I have one in a pot for a couple years now.
I have another one to chop and dig up this spring. They grow like weeds in my yard because my neighbor has 4 large ones along his driveway.
Beautiful trees, great flowers and autumn colors.
Looks like a good starter for a broom style.
My experience with most Prunus is that they are magnets for every conceivable pest, bug, fungus, etc. But I keep trying them. When they flower I start thinking again that they might be worth it. Anticipate more aggressive pest management.
