of the plum world?
Actually, they look great ... especially at this time of year, as we slowly become fruit starved.
What season are they (in the US)?
I think plums are a neglected fruit tree in home orchards; and I mean "Japanese" type plums -- not what 'we' call "Prunes" (or European plums).
They're vigorous, quick to bear fruit, forgiving when pruned, pest free for me, easy to graft multiple varieties to, and excellent early season fruit. The kind of fruit you can only fully appreciate in your own yard -- while bending foreward with juice dripping from your elbows
