Botanical name: Oxalis corniculata
A perennial creeping, rhizomatous dicot, often mat forming with a prostrate growth habit. Oxalis possesses light green, heart shaped trifoliate leaves which can often be mistaken for clover, although the leaves are much smaller at around 4mm long and are typically a lighter, lime green in colour. Possesses small woody taproots that can make control of the weed difficult due to that plants ability to regenerate from subterranean vegetative parts. The flowers appear in spring and summer and are small, about 3-4mm across and are bright yellow in colourÂ with five petals.Â When seeds mature pods explode spreading seeds 3 meters or more and causing the weed to proliferate rapidly.
