Key Distinguishing Feature

Similar in appearance to Clover, Creeping oxalis appears with 3 heart-shaped green leaves. This plant has thin wiry stems that flourish Small Yellow flowers.

Creeping oxalis is a small weed which grows from stolons and is typically found in lawns. It doesn’t have underground bulbils, though the stolon system is still an efficient form of vegetative reproduction for this species.

It allows creeping oxalis to spread out through turf to form quite dense mats at times. It is helped by its tolerance of many of the commonly used selective turf herbicides.

It has little yellow flowers which help make the plant obvious at those times of the year when it is flowering.
