aroid

noun

ar·​oid ˈa-ˌrȯid 

ˈer-ˌȯid

plural aroids

: any of a large family (Araceae) of terrestrial, aquatic, or epiphytic flowering plants chiefly of tropical regions that have tiny flowers clustered on a spadix partly enclosed by a spathe and that include some (such as calla lilies and monsteras) grown as houseplants and others (such as taros and konjacs) grown for food : a plant of the arum family

The aroids are remarkably diverse: although the family includes such familiar plants as philodendrons and anthuriums, it also includes some of the most bizarre members of the plant kingdom: the Titan arum of Sumatra was surely the most sensational discovery of the Victorian age of plant hunting.

—Deni Brown

Philodendrons and other aroids which produce aerial roots along their stems will grow … much better if the growing support is wrapped around with a layer of wet sphagnum moss …

—Bill Davidson

aroid adjective

Each type of aroid plant grows with different needs and characteristics so it is important to do some research before purchasing.
