I am looking for a low-growing, bush-like tree or shrub that holds fruit at the most visible tip of on my corner lot. I would plant a tree, but it needs to be low to avoid obstructing the trees and landscaping behind it. The temptation is to go with something purely ornamental (Texas sage, Lavender, etc) but I really want something that bears fruit if I'm going to be watering it. It needs to be evergreen as well, and tolerant of the heat with occasional brief near frost/frost conditions in winter.
I am in Zone9b, Inland Empire area of California, near Riverside/Redlands. Would a dwarf mango be a good choice? Or is there something else recommended? The corner gets plenty of morning sun and dappled afternoon sun, isn't particularly protected from winter cold. I was considering a manzanita but am interested in subtropical fruit species that might work as well. Thanks!
