Chinese Meadow Rue Thalictrum delavayi 'Hewitt's Double' (d)
ABOUT
The Thalictrum delavayi 'Hewitt's Double', commonly known as the Chinese meadow rue, is a perennial plant noted for its delicate and airy appearance, which brings a touch of whimsy to gardens. Its distinguishing feature is the profuse, fluffy, pom-pom like flowers that boast a soft lilac to mauve color. These blooms display numerous slender, petal-like structures layered on top of each other, giving them a full, ruffled look that is quite distinct from the species type which usually has simpler, more understated flowers. The foliage of Chinese meadow rue is also attractive, composed of fine-textured, blue-green leaves that resemble those of a Columbine or a Maidenhair fern. They are typically divided into leaflets that are further subsectioned into smaller leaflets, creating a compound leaf with a lacey, fern-like quality. This delicate foliage provides an excellent backdrop for the showy double blossoms, which float above the leaves on thin, wiry stems, creating a cloud of color. The combination of the ethereal flowers and elegant foliage adds a light, graceful presence to any planting area where they are allowed to thrive.

WaterThe Chinese meadow rue (Thalictrum delavayi 'Hewitt's Double') prefers moist, well-drained soil, which means it should be watered regularly to maintain consistent soil moisture but not waterlogged. Typically, during the growing season, watering once a week with approximately 1 gallon of water per plant is ideal, though this may need to be adjusted depending on weather conditions and soil type. During hot, dry spells, more frequent watering may be necessary. Reduce watering in the winter when the plant is dormant. Always check the top inch of soil for dryness before watering to avoid overwatering.
LightChinese meadow rue thrives best in dappled sunlight or partial shade. It can tolerate full sun in cooler climates, but in warmer regions, protect it from the harsh afternoon sun. A spot that receives morning sunlight with shade in the afternoon would be ideal for the optimal growth of this plant.
TemperatureChinese meadow rue does best in temperatures ranging from 60 to 75 degrees Fahrenheit; however, it can tolerate temperatures down to about 50 degrees and up to approximately 85 degrees Fahrenheit. It's important to avoid placing it in locations where it could be exposed to temperatures below freezing or extreme heat.
PruningPrune the Chinese meadow rue after flowering finishes to tidy the plant and prevent self-seeding if not desired. Cutting back the stems to the ground in late fall or early winter after the plant has gone dormant helps to promote vigorous growth in the spring. Pruning is typically required once per year.
CleaningAs needed
SoilChinese meadow rue prefers a fertile, well-drained soil enriched with organic matter. The ideal soil pH for this plant is slightly acidic to neutral, ranging from 6.0 to 7.0. A soil mix of loam, compost, and a portion of perlite or sand to ensure good drainage would be most beneficial for this plant's growth.
RepottingChinese meadow rue does not require frequent repotting and can thrive in the same pot for several years. However, if you notice the plant has outgrown its current container or the soil has become compacted, repotting in spring every 3-4 years is advisable.
Humidity & MistingChinese meadow rue does well in average room humidity. However, it appreciates higher humidity levels, which mimic its natural habitat. Aim for a humidity level of around 50-60% for optimal growth conditions.
Suitable locationsIndoor
Provide bright, indirect light and keep soil moist.

Life cycleThalictrum delavayi 'Hewitt's Double', commonly known as Chinese meadow rue, begins its life cycle when the seeds are sown in spring or summer, germinating in a cold frame or under light shade. The emerging seedlings develop into young plants with delicate foliage, and it is often necessary to overwinter these young plants in a protected environment to ensure their survival. As they enter the vegetative growth stage in the second year, the plants establish strong root systems and form clumps of airy, fine-textured leaves. Upon reaching maturity, usually in the second or third year, they produce tall, erect stems with fluffy, lavender-to-purple flowers with double petals in early to mid-summer. After flowering, the plant sets seed, which can be collected for propagation, or if left alone, may self-seed under favorable conditions. Once the growing season is over and the colder temperatures set in, the plant dies back to the ground, entering dormancy before reemerging in the spring to start the cycle anew.
PropogationPropogation time
Late spring-early summer
Thalictrum delavayi 'Hewitt's Double', commonly known as Chinese meadow rue, can often be propagated by division, which is a popular method for many garden perennials. Division should be carried out in the spring as new growth appears. To propagate by division, carefully dig up the entire plant, ensuring a good amount of roots are included. Using a spade or a sharp knife, split the plant into smaller sections, each with several shoots and a portion of the root system. Replant the divisions at the same depth they were growing at previously, spacing them about 18 to 24 inches (approximately 45 to 60 centimeters) apart to allow for growth. Water the new divisions thoroughly to help establish them. This technique allows gardeners to quickly multiply their plants while maintaining the characteristics of the 'Hewitt's Double' cultivar.
