I have several California Pepper trees; and I am quite fond of them as long as they are pruned.
Very tough tree, hard to kill.
Not good in high wind areas since they have shallow root systems. I never water directly over the tree, rather I water on the perimeter to force the roots to grow out and provide more stability.
Like humans, only the females are really messy as they drop berries that smell like pepper (which I like) – or is that males?
