Lythrum salicaria
(Purple Loosestrife, Two 1-Litre Plants)

Marginal, upright hardy perennial with purple-pink flower heads from mid-summer

Price is for Two Established Plants in 1-Litre Containers

Description

Lythrum salicaria is an architecturally striking hardy native perennial that brings dynamic height, vibrant colour, and vital ecological value to the garden. An ever-present of the wilder margins of untouched areas here in the south-west, this wetland classic, commonly known as Purple Loosestrife, is famous for its statuesque, poker-like flower spires that rise proudly above borders and watersides from midsummer through to early autumn. It forms robust, dense clumps of upright stems clad in handsome, willow-like lance-shaped green leaves. In mid-summer, it is topped with dense, tightly packed spikes of small, star-shaped vivid magenta-purple flowers that provide a stunning vertical feature and fade out neatly to provide vertical interest and wildlife sanctuaries well into autumn.

Growing Advice

Position Lythrum salicaria in a bright, full sun position to get the most vibrant flowering display and sturdiest, most upright habit – though it can often also do well in partial shade. It actively prefers fertile, deep, and reliably moist soil. It performs exceptionally well in places where the ground stays naturally damp, making it ideal for heavy clay borders, bog gardens, or shallow pond margins with up to 5cm of water over the crown. It is an exceptionally low-maintenance and fully hardy (H7) choice. Simply deadhead the spent flower spikes to prevent self-seeding, and cut the stems back to the ground in late autumn or early spring to clear the way for vigorous new growth.

Before ordering with us please make sure you read the pages below to help you understand what to expect when buying plants online from a nursery such as ours. For instance the photographs in our listings are intended to give you an impression of our plants in their mature (and usually flowering) form. The last photograph in this listing provides an indication of the size of the plant to expect when you buy from us. It is not a guarantee of the way the top growth will look when you receive the plant(s), as this will depend on the time of the season you have ordered the plant and it simply isn’t possible to provide photographs of the plants at every stage of growth during the year. Plants ordered in spring, autumn or winter for example may have much reduced or tired top growth that will regrow later in the season / the following season and you should be aware of this when ordering at these times. If you have any questions about the current condition of any of our plants please do get in touch, or see the links below for more information about what to expect.
