This was named for Princess Sturdza’s garden at Le Vasterival in France and that should be recommendation enough. Neither pink nor lavender but firmly positioned in that descriptive Bermuda Triangle of the in-between which allows it to mingle effortlessly with a broad palette of colors. A vigorous grower to 5′ with deep royal plum coloured stems and flowers for weeks in September.
