I almost had a triloba growing here - the seedlings were about 60cm tall - and then the wife found out about the smell of the flowers and their propensity to become a weed over here - so I had to pull them out.
That's why I know those on the other side of the pacific like paw paws to be called papayas
BTW - am I missing much as far as the taste of your paw paw is concerned??
