Filipendula ulmaria

meadowsweet

Product Image
A familiar sight on the banks of streams or wet ditches, our native meadowsweet is a vigorous, easy-to-grow plant that's ideal for boggy areas of the garden or beside water. Handsome, deeply veined leaflets are held on arching stems, topped with fluffy sprays, up to 25cm across, of creamy-white flowers in summer. The plant forms clumps of upright growth, but will self seed freely in the the right spot.

How to care for Filipendula ulmaria:

Filipendula prefers a moist, fertile soil and will thrive in full sun to partial shade, especially in damp areas like the edge of a pond or a consistently damp border. Mulch regularly to retain moisture and feed in spring with a balanced fertiliser to encourage vigorous growth.

Deadhead spent flowers to prolong bloom, and cut back the stems to ground level after flowering to keep the plant tidy and encourage fresh foliage. Divide clumps every few years in spring or autumn if the plant becomes overcrowded, and keep an eye out for aphids or powdery mildew, which can occasionally affect it.

Sowing instructions:

Surface sow from March to May indoors onto moist, well-drained seed compost. Place in a propagator, ideally at 20-25°C (68-77°F). Do not exclude light and keep the compost moist at all times. Germination takes around 3-4 weeks. When large enough to handle, transplant seedlings to 9cm pots and grow on in cooler conditions.

Acclimatise and plant out after risk of frost has passed. Later sowings can be done indoors between September and October and planted out the following spring.
