Brooklime (Veronica beccabunga)
As the name suggests, Brooklime is a fleshy, succulent herb which grows in the wet margins of streams and ditches, and also in very damp soil. It is in bloom between May and September, producing spikes of bright blue flowers, but its leaves can persist all year-round. It is an ideal plant for wildlife pond margins as it is easy to control and provides cover for tadpoles and even sticklebacks.
Brooklime has large, rounded leaves and thick, juicy stems that are both creeping and upright. Its blue flowers are borne on the stems in pairs and are very small; they can sometimes be pink.
