Flowering rush (Butomus umbellatus) is a tall British native rush that has long narrow dark green leaves which twist slightly as they get taller, and produces pretty umbrella headed flowers with dainty pink flowers around July to August. A valuable native plant providing egg laying sites for adult dragonfly as well as perching and roosting sites. The larvae use the stems to climb out of the water.
It grows well in a sunny position but make sure it has plenty of room to grow if in a basket as it doesn’t like being constricted, so it would benefit from being potted up to a minimum 23cm round basket. It prefers growing with its crown at least 10cm below the surface of the water and is a nutrient hungry plant so will benefit from feeding with slow release fertiliser tablets in early spring
Please note as the plants get taller the leaves are quite soft so will inevitably get bent when packed and transported.
Butomus sharp edged leaves to prevent it being used for fodder; umbellatus with flowers in umbels (parasol shaped clusters)
