As far as Toka vs Superior goes, I grow both and think they are both great choices. Toka needs more pruning, aggressive grower in my yard on prunus americana roots, Superior is dwarfy, weeping habit, precocious bearer and larger fruit size. Superior is a more soul satisfying fresh eating experience- you can take a big juicy bite…Toka is also addictively tasty out of hand, and seems like a better culinary plum as well, more meaty flesh and semi freestone. Thank goodness I don’t have to choose!
Here’s a bowl from '15 of Toka with a few Superior, Alderman and VT plums on top, on the bottom row from the left is Superior, Toka, Alderman, Vermont.
