Seseli
A relatively new genus to us, related to cow parsley, but from our experience they have very finely dissected foliage, umbels of white flowers, often from pale pink buds. Enjoying a sunny position on well-drained soil.
As with all umbellifers, the heads of numerous small flowers provide a huge resource of nectar and pollen for a wide range of insects from tiny pollen-beetles to large hoverflies.
