Soursob

(Oxalis Pes - Caprae) Soursob, a South African native, is a very invasive plant that produces a main tuber-like root, plus several small bulbs. It has three-lobed, heart-shaped leaves with brown or purple spots on top. It occurs widely throughout the cooler regions of Australia. A biennial (each plant survives for two years) it is most apparent during winter and spring, when it produces brilliant yellow, trumpet-shaped flowers in groups ranging from three to a dozen or more. It reproduces mainly from bulbs, which are generally spread through the movement of soil and the dumping of soil and garden waste.
