Astrantia major

Great Masterwort

Outstanding Qualities

A loose open growing perennial with unusual airy pin cushion–like flowers in late spring through summer, masterwort is a great perennial for blending and mixing into the garden. The odd blooms have a papery ruff of bracts (false petals) surrounding a dome of tiny flowers. Most plants flower white with steaks of apple green or white blushed pink. If you want a stronger color or uniformity amongst the planting, one of the many excellent named cultivars should be planted.

Culture Notes

Masterwort thrives in rich well drained soil, but will tolerate a wide range of soil types including sand and clay. Plant this perennial in full sun to light or open shade and provide regular watering during dry weather. Although it will tolerate dappled shade the flowering will be sparse. Once the first flush of flowers has finished either enjoy the dry seed heads or cut it to the ground to minimize seedlings and to enjoy a second flush of late season bloom.
