Deep green, very finely divided leaves form beautiful foliar texture in spring, then broad flat umbels of white flowers rise above in summer. Sun or shade, even very, very dry shade. A very tough plant which will happily naturalise in wild, and not so wild, parts of the garden. I grow it under yew trees and in gravel paths etc. 1m. This would appear to be the correct name for the plant in circulation here as Cenolophium d.
