double flowering plums, just year old rooted plants and they're flowering in the bin while they wait to get planted out. I have thirty, so maybe put a dozen into pots for our fall sale and the rest into the ground for bare root next spring. this species of plum doesn't really make an edible drupe, it's a showy bush. I have a twenty five year old one that sprawls, never pruned and it's six ft tall and ten ft wide.
