One or two leaves are produced annually by a Lachenalia peersii bulb. The strap-shaped leaf grows longer than 20 cm and about 2 cm in width. It often has a maroon tinge, mostly on its lower surface only.
L. rosea, a more widespread species, never has more than one leaf. It also has longer stamens that tend to protrude outside the corolla mouth. In the flowering cluster seen here it is hard to determine whether any of the plants has two leaves.
Leaf margins curve in smoothly, the longer leaves lying on the ground (Bean and Johns, 2005; Duncan, 2010; iSpot).
