In the garden

Thalictrum diffusiflorum is a perennial member of the Ranunculaceae from south-west China, traded as diffuse-flowered meadow rue. It comes into flower in the UK between June and August, offering a mid-summer display suited to cooler, damper sites rather than dry, exposed banks. Plant in partial shade or full sun on a well-drained, loamy soil that remains moist and leans neutral to slightly acidic in pH. North-, east- or west-facing positions are appropriate, and the species prefers sheltered to semi-exposed exposures rather than fully exposed sites. Work organic matter into the planting hole to improve moisture retention without creating waterlogging; the combination of good drainage and consistent moisture is important for reliable growth. Use Thalictrum diffusiflorum in mixed borders, woodland gardens or naturalistic plantings where a summer-flowering perennial is required. It sits well where other moisture-tolerant perennials provide structure and can take sun if the soil does not dry out. Handle with care: contact with the foliage may irritate the skin, so wear gloves and other protective equipment during planting and maintenance.
