Description
A dramatic dome of stiff, narrow, blue-green leaves tipped with a sharp spine (“our Lord’s candle”). After several years it sends up a spectacular flower stalk up to 10–15 ft packed with hundreds of creamy, bell-shaped flowers — then that rosette dies (it’s monocarpic), leaving seed or offsets. A signature silhouette of SoCal chaparral hillsides.
Wildlife & pollinators
Pollinated almost exclusively by the yucca moth, in one of nature’s classic obligate mutualisms — the moth pollinates the flowers and its larvae eat some of the seeds.
Habitat & range
Dry, rocky chaparral and scrub slopes through the southern ranges, common in the Santa Ana Mountains.
In the garden
A bold architectural accent for hot, sharply drained, low-water spots — give it room and keep the spine-tipped leaves away from paths. Full sun, no summer water.
Propagation
From seed (the usual route) or by replanting offsets from forms that pup. Plant out small; the deep root resents disturbance.

Problems
None to speak of in lean, dry ground; the sharp leaf tips are the main hazard to site carefully.
