Good things about Wurtz: tree stays quite small, started fruiting when only 4 feet tall, is quite productive, and fruits can be harvested over long period of time as they hold well on the tree. Bad things: i thought the taste and texture were quite poor, at least compared to other avocados we have widely available here. BTW I think Reed is 10x a better avocado.
It's possible my evaluation of taste and texture is not correct because i only had one Wurtz tree, it seemed a bit of a runt, and it eventually died. I've read some other evaluations of it where it was only rated average quality.
