Oxalis

nounStandard termFarming

A large genus of flowering plants known for their clover-like leaves and sour taste.

Any plant in the genus Oxalis, commonly known as wood sorrels or false shamrocks. They feature distinctive divided leaves that fold up at night and produce small, five-petaled flowers. While many are grown as ornamental houseplants or garden perennials, several aggressive species are considered stubborn agricultural weeds due to their persistent bulbils and creeping root systems.
