Oxalis purpurea

Oxalis purpurea, the grand duchess, is a bulbous plant native to South Africa, highly variable in the wild, with flowers ranging from white to pink and purple, often with a contrasting yellow throat. Rounded leaves, sometimes marked with dark blotches, form a low rosette from which broad, cup-shaped flowers emerge, opening in sunshine. Flowering occurs in autumn and winter. It grows in sandy, well-drained soil, in full sun, with a dry summer rest during the bulb's dormant period.
