South African bulb that produces tall bare stems carrying clusters of fragrant pink trumpet flowers in late summer — hence the common name “naked ladies”, because the leaves are entirely absent at flowering time.

Growing notes
- Flowers February–April in the Southern Hemisphere and August–September in the Northern — the autumn equinox marker
- Day length triggers flowering — bulbs need a hot dry summer dormancy to bloom reliably
- Leaves appear only after flowering, persist through winter, then die back before the next bloom
- Suits hot dry banks and gravel — resents wet summer ground
