I bought this plant last fall. I saw it growing at a local tree farm and it was beautiful. They said they always cut it back to the ground in spring and it grows to four feet tall and wide by end of summer. So far this spring, I have seen only very tiny shoots at the base of the otherwise dead-looking bare plant. Maybe it is slow to emerge. It is planted in full sun. I will report more as the season continues.

Love it!! I planted it in full sun in late winter while it was dormant and only about a foot high and this summer it shot up to about 5' and bloomed and bloomed. Stunning flowers, fast growing and very tough in full sun, high heat (we had two weeks of 104F dry heat this year) and little water. I dead headed once in summer and it gave me another flush of beautiful purple flowers. Highly recommended!
Shoal Creek is a hybrid, and may not come true from seed. Tends to be more showy than open pollinated cultivars, with longer bloom spikes up to 12" long. Color is also a little more vibrant. Blooms (lavender-blue) in both spring and fall and is fairly drought tolerant.
