Lythrum salicaria 'Robert' (Purple Loosestrife 'Robert')

Lythrum salicaria 'Robert' is a tall-growing wildflower that grows naturally on banks of streams and around ponds. It has strong, upright stems, from which long, poker-like heads of bright magenta-coloured flowers appear from midsummer. Its flowers are extremely attractive to bees and butterflies. It is ideal for growing around the edges of a pond, but will also thrive at the back of a moist, sunny border or bog garden. It makes a great choice for an informal cottage or wildlife garden.  Grow Lythrum salicaria 'Robert' in moist soil. Water frequently in dry weather and cut back old growth in spring. Divide clumps every three to five years.
