Filipendula ulmaria

Germination

Sow indoors Mar-May. Surface sow onto moist, well-drained seed compost. Just cover seed with a sprinkling of soil. Place in a propagator. Ideal temp. 20-25°C. Do not exclude light. Keep moist at all times. Germination takes 3-4 weeks approx. Transplant seedlings when large enough to handle to 8cm pots and grow on in cooler conditions. Acclimatise and plant out after danger of frost has passed.

Growing

Prefers a fertile, humus-rich, moist soil in full or partial sun. Will not tolerate waterlogged soils. Ideal for wet woodlands, damp meadows, ditches or pond margins.

Cultivation

Will self-seed, deadhead if you do not want volunteer seedlings next season. Cut the plant back after flowering ceases. Propagate by seed or by division in spring. In a sunny location the plant will spread via seed. If you wish to sow this fresh seed do so immediately in autumn. In a shadier location the plant will spread via its rhizatomous root.
