Lagarosiphon major – Curly Waterweed
Other common name: Curly water thyme
Genus: Lagarosiphon are semi-evergreen, submerged aquatic perennials forming a cluster of branched stems clothed in spirally arranged, linear-lanceolate leaves, and tiny white or pink flowers in summer.
Details: All plants in GB are female; all dispersal must therefore be by vegetative means and is likely to be by fragments. Curly waterweed is widely naturalised and invasive throughout southern GB, becoming scattered further north.
