Q.Is My Plant A Joshua Tree?
This plant was grown from a package of seeds and identified as Joshua tree seeds. It’s now 5 years old and about 30” tall. Can you take a look and see if it looks like it truly is a Joshua tree? I keep it indoors most of the time. I’m in the correct USDA hardiness zone but I assume the amount of rain here in Georgia would not be good for the plant if left outdoors all year. Thanks for any thoughts or comments.

It does appear to be a young Joshua Tree.
