Lachenalia viridiflora

A South African stunner. Leaves can be either spotted or plain and color of the flowers that seems unreal. This stands out due to the extraordinary blue-green color of its flowers. Its strap-like leaves are typically bright green and smooth. No frost though, a frostless spot outside in the shelter or potted, where they can be viewed closeup when blooming. Only one bulb.
