Bulbine triebneri (Leighton) B.Nord.

Triebner's bulbine

Bulbine triebneri is a perennial herbaceous succulent from Namaqualand and the northern Karoo of South Africa. Originally described by Leighton and reclassified by B. Nordenstam. It is distinguished by its somewhat thickened cylindrical leaves and its striking deep-yellow flower spikes that emerge en masse during spring flowering, creating spectacular displays on the semi-arid plains.
