Harvested my first Rosemary plum from a scion obtained from Bob Purvis. Here is the description from Bob’s website:
Rosemary (J): Tree is upright, productive, later blooming, severely injured at -29F in SW Minnesota. Pollen quality is questionable, but fruit is outstanding: large, reddish black freestone, sweet plums that ripen in early-mid September in Idaho and keep well for 7-9 weeks.
Strikingly similar in appearance to Flavor King. In the picture below, Flavor King is on the left and Rosemary is on the right:
This one may have ripened up a little early due to the split pit. Brix was 19. Very tasty for an Asian plum, but does not have the exotic flavor of Flavor King.
