Oxalis pes-caprae

Bermuda buttercup is a bulbous, winter-growing Oxalis from the Cape winter-rainfall region with bright yellow flowers, and a notorious weed wherever it has been introduced. It grows from autumn to spring and goes dormant as underground bulbils in summer; contain it in pots and never let it into the garden in mild climates.
