This just may be my all time favorite desert plant, of course I say this about every plant... But I do love it!
The first winter this plant lived through an Idaho winter it was a dream come true. Many winters later it is now a large trunking yucca. It was grown from seed that was mail order from California, and is the only place I have seen Y. brevifolia with such long leaves. The leaves on this Joshua tree are up to 18 inches long unlike most brevifolia that are 6-12 inches!
About 2 winter ago the top rotted off and now has regrown 11 new crowns. I doubt all will grow and branch but it will soon be a yucca tree. And too answer the question about the winter the top froze off, no it was not a very cold winter. What killed the top was a warm fall with heavy snow and a couple of nights near 0 deg F., this is much harder on them than a winter with -10 deg F or colder.
50deg F one week and 4deg F the next, very hard on plants.
If you live in a warmer zone 5 or better give it a try, they grow fast from seed and should start a small trunk after about five years, and can grow over a foot a year! as adults.
As always keep plants high and dry the do much better in cold climates!
This is a sucker clone from the above j-tree.
This is one I moved to higher grown and has done much better!
Another one I moved to higher grown, should start showing much improved growth.
These next 2 are doing much better, again moved to higher ground.
One year on higher grown and has grown over a half a foot or better!
Parting shot, a scorpion my wife caught in the house. Smaller than the last one.
"Harmless" But still hurts!
Back outside safe under a rock, and this weekend a new door sweep is growing to keep these guys out. lol
