Thalictrum kiusianum

About this cultivar:

Thalictrum kiusianum, commonly called dwarf meadow rue or Kyoshu meadow rue, is a herbaceous perennial that is native to Japan and Korea where it is primarily found growing in moist woodland alpine areas. It typically forms a low-growing foliage mat of tiny, bronze-tinted, ternate green leaves. Tiny, starry, apetulous, lavender to pinkish-purple flowers bloom in fluffy many-flowered inflorescences (panicles). This is a slow grower, so be patient! All good things come to those who wait.

Specific epithet is derived from Kyoshu (southernmost of the four main Japanese islands) where this plant is native.

About this genus:

Thalictrum (t ha-ik-trum) is a genus of 120-200 species of herbaceous perennial flowering plants in the buttercup family (Ranunculaceae) native mostly to temperate regions. Once upon a time, the newborn infant was placed upon a pillow filled with Thalictrum to ensure a prosperous life. Thalictrum come from the Greek thallo which means to flourish, and it does, with elegant foamlike sprays that resemble Baby’s Breath, and rounded, finely cut, compound foliage.

Despite their common name of meadow-rue, Thalictrum species are unrelated to the true rue (family Rutaceae), but resemble its members in having the petiole twice or thrice divided. They are usually found in shaded or 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. It is most common in temperate regions of the world, twenty-two species are found in North America.

The leaves are commonly glaucous blue-green in colour. The flowers are small and are apetalous; in other words they have no petals. They have have numerous long stamens, often brightly white, yellow, pink or pale purple, and are produced in conspicuous dense inflorescences. In some species the sepals are large, brightly coloured and petal-like, but in most they are small and fall when the flower opens or soon after.

Thalictrum is tolerant of a wide range of growing conditions, depending on the species. However, they generally prefer an moist soil in sun or part shade.
