A native of the UK, Lythrum salicaria 'Robert' is a wonderful late season, nectar-rich feast for your pollinating friends. You will enjoy many hours watching the bees and butterflies captivated by the nectar-rich blooms.Known commonly as Purple Loosestrife, because it was believed that the flowers released the holder from stress and strife. Lythrum are a spectacular wildflower and a firm favourite in RHS show gardens. In decline in the wild in many areas, due to habitat destruction, they are deservedly becoming popular in our gardens.Strong narrow square stems are densely packed with 6-petalled star-shaped blooms. Opening sequentially along stems throughout summer and well into the autumn, over neat clumps of attractive willowy foliage - salicaria means willow. Often associated with riverbanks and ponds, Lythrum salicaria 'Robert' is happy in boggy ground or near the edge of a pond, preferring moist soil in a sunny spot. Reaching a height of 90cm and spreading to around 50c, Robert has an RHS hardiness rating of H7, and will die back over winter, ready to sprout again the following spring.
