Shaggy, creamy-yellow pompom flowers dance on long wiry stems above finely cut ferny-foliage. This rarely encountered perennial is extremely easy to grow in most soil in full sun. Requires good drainage through winter.

We look forward to posting photos of the gorgeous foliage once our plants grow out a bit more.
