Type: Herbaceous perennial
Family: Apiaceae
Zone: 4 to 7
Height: 2.00 to 3.00 feet
Spread: 1.50 to 2.00 feet
Bloom Time: May to July
Bloom Description: Dusty pink
Sun: Part shade
Water: Medium to wet
Maintenance: Medium

Best grown in organically rich, medium 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. a cultural preference that unfortunately does not fit the profile of a typical St. Louis area summer where the plant often labors. In optimum growing conditions, plants may spread to form large clumps by both stolons and self-seeding.

'Buckland' is sterile and will not self-seed.

Noteworthy Characteristics

Astrantia, commonly called masterwort or great masterwort, is an umbelliferous, stoloniferous, clump-forming perennial which typically grows 2-3' tall. Flower is a domed umbel of greenish-white or pink florets subtended by a showy ruff of papery, petal-like, greenish or pinkish tinged involucral bracts which extend beyond the flower. Medium green leaves are palmately cut into 3-7 (usually 5) toothed lobes. Leaves appear primarily in basal clumps, with smaller versions on the stems. Long late spring to early summer bloom. Bracts usually remain attractive well after bloom.

Genus name comes from a Greek word astron meaning star in reference to the flower head shape or from magistrantia (derived from the Latin word magister meaning master or teacher).

'Buckland' typically grows to 24-30” (less frequently to 36”) tall. It is reportedly a hybrid of A. major x A. maxima. Each flower features a pincushion-like umbel of dusty pink florets subtended by a showy ruff of papery, petal-like, silvery-green involucral bracts. The bracts usually remain attractive well after bloom. Flowers bloom from late spring to early summer on stems rising well above the basal clump of foliage.


No serious insect or disease problems. Slugs are occasional visitors.


Part shade areas of perennial borders, open woodlands, path edges, stream/pond margins or wild/cottage gardens. Performs well in moist sun-dappled areas below open trees. Excellent for dried flower arrangements.
