Just to point out that the plant being sold by Annies appears to be P. russeliana (herbaceous perennial rather than woody shrub). I purchased from them several years ago. The leaves are large, felted hearts and the plant remains close to the ground. The flowers are pale yellow. I like the plant, but it is not what it was/is represented to be.

For many years I had P. viscosa, which gradually became a significant sized gnarled woody shrub. The leaves are smaller on viscosa (which closely resembles P. fruiticans, although the leaves and the flowers are slightly different in color). P. viscosa passed on this Seattle winter -- possibly just too much rain with unusually low temps. The Annies offer is mis-identified.
