Elephant Ear

Alocasia sarawakensis (ah-loh-KAY-see-ah sah-rah-wahk-EN-sis)

Family: Araceae Unknown Herbaceous (3-15 ft)

Alocasia sarawakensis 'Yucatan Princess' is a large leaf, tuberous, perennial cultivar whose species is native to Borneo. It is a member of the arum family (Araceae). It grows best where annual daytime temperatures range from 68 to 77 degrees Fahrenheit, in a shaded site with well-drained, humus-rich, fertile loam, though it does tolerate a wide range of soil types. Divided roots may be started indoors in pots or containers and set outside after the last frost date. Water and fertilize regularly. Before the first fall frost, dig up the pots and bring them inside where they can overwintered. Reduce watering in winter and return to the garden in spring. This plant is typically grown for its foliage and is becoming increasingly popular as a houseplant. It can grow from 4 to 8 feet tall and 3 to 6 feet wide and holds its glossy leaves high on sturdy brick-red stems. The leaves unfurl to puckered, crinkled, glossy, gray-green and have maroon undersides. Although it rarely flowers, its tiny flowers are on a creamy white spadix surrounded by a green spathe. This plant is grown as a houseplant, or if temperatures and moisture levels permit, as a summer ornamental. However, if grown in a pot, the plant will typically not reach its full height. The 'Yucatan Princess' is an elegant large screen or accent plant for your home or garden. Diseases, Pests, and Other Plant Problems: Monitor for spider mites mealybugs, and aphids. Overwatering can cause crown rot, stem rot, and other fungal diseases. The plant is susceptible to high winds and, if sited outdoors, should be in a protected area. More information on Alocasia .
