Elephant's ear plant
Alocasia longiloba
A Southeast Asian aroid grown as a houseplant for its long, arrow-shaped leaves, dark green with gray-green main veins, held on tall leaf stalks that Flora of China describes as strikingly mottled chocolate-brown. The RHS calls it elephant's ear plant, a name it shares with the rest of the genus. Flora of China records it in tropical forests and thickets from southern China to Malaysia, at up to 4.9 feet tall. Plants are still sold under former species names that GRIN Taxonomy and Wikipedia now place in Alocasia longiloba, among them Alocasia lowii, A. watsoniana and A. korthalsii, and NC State Extension names it as one parent of African mask (Alocasia × mortfontanensis). Indoors except in USDA zones 10 and warmer. Every part is poisonous: the ASPCA lists Alocasia as toxic to dogs, cats and horses, and NC State Extension says the genus is poisonous if eaten and causes contact dermatitis.
