It's going to take a few years to get that tall. I think you have planted yours in the ground so it should eventually get there. My neighbor has several that large but I don't know how long they've been there. I don't have CG so not sure exactly how large they get, but I'm sure someone who does will let you know.

I just posted a photo of one I planted out recently that's about 3' tall. It was a cutting about two years ago kept in a pot and wintered over. It's the third picture in the post.

Here is a link that might be useful: Brug link

Brugs are very variable.My first brug was a 5" plant. In 5 months time it grew to 4 feet without any fertilizer or knowledge how to grow it. I think it does help to plant it in the ground for faster, bigger growth. Your conditions, grow habits, fertilizing, watering, soil all can effect the growth rate. Just keep fertilizing and watering and while it might not get 6-10ft. this year you should at least see some blooms. Good luck!

I agree with Theresa, a few yrs back I found one small yellow brug at home depot, .79 cents took it home planted it in the ground and in no time it reached 6' same year got lots of blooms, winter time it dies to the ground, but comes back on its own, this year is kind of slow to recuperate but none the less is alive.
