Early Meadowrue

Thalictrum dioicum (tha-LIK-trum dy-oh-EE-kum)

Family: Ranunculaceae Native Herbaceous (1-3 ft)

Early Meadow Rue is an easy to grow native perennial wildflower in the Ranunculaceae (buttercup) family with lacy gray-green compound leaves which resemble the genus Aquilegia (columbine) and this plant is often confused with Columbine or the Adiantum genus (Maidenhair Fern). It's scientific name comes in part by dioicum which is Greek meaning "of two houses" referring to the flower sexes being on different plants. It blooms in early spring, just as the leaves are coming out on the trees, which accounts for its common name. It is found naturally in seepages and moist forests. This plant is pollinated by the wind. Plant in average to rich well-drained soil in the full sun to dappled or partial shade. Its gray-green leaves provide a great backdrop to other later flowering perennials, and it looks attractive in a border front, in a meadow or cutting garden or naturalized area of the landscape. It is heat and humidity sensitive and dies back in the middle of summer. After the plant dies back, low basal leaves develop during the fall. Plant in a naturalized area or meadow. Insects, Diseases, and Other Plant Problems: No serious problems. Older plants may need to be staked to stay upright.
