Creeping oxalis is a small perennial weed which grows from stolons (creeping stems) 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. Creeping oxalis is native to New Zealand and appears to tolerate a wide range of growing conditions. It is typically found in fairly dry, low fertility, open swards, but does seem to tolerate poor drainage OK and can also thrive under quite high fertility conditions.
