These are related to Ornithogalum, and have similar spikes of flowers, often white with a green stripe along the centre of each petal, but there are also species with yellow flowers. Like so many bulbs, they come from South Africa, but they are reasonably hardy and seem to be easy to grow.
Albuca spiralis has flowers that are green with pale yellow margins.
