I have several. They got too big for the small bed they were in, so I just moved them into the lawn as stand alone shrubs. Great companion for those early spring bulbs.

I have Prunus glandulosa (lol, put it that way and it sounds as if I have some sort of disease!). I bought it a few years ago and, trying to push my luck, planted it in a somewhat shaded position. It needed full sun, so I moved it to a better spot. I like the look of it, but I do wish it bloomed longer. Yours is very pretty thyme2dig, I like the daffs with it too. :-)

I don't know how 'dwarf' this shrub is though, I think it will get from 4-6 feet tall and wide in time.

I had two of them in my old garden. I loved them when they bloomed but the blooms were fleeting and usually were washed away even more quickly by spring rains. In zone 5 it bloomed the same time as the Red Bud trees.
