The Amaryllis Family: Genus Crinum Hybrids

Crinum [delagoense X acaule]

Crinum delagoense x acaule (c) copyright 2006 Shields Gardens Ltd. All rights reserved.

There are wild populations of natural hybrids between Crinum delagoense (also known as C. stuhlmannii) and C. acaule. One such plant is shown on this page. These are from a farm in KwaZulu-Natal Province of South Africa; the bulbs were removed because the field was to be plowed up and planted with crops. Some are said to be fertile, but we have not had them long enough to test this.

Like C. acaule, this plant is compact: the leaves are less than 12 inches long, and the peduncle (stem) is only 6 to 7 inches tall. The scape is held at an angle. Unlike acaule, which is usually single-flowered, this umbel contained 5 buds.
