Answer: You have accurately described the growth habit of the Joshua Tree (Yucca brevifolia). It's native to the desert southwest. The tree grows slowly,15-30 feet high, with a heavy trunk and a few heavy branches at the top of the trunk. The trees have short, broad, sword-shaped leaves clustered near the ends of the branches. Old dead leaves hang on the tree. They're not generally pruned - that's just the way they grow!
