Skunk Meadowrue

Thalictrum amphibolum (tha-LIK-trum am-fee-BO-lum)

Family: Ranunculaceae Native Herbaceous

Waxy Meadowrue is a perennial wildflower in the Ranunculaceae (buttercup) family that grows 3 - 7' tall in the eastern US and Canada. It has a thick central stem that is green or slightly reddish purple with short hairs. The stem branches occasionally. It can be found in streambanks, edges of pond or forests, thickets, meadows, prairies, and roadsides. Plant it in moist to slightly dry conditions, and partial to full sun. This plant usually grows in fairly typical garden soil, such as a rich loam or clay loam. The height of a plant can vary considerably on fertility of the soil, moisture conditions, and maturity. Very rapid growth in the spring and only blooms for about 3 weeks. This species of Meadowrue appears to tolerate full sun and drought conditions better than most. However, it will still die back in the heat of the summer but will grow new basal leaves in the fall. You won't find many places to purchase this plant, possibly because of the foul-smelling leaves when places do sell the Purple Meadowrue as it is so similar and has no smell. However, it is easily grown from seed. Also, it is rhizomatous, where you can divide the plant when it is dormant in the spring. Plant in a meadow or slope of a bank, near a pond or in a woodland or other naturalized area. Quick ID: Each leaflet has glandular hairs on the underside which gives it a waxy appearance that will glisten when they are exposed to sunlight. The margin of each leaflet turns downward slightly. The leaves have a foul smell when crushed (skunk-like). Insects, Diseases, and Other Plant Problems: No significant problems.
