How to plant Filipendula
Commonly known as Meadowsweet, it’s no surprise that Filipendula loves the reliably moist soil found in damp meadows, ponds and stream edges - or any slightly boggy, poorly drained border. The tall, floaty clusters of tiny flowerheads rise well above its maple-shaped leaves, attracting bees and other insects. This tall, hardy perennial is perfect for bringing height to the planting scheme when grown in generous drifts at the back of informal borders, and makes a welcome addition to wildlife areas and meadows.
How to plant
- Plant Filipendula bare roots in spring from February to May, ideally within a week of delivery.
- Soak the roots in water for 3-6 hours prior to planting. Pot into temporary 2 litre (15-20cm diameter) pots, using a good quality multi-purpose compost.
- Plant so that the roots are fully submerged and the buds/crown of the plant level with the soil surface, or with any top growth like leaves or shoots which have developed exposed above the soil surface.
- Grow them on in a sheltered, bright area outside. They can be transplanted to borders in a suitable location after 2-4 months, or once growth is established and the plant easily comes out of the pot with the soil held intact by the roots.
- When planting into border, choose a position in full sun or partial shade. Filipendula prefers reliably moist or boggy soil, and flourishes in the damp soil at the edge of ponds. It’s just as happy in almost any other garden soil or even a container, provided it doesn’t dry out.
- This perennial is fully hardy and does not require winter protection.
- Water-in after planting and keep well hydrated when in growth, particularly during the first year. Filipendula must not be allowed to dry out so summer watering may be necessary.
Aftercare
- Filipendula will start to produce new growth in the spring. Flowers follow from late June to August. The stems will naturally die back in autumn and should then be cut back to 5-10cm above the soil surface.
- These perennials can form a sizable clump after several years which can be lifted and divided to create more plants.
