughly saturate soil until a little water runs out of the bottom of the pot.
Fertilize sparingly as they can be hurt by too much fertilizer. 1/4 strength every two months is adequate. Use a balanced fertilizer like a 15-15-15 or 7-9-5. No fertilizer is needed in the fall and winter months. Before applying, make sure the soil is damp to avoid burning the roots.
The plants continually produce new leaves throughout the growing season. The older leaves that gradually die off can be removed to keep the plants looking tidy. Damaged leaves are usually a sign of a fungal disease and the plant should be treated immediately.
Alocasia quilted dreams can be grown as annuals, starting with new plants each year, or may be kept over the winter (hardy only to zone 8). Plants that have formed bulbs can be dug, dried and stored, after frost has killed the foliage. Those without bulbs are harder to keep indoors, although it may be possible to keep them going as houseplants if kept in a warm, bright location.
Although they can be grown from seed, to grow large plant, start with a large bulb or rooted plant. The plants have tuberous rhizome roots that you can cut into sections to grow new plants. It will take a few weeks for the first leaves to appear from the bulb. These frost-tender perennial plants are best started indoors, potting up the bulb in March, placing the top of the bulb close to the soil surface, and keeping it in a warm location until it is planted outside when the weather warms up, usually in late May or early June. Provide copious water and fertilizer as the plants grow, especially for those in containers, as they are heavy feeders.
Pests and diseases:
Alocasia sinuata are not susceptible to insects but can suffer from root rots and bacteria diseases if over watered under cool temperatures and high humidity. Root rot can affect the plant if you overwater the potting soil. Make sure that the soil is evenly moist but never waterlogged, soggy, or too damp. The tuberous roots can quickly start to decay if they grow in overly-damp soil.
