The height is listed here at 4'; mine has been in the ground about a year and she is a sprawling monster, at least 4.5' tall and nearly twice as wide. I haven't pruned her hard or "held her up", because I wanted to see what she'd do on her own. Thus far she seems to want to be a huge, octopus-style bush. Tends to bloom on the ends of her canes, another reason I'm allowing her to sprawl hoping that it will produce some self-pegging results. Very vigorous and reasonably healthy in my PNW zone 8 garden.
