My friend has an avocado tree that died down and came back. She says that when the avocados are ripe, they are almost black. I know that would be a Brogdon, but the avocado she gave me looks more like a Lulu in shape, definitely pear shaped as opposed to the rounder Brogdon. I know that Lulu is used as a rootstock.

Could it be that she has both kinds, or that they cross-bred somewhere from blooms on the suckers and blooms from the top? This is the first year it has had fruit.

Or...is there a tear shaped dark skinned avocado variety that I don't know about? I looked at Pine Island nursery site, and the one she gave me definitely looks like a Lulu, not a Brogdon, but I'll see when it gets ripe what color it turns, I guess.
