Great Masterwort Overview

Astrantia major is a herbaceous perennial also known by the name masterwort. It is widespread across Europe and was introduced to the British Isles in the 16th Century. Commonly found in mountain meadows, grasslands, forests & clearings and close to streams. It produces palmately-divided, 3-5 lobed, green leaves in the spring. These are followed by branching stems bearing small pale white-pinkish bracts surrounding white-green flowers. These appear in early to midsummer and are attractively veined. Suits planting in flower beds and borders in a cottage or informal garden setting.
