Hewitt's Double Meadow Rue

Hewitt's Double Meadow Rue (Thalictrum delavayi 'Hewitt's Double')

Hewitt's Double Meadow Rue brings a light, airy look to the garden with floating flower clouds that soften borders without adding bulk. It is an easy way to add height and movement behind shorter perennials, especially in part shade where color can feel limited. The effect is graceful rather than stiff, and it looks natural in both designed borders and woodland-style plantings. Plant it where you want a long-season haze of bloom and a refined, ferny backdrop.

Distinctive Features

This cultivar produces frothy sprays of fully double, pompom-like flowers in lilac to mauve tones held on slender, often purplish stems. Bloom typically runs from mid to late summer into early fall, creating a lingering, cloudlike display above the foliage. The leaves are finely divided and fern-like, giving the plant a delicate texture even when it is not in flower. In good soil with steady moisture, it forms an upright clump that sways gently and adds an elegant vertical layer to mixed plantings.

Growing Conditions

• Sun: Full sun to partial shade, with best performance in partial shade or sun with consistently moist soil.
• Soil: Rich, humus-forward, well-drained soil that holds moisture, and avoid sites that dry hard in summer.
• Water: Moderate, keep evenly moist during active growth and flowering, especially in warmer weather.
• USDA Zones: 5 to 7.
• Mature Size: About 3 to 4 feet tall and 2 to 3 feet wide.

Ideal Uses

• Focal Point: Plant a small group behind mid-height perennials so the flower clouds become a late-season focal point above the border.
• Back Border: Use to add airy height that does not feel heavy or block views through the garden.
• Woodland Gardens: Tuck into bright shade where the ferny foliage and soft bloom blend naturally with shade companions.
• Cut Flowers: Harvest flowering stems for bouquets that add a light, lace-like texture.
• Companion Planting: Pair with hostas, astilbes, ferns, and hydrangeas for layered texture and a longer season of interest.

Low Maintenance Care

• Staking: Support in windy sites or let nearby plants provide natural bracing for the tall stems.
• Watering: Water during dry spells to prevent stress and keep flowers and foliage looking fresh.
• Mulching: Mulch to conserve moisture and maintain cool, even soil conditions.
• Cleanup: Cut back stems in late fall or late winter before new growth begins.
• Division: Divide clumps every few years if vigor slows or if you want to increase your planting.
