|Scientific Name:||Hesperoyucca whipplei|
|Size:||up to 13 feet|
|Habitat:||chaparral or coastal sage scrub
|Blooms:||April to June|
One of the things I associate with June in Southern California is the presence of flowering Yucca stalks dotting the slopes of the neaby mountains and hillsides. Yucca blooms from April to July, usually below 2000' but sometimes up to 8000' in elevation. Flowers are usually creamy-white, but east of the Santa Monicas it is said they can be a dramatic dark purple or pale pink. A particular Yucca plant only blooms once, then dies. In addition to seed dispersal, the plant may also produce offshoots around the old roots. Hesperoyucca whipplei is one of two Agave plants in the Santa Monicas.
Rivaling the showy late-spring flowers is the foliage of this plant, consisting of needle-sharp speers up to three feet long that emanate from a base that sits flat on the ground. Native Americans had a variety of uses for the foliage, weaving ropes, nets and baskets. They also coaxed soap from the roots and fashioned foodstuffs from other plant parts.
Often noted when talking about this plant is the symbiotic relationship it has with the Yucca moth, its only pollinator. The Yucca moth (Tegeticula maculata) gathers a large bunch of pollen from one plant and flies with it to another. She burrows a hole in this second plant's seedpod, deposits her eggs, and covers them with the transported pollen. The emerging caterpillars lower themselves to the ground and bury themselves for a year before emerging as moths.
