We planted ours as a small (10" diameter) plant in 2004 in our front yard. It is now about 3 1/2 ' in diameter with 3 separate "bunches"; still hasn't gotten a trunk at all. However, much to my surprise, I noticed a bloom stalk is starting to come in from one of the bunches! I thought it would be YEARS until it bloomed for me, as I assumed they didn't bloom until they were well off the ground and were mature enough to have the 'tree' form. What a great surprise!

Probably one of the, if not the, most attractive yuccas.
I never get tired of looking at mine, foliage strongly silver blue, with a bold attractive silohette. I grow mine on a slightly raised area to help with drainage in extended rainy periods, as it is sensitive to too much moisture.

Very striking blue-white leaved yucca with minimal branching. Looks a bit like Yucca rostrata, but no variegation of the leaves, and the leaves a stiffer and more dangerous. From N Mexico
