This is a clump-forming herbaceous perennial native to marshy areas in mainland Europe and Western Asia.
The erect stems have light green leaves and grow in attractive rounded clumps.
The plant has a lovely, soft and bushy look.
Euphorbia pallustris make a lovely addition to any herbaceous border with the added bonus that during autumn the leaves turn to yellow and orange.
During late spring and early summer small flowers bright greenish-yellow cupped with bright yellow bracts are borne on terminal clusters.
