The plant can also tolerate full sun but cannot withstand harsh, direct sunlight. Therefore, it is essential to provide the plant with adequate sunlight, which can enhance its growth and overall health.
Temperature Requirements
The Steel's meadow rue prefers cooler temperatures, thriving best in USDA hardiness zones 4-7. The ideal temperature range for the plant is between 60°F-70°F (15.6°C-21.1°C). It cannot tolerate extreme heat and becomes dormant during hot summer months when temperatures exceed 85°F (29.4°C). Therefore, it is essential to avoid exposing the plant to excessive heat to ensure its optimal growth.
Soil Requirements
The Steel's meadow rue requires fertile, well-draining soil. It can thrive in various soil types, including clay, loamy, or sandy soils. However, the plant prefers slightly acidic to neutral soil pH levels, ranging from 5.5 to 7.0. Additionally, the plant requires consistent soil moisture levels, but the soil must not be waterlogged as it can lead to root rot. To ensure optimal growth, it is best to plant Thalictrum steeleanum Boivin in soil that is rich in organic matter.
Cultivation
Thalictrum steeleanum Boivin, commonly known as Steeles' meadow-rue, is a herbaceous perennial plant that belongs to the buttercup family Ranunculaceae. This plant is native to North America and can be found growing in moist meadows and woodlands. The recommended cultivation method for Thalictrum steeleanum Boivin is the division of the root clump. It is best to divide the plant in the fall during its dormancy period. After dividing, replant the segments in moist, well-drained soil. This plant thrives in partial shade to full sun, making it ideal for shady areas of the garden.
Watering Needs
Thalictrum steeleanum Boivin requires regular watering to promote healthy growth. This plant prefers moist soil and can tolerate occasional flooding. However, it is important not to overwater the plant as this can lead to root rot. Water the plant deeply once a week and adjust the watering schedule based on the weather condition. During hot and dry weather, it is best to increase the frequency of watering.
Fertilization

Propagation of Thalictrum steeleanum Boivin
Thalictrum steeleanum Boivin, also known as Steele's Meadow-Rue, is a herbaceous perennial plant that belongs to the family Ranunculaceae. It is native to North America and can be found in moist meadows, stream banks, and open slopes. Propagation of Thalictrum steeleanum Boivin is possible through various methods, including seeds, division, and cuttings.
Propagation through seeds
The most common method of propagating Thalictrum steeleanum Boivin is through seeds. The plant produces small, black seeds that are easily collected in the fall when they are ripe. Seeds should be sown immediately, either in the fall or in the spring after stratification. Seeds can be sown in containers or directly in the garden. Germination should occur within two to three weeks.
Propagation through division
Propagation through division is another effective method for Thalictrum steeleanum Boivin. The plant can be divided in the spring or fall, and each divided clump should have several buds. To divide the plant, dig up the clump and cut through the root ball with a sharp knife or spade. Replant each division immediately, making sure to keep the soil moist until new growth appears.
Propagation through cuttings
Propagation through cuttings is also a possibility for Thalictrum steeleanum Boivin. Softwood stem cuttings can be taken in the spring and early summer when the plant is actively growing. Cuttings should be about 6 inches long and should include several sets of leaves. Remove the lower leaves and dip the cut end in rooting hormone before planting in a container filled with a well-draining potting mix. Keep the soil moist and place the container in a shaded area until new growth appears.
Disease and Pest Management for Thalictrum steeleanum Boivin
