Cnidium silaifolium (Cenolophium denudatum)

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 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 in appallingly dry conditions and in gravel paths in full sun etc. 1m. This plant is known in horticulture in the UK as Cenolophium (a completely different plant) and steps should be taken to correct this cock-up.
