Purple loosestrife, Lythrum salicaria, 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 purple-red flowers appear from midsummer. Its flowers are extremely attractive to bees and butterflies.
Lythrum salicaria ‘Robin' bears magenta pink flowers over a particularly long period – typically from late spring to late summer. It’s ideal for growing at the pond edge but also at the back of a moist, sunny border – it makes a great choice for an informal cottage or wildlife garden.
Grow Lythrum salicaria ‘Robin' in moist soil. Water frequently in dry weather and cut back old growth in spring. Divide clumps every three to five years.
