It's very pretty.
I've heard they don't like to become root bound before being transplanted. I know this, yet mine always seem to sit in cell packs, waiting to be planted. Duh!
This year I got a really tall variety, from Johnny's

I DID get them planted in the garden early, near a fence so if I need to tie them, AND, I even remembered to pinch them to promote branching. But I still have some others in cell packs in the greenhouse waiting. Hopefully this week yet.
Here's one that overwintered for me. I think I got the seeds from the Piggy Seed Swap but of course, the tag is missing so I'm not sure. But I like it a lot. It looks a lot like yours!
