Limnanthes Douglasii

Bright yellow cup-shaped flowers with white-tipped petals give this one the common name of poached egg plant, which will self-seed freely, future generations continuing to appear and naturalise themselves, germinating and flowering at different times. It is native to California and Oregon, where it thrives in wet, grassy habitats. The Royal Horticultural Society has awarded the prestigious Award of Garden Merit (AGM).
