The 'Doubled Goatfoot Sorrel' (Oxalis pes-caprae f. pleniflora) is a double-flowered form of the Bermuda Buttercup, native to South Africa but considered an invasive weed in many parts of the world. It is known for its bright yellow, multi-petaled flowers and its ability to spread rapidly via underground bulbils.
