Purple loosestrife

Vigorous variety and long flowering

A star in a border where it will flower from summer until autumn. The vivid pink flowers appear in bold spikes and will make a colourful statement.

Where?

A great choice for a damp shady spot where the plant will spread slowly each year.

How?

Best in moist or wet soil. Enrich the soil with organic matter before planting - home made garden compost or well rotted manure is fine. Water frequently in dry weather until your plant has established. Cut back old growth in spring when new leaves are spotted at the base of the plant.

This plant is a relative of Purple Loosestrife - a native of wet ditches in Europe and Britain.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
