Also known as oxalis, this is a versatile weed that grows in sun or shade, moist or dry soil. It’s a clover look-alike, with heart shape leaves and yellow flowers. Blooms fade to form upright seed pods that explode when ripe, flinging seeds away from the mother plant. It also roots from stem pieces. It’s happy to grow in lawns, planting beds, gravel drives or vegetable garden paths. Oxalis is a common weed in nursery pots, so be sure to check before adding plants to your landscape. The best way to beat it in the lawn is to mow high and fertilize to grow a healthy, thick lawn. In planting beds, carefully hand-pull or spray with herbicide.
