Noteworthy Characteristics

Ornithogalum regale, commonly called royal berg lily, is a bulbous perennial native to the northern Drakensberg mountains in KwaZulu-Natal Province, South Africa. In the wild these plants are found on nearly sheer cliff-sides in shallow, rocky soil, growing and blooming during the rainy summer and then going dormant during the winter. The plants reach 2-4' tall, with strap-like, glossy leaves emerging from the bulbs. The pendulous, bell-shaped flowers are 1-1.5" long, cream to light green in color, and held on strong flower stalks.

Genus name comes from the Greek words ornis meaning a bird and gala meaning milk for the white flowers.

The specific epithet regale means royal.


No major disease or pest problems reported. Bulbs may rot in heavy, poorly draining soil.
