Description How to Grow More Info Delivery

This Purple Loosestrife, Lythrum salicaria ‘Robin' can be very long-flowering, with upright magenta pink flower spikes from late spring to late summer, making it perfect for cottage garden borders. Although they are showy and robust, Lythrum are easy to grow, hardy perennials when grown in a moist border in full sun, where they are hard to beat for summer colour. Height: 90cm (36"). Spread: 45cm (18").

Flowering Months
Feed and water Loosestrife plants regularly until fully established. Remove faded flower heads before they set seed if seedlings are not required. Cut back old foliage in late autumn. Overcrowded clumps of Lythrum can be lifted and divided in spring.
Lythrum is a versatile plant that will happily grow in any fertile, moist soil in full sun.
