DESCRIPTION:
Buttercup oxalis (Bermuda buttercup) is sometimes grown as an ornamental. It has compound leaves, each consisting of three heart-shaped leaflets resembling clover leaves. Flowers are attractive, but are a nuisance when they spread into gardens or shrubs like this juniper (pictured here). Flowers occur singly or in clusters on the ends of slender leaf stalks; each flower has 5 yellow petals. This species closely resembles woodsorrel but often grows more upright, has more showy flowers, and reproduces largely by bulbs.

See UC IPM's Creeping Woodsorrel and Bermuda Buttercup Pest Note for more information.
