Sorry the offsets were small. It seems to grow slowly for me but I like the color as well. Because I grow in pots, it can be hard to properly place the large ones.
You might want to make sure that Pacific Blazing Star gets lots of room. The rosettes get over 8" and it reproduces rapidly as well. I've been working on what to do with it. Moved some to a trough but the main box is falling apart. This is a recent pic, its faded a bit at the moment and this is after thinning this spring. That was a 10" x 12" box that you can't see.
