OOps-It's a Purple Pony Dwarf Flowering Plum Tree, if that helps.

Tends to produce crossing, layering branches resulting in a dense display of purple leaves. Flowers comparatively subtle, fruit not seen here. Wonder about hardiness, other issues in your area. The one I bought was grown in California, perhaps the one grower accounts for all current wholesale production. Was not growing this one at the time but many long-established purple-leaved plums in my area were damaged by the 1990 winter, when temperatures got into single digits F.

Before I planted one myself I was aware of characteristics of the cultivar due to it having been grown, assessed (and discarded) by the world authority on purple-leaved plums, who resides in Seattle. One of the things he observed is that the tree is not particularly dwarf. In your region the Minnesota origin selection 'Newport' would probably be a much better bet.

It's not a bush either. If you must have dwarf then maybe Prunus x cistena would suit.

thanks bboy-
I looked for pictures of the Prunus x cistena. Unfortunately I'm looking for more of a tree. Any other suggestions?

There's a larger-growing version called 'Big Cis'.

That 'Big Cis' is one beautiful tree. I searched all day long and didn't come across anything as near perfect! I keep searching the web to see how to care for it, to see if it is disease resistant and what it looks like mature. It's really a nice height and shape. Maybe it's not very common?

If you're worried about that kind of thing a stone fruit (Prunus) may not be a good choice for you.
