Saw these yuccas in the Santa Rosa mtns. of Az. Started with three small seedlings 25 years ago. Two of which are now about 6 ft. tall and decided To bloom the first time. (Sept. 27, 2017). They both have some high shade under an oak tree, and a cypress. I suppose they would have grown much faster and bloomed sooner if if I'd watered them more. Impressive plants with the wide head of stiff leaves. One is a beautiful glaucous gray, the other more of an olive/ gray. I hope to play the yucca moth and cross pollinate to get seeds. ( the yucca moth does not naturally exist in the Santa Rosa area of No. Calif.). One thing I've read is that after the Dead bloom stalk is cut one must be careful of rot starting at that point and traveling down the trunk, killing the yucca. This would... read more

This Yucca is a naturally occuring hybrid between Yucca baccata & Yucca elata (baccata elata).

I've seen these growing in the wild on the West Ruby Road Trail in Arizona (South of Tucson), off of Interstate 19 through to Ruby, AZ and on to Arivaca, AZ.

This cold hardy tree Yucca is a native of the US southwest where it grows in mountains and valleys. It branches just barely above ground but usually not after that. Has long, stiff 1" wide leaves that are not too compactly spaces along the stem compared to most other tree yuccas. Tolerates more shade than most species.
