Water chickweed ( myosoton aquaticum or stellaria aquatic)
Record submitted 28/09/2015 by Fiona Bruce
This pretty little flower is blooming in profusion down near the lock (at the side of the path between the lock and the stile onto the riverbank). I think it is most likely to be water chickweed although I’m happy to be corrected. It has five petals, deeply divided, 10 sepals, cordate (heart-shaped) leaves opposite each other and grows in a straggly way with many branches. Its stem is hairy and slightly sticky. It is a perennial and flowers from June to October.
