Yucca whipplei, which is now known as Hesperoyucca whipplei, should not be so difficult to procure. It is the most common species of the genus within the next few hundred miles south of here, and was quite common in the hills around San Luis Obispo, where Brent and I studied horticulture at California Polytechnic State University (Cal Poly). I should have taken pups from wild specimens within the region, but I know of no one with wild specimens within their gardens. I can only see them from a distance, and, although within view, they are far enough away to necessitate quite a hike to get to. I never bothered to procure pups from specimens that I encounter directly in the Santa Monica Mountains north of Beverly Hills because they might be a different variety, or related to such a variety. Contrary to dramatic bloom, seed of the species is supposedly rare because the larvae of its very specialized pollinating moth devour almost all of the seed that develops from successful pollination. (The moth pollinates a flower only to provide seed for its larvae to eat.) Seed should be even more rare here because the specialized pollinating moth has no business so far from the natural range of its sustaining species. Somehow, a specimen that bloomed at work produced these few seed capsules. Someone else besides the specialized pollinating moth apparently took interest in its bloom. Although I have no idea what variety of Yucca whipplei the particular specimen is, I am pleased with the seed, and will try to grow them if they are viable when their capsules dry. (I hope that removal from their deteriorating stalk does not compromise their development.) Furthermore, I will get at least one pup from the original parent now that it will generate a litter after its monocarpic bloom. It is likely the variety that I want and am most familiar with anyway, because that particular variety happens to be the most common. Of course, I will procure a pup from a wild specimen within the region of San Luis Obispo if I ever get the opportunity to do so, just in case it is any different from what is growing and now blooming here.
