meadow rue
From mid to late summer, airy sprays of tiny, long-lasting, rich-mauve, pompom-like flowers are carried on slender dark purple stems above clumps of fern-like, grey-green leaves.
Thalictrum delavayi 'Hewitt's Double' is a much sought-after double variety of meadow rue and is perfect for adding height to a range of planting applications. The delicate flowers can be prone to wind damage so these herbaceous perennials are best grown in a sheltered spot and supported by neighbouring plants or plant supports made from natural materials (see garden care notes below).

How to care for Thalictrum delavayi Hewitt's Double:
Thalictrum thrives in moist, well-drained soil in partial shade but can tolerate full sun if kept well-watered. Plant it in a sheltered spot to protect the tall, delicate stems from strong winds and stake using plant supports made from natural materials (e.g. hazel or birch) before the flowers appear.
Mulch annually with compost or well-rotted organic matter to retain moisture and enrich the soil. In autumn, cut back the flower stems to ground level to to tidy up and encourage healthy growth the following year. Regular deadheading during the season can also help prolong flowering.
Divide congested plants in early spring as new growth appears, though divisions may take time to settle.
