It took awhile, but we have finally made a positive ID on this enchanting plant that we encountered on our tour of England and its Gardens. Astrantia, AKA - Great Masterwort is hardy in zones 4 - 9, but if we can find it we will plant it and give it a try. Let us know if you spot plants or seeds of this lovely specimen and we will do the same for you.
Astrantia is a genus of herbaceous plants in the family Apiaceae, endemic to Central, Eastern and Southern Europe and the Caucasus. The Genus name comes from the Greek word for star in reference to the star-like quality of the flower heads. There are 8 or 9 species, which have aromatic roots, palmate leaves, and decorative flowers. They are commonly known as great masterwort, which may be confused with masterwort, Peucedanum ostruthium.- Wikipedia
