What cultivar is it? The three in my pic are left to right Ukigumo, Purple Ghost and Orange Dream. They're a bit of a passion of mine actually,I've got 14 was 15 but one died over the winter.
sorry, I don´t have the slightest idea, didn´t keep the tag, but I am planning on getting another one ( the second one that I have was damaged from weight of snow, but it´s still alive)
It'll probably come back, the reason I ended up with so many was my garden was invaded by a herd of cows who ate them so I brought replacements then the originals started to grow back.
