It has an RU Irish Elegance tag on it, but
I don't think so...
I have had it since last fall, nearly three seasons
it has never bloomed
here is the foliage
here is the bush form, apologies, it got very dry early this summer, got put in the back forty, and though it is clean no spray it isn't showoffable
as you see, very fountain to umbrella shaped, 5 to 7 leaflets foliaged, and as far as I can see thornless
