Thalictrum
 

Thalictrum is a genus of about 130 species of flowering plants in the family Ranunculaceae. The common name is meadow-rue. They are not related to the rues (family Rutaceae).

They are perennial herbaceous plants, growing to 0.5-2.5 m tall depending on the species.

Habitat

They are usually found in shaded, damp locations, with a sub-cosmopolitan range throughout most of the Northern Hemisphere and also south to southern Africa and tropical South America, but absent from Australasia.

Leaves and flowers

The leaves are alternate, bipinnately compound, commonly glaucous blue-green in colour.

The flowers are small and apetalous (no petals), but have numerous long stamens, often brightly white, yellow, pink or pale purple, and are produced in conspicuous dense inflorescences. In some species (e.g. T. chelidonii, T. tuberosum), the sepals are large, brightly coloured and petal-like, but in most they are small and fall when the flower opens or soon after.

Food plants

Thalictrum species are used as food plants by the larvae of some Lepidoptera species including Setaceous Hebrew Character.
