Minnieroot is a small, low-growing flowering weed from the tropics of the Americas, now naturalized in Africa and Asia, grown mainly for its tuberous roots and violet funnel-shaped flowers. Its main feature is the popping seed pods that children play with, and it is more often found in fields and roadsides than grown in gardens.

About

Ruellia tuberosa, also known as minnieroot, fever root, snapdragon root and sheep potato (Thai: ต้อยติ่ง), is a species of flowering plant in the family Acanthaceae. Its native range is in Central America but it has become naturalized in Africa (Tanzania in particular), South and Southeast Asia.

Some butterfly species, like the lemon pansy (Junonia lemonias) and the mangrove buckeye (Junonia genoveva), feed on the leaves of Ruellia tuberosa.
