VP is called upright grower and vigorous. It makes very nice looking elongated fruits that customers will buy. Plant it where you can let it grow as much as you like and into a shade tree.
Cac is not like this. It is moderate with a bushy enough tendency.
There is a VP a mile from me. It sure looks like VP, but the owner could not verify, since the tree came with the property when he bought it. For all I know, maybe it was planted from seed, a VP seed perhaps? I was amazed how good looking the fruits were. He gave me a few, so thanks to him! This would be a very good tree to get scion wood from. (zzlogic___at____gmail) The fruit skin was so shiny and colorful, that I rate it 50/50 that this tree is not a VP clone such as Zill will graft.
