Yeah, it is, but it gets a lot of sun, and I water it every other day with drip irrigation spaced all under the drip line.. Fertilizer goes into the drip system at just the right rate each week. We've got great drainage, and just the right weather for it.
It also took a few years of pruning it to build up the thickness of the inner canes, for it to get taller without canes flopping down, limiting it's height.
I think if I just let it grow naturally (or pruned heavily), it would probably be limited to 4' or 5'.
Anyway, it's pretty much reached the limits that it can stretch out to, so the newest growth just keeps the middle well filled in.
