I actually think I've seen this guy before, but did not pay much attention to it. Your photo has given me an opportunity to add this one to my wish list...maybe I'll find one at the Redlands Festival.
The flower of my clone is about 1.75-2". The canes on my plant are about 20" long.
If you grow this species under cooler temperature, you will have much deeper blue flowers.
I have one of these guys. it is fairly mature. when i bought it it had evidence of having bloomed. Currently it is growing new canes, branching off the older canes...
I dont believe it needs any sort of winter rest, but
I am probably growing it too warm.
