Intriguing to me is the dark blue almost black stems which emerge in spring. The insignificant yellow flowers are borne on a three feet tall bush with soft gray-green foliage. One plant has spread into a clump five feet in diameter, truly a handsome bush throughout spring, summer and fall. | Ratings| overall | 10 | | how easy | 10 | | flower | 10 | | foliage | 10 | | propagate | 10 | | fragrance | n/a |
