PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The ideal time to plant Thalictrum ‘Ankum’ is during spring, when the soil has begun to warm. This gives the plant a full growing season to establish strong roots.
Autumn: Alternatively, early autumn planting is also suitable. This allows the plant to settle in and prepare for vigorous growth the following spring.
Site Selection
Sunlight: Thalictrum ‘Ankum’ performs best in partial shade, where it receives dappled sunlight. It can also adapt to full sun, provided the soil remains consistently moist.
Soil: Thalictrum ‘Ankum’ thrives in moist but well-drained soil. Enrich the soil with organic matter, such as compost, to improve its fertility and moisture retention. Avoid waterlogged areas, as poor drainage can lead to root rot.
Planting Instructions
Prepare the Site: Clear the area of weeds and loosen the soil to improve aeration.
Dig the Hole: Create a planting hole twice the width of the root ball and slightly deeper than the pot.
Soil Enhancement: Mix compost or well-rotted manure into the excavated soil to boost nutrients and drainage.
Positioning: Place Thalictrum ‘Ankum’ into the hole, ensuring the top of the root ball is level with the soil surface.
Backfill and Water: Fill the hole gently, firming the soil around the roots to eliminate air pockets. Water thoroughly to help the plant settle.
Watering Requirements
Growing Season: Keep the soil consistently moist but not soggy during the active growing period. Regular watering is essential during dry spells.
Dormant Season: Reduce watering in winter, as Thalictrum ‘Ankum’ requires minimal moisture during dormancy.
Feeding
Spring: Apply a balanced, slow-release fertiliser in early spring to encourage healthy new growth.
Mid-Summer: A light top-dressing of organic compost or a diluted liquid fertiliser can support flowering and maintain vigour.
Pruning and Deadheading
Deadheading: Remove faded flowers throughout the blooming season to encourage additional flower production and keep Thalictrum ‘Ankum’ looking tidy.
Autumn Pruning: After flowering has finished in late summer or autumn, cut back the plant to ground level to prepare it for winter dormancy.
Mulching
Spring Mulch: Add a 5cm layer of organic mulch around the base of Thalictrum ‘Ankum’ in spring. This retains soil moisture, suppresses weeds, and provides nutrients as it decomposes.
Winter Protection: In colder months, mulch also helps protect the plant’s roots from frost.
Supporting the Plant
Staking: Due to its tall growth habit, Thalictrum ‘Ankum’ may need staking, especially in windy areas. Use discreet garden stakes or plant supports to keep stems upright and prevent damage.
Companion Planting
Thalictrum ‘Ankum’ pairs beautifully with shade-loving plants such as ferns, hostas, and astilbes. Its delicate flowerheads also contrast well with larger blooms like hydrangeas and echinaceas.

By planting Thalictrum ‘Ankum’ in partial shade with moist, well-drained soil and providing proper care, you can enjoy its ethereal blooms and graceful foliage throughout the growing season. This hardy perennial is an excellent choice for adding vertical interest and elegance to your garden, while also attracting pollinators like bees and butterflies.
