Here you can see that some earlier clumps are already forming big seedpods when my taller clump beyond is still in bloom: I am surprised to get so much seed set. I had read that each species of yucca has its very own Pronubia moth that cannot pollinate other species...perhaps our local Yucca glauca is similar enough to Y. elata that they are able to set viable seed?
Almost anyone who gardens in this area and grows these plants is sure to have some interesting observations: some specimens have an amazing amount of frilliness on the leaf that is decorative in the extreme. The only sad thing about this plant is that it hates being moved. You had best start with a young plant or seedling, and make sure you put it where it is to stay. Some forms are rhizomatous--so watch out! removing a large clump could be a challenge!
I should really be blogging about firescaping and the issue of fires in Colorado, since that is high on everyone's agenda right now: there are a dozen or more massive fires around the state. That blog shall come...but meanwhile, let's just enjoy this tough and rewarding native succulent that should be more often seen and grown!
