Astrantia (Great Masterwort) Major “Rosea”

Astrantia, “Rosea” is a charming cottage garden flower. Beloved by butterflies. Unusual delicate star-like blooms that can be used as a fresh cut flower. The flowers are dense 2-3″ diameter domes of tiny florets, backed by stiff, petal-like bracts, usually referred to as a ‘collar’, all held above the foliage on wiry stems. Interesting, complex, long-lasting flowers, prized by flower arrangers but also perfectly at home in the cottage garden.

The dark green, lobed leaves form an attractive mound. Exotic and yet very easy to grow. A fabulous bloomer. Very effective when in mass. The optimum site for Astrantia would be partial shade with a well-drained soil. Looks nice in an English garden setting as a border plant.

General Information +

General Characteristics: Keep plant deadheaded for a longer bloom period. Well-drained but not dry soils. These will generally do well in full sun in the north, but do not like the heat and humidity of the deep south, even in part shade. They are quite capable of coping with bad weather: severe winter cold, long snow-covered periods and the heat, and sometimes dryness, of summer. Excellent, long-lasting cut flowers. Masterwort (sometimes also called great masterwort) is a clump-forming perennial which typically grows 2-3' tall. The flower is a domed umbel of greenish-white or pink florets supported by a showy ruff of papery, petal-like, greenish or pinkish-tinged rosette bracts which extend beyond the flower. Leaves are palmately cut into 3-7 (usually 5) toothed lobes. Leaves appear primarily in basal clumps, with smaller versions on the stems. Bracts usually remain attractive well after bloom.

Planting/Care Instructions +

Planting Instructions: Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. Best grown in organically rich, medium wet to wet, well-drained soils in part shade. Soils must be kept uniformly moist and not allowed to dry out. Best performance occurs in cool summer climates where night temperatures consistently dip below 70 degrees F. In optimum growing conditions, plants may spread to form large clumps.

Pests or Diseases: They do not readily succumb to any pests in a major way, so they are sure to reward you with a pleasing display.
