Botanical name: Oxalis corniculata
Creeping oxalis is a perennial weed with a prostrate growth habit. It can be identified by its light green heart shaped leaves, very similar in appearance to clover. The flowers are small, about 3-4mm in diameter and bright yellow in colour containing five petals. When seed pods mature they dry out and explode, causing the seed to spread. Plants contain a tap-root which can make it very difficult to control.
