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.
