I did some research of my own about this and I'm now under the impression that all pomegranate "shrubs" can self pollinate. I have a pomegranate shrub of my own and would like to plant another about 10ft. away from it. I saw a few pomegranate trees (not decorative) for sale at a local Walmart and they consisted of a tree formation with a single trunk about a couple feet in length. Can different species of pomegranate trees and shrubs cross pollinate with each other. If so, would this create cross species of pomegranate fruit?
Sorry about sideways pic. Don't know how to make it right side up:)
