Samolus valerandi is a species of water pimpernel native to a very wide area across Europe, Africa, Asia, Australia, and the Americas. Common names include Brookweed, Thin-Leaf Brookweed, Water Cabbage, and Water Rose.[3]

Ecological aspects[edit]

Shallow water and wet soils. Along creeks, ditches and seepage areas.


The plant can be grown in ponds, bog gardens, and damp areas in the garden. S. valerandi prefers light (sandy), medium (loamy), and heavy (clay) soils, preferably neutral or basic (alkaline) soils. It cannot tolerate shade and likes a bright, sunny position. It requires moist or wet soil and can even grow in water. The plant can tolerate maritime exposure and is self-fertile. S. valerandi is sometimes grown in aquariums, although they seem to last only a limited time when grown fully submersed.
