  • circleLife cycle

    The Masterwort 'Pink Sensation' (Astrantia major 'Pink Sensation') begins its life cycle with seed germination, typically in early spring, after which the seedlings develop into young plants with a basal rosette of leaves. With favorable light, moisture, and temperature conditions, the plant enters a vegetative stage where it produces more leaves and stems, growing steadily in size and vigor. After reaching maturity, the Masterwort 'Pink Sensation' produces distinctive pink pincushion-like flowers surrounded by papery bracts, generally in late spring to early summer. When the flowering period is over, usually in late summer, the plant sets seeds that are dispersed by wind, water, or animals. Following seed dispersal, the plant may enter a dormant phase, particularly in climates with cold winters, where the above-ground foliage dies back and the plant survives with its perennial root system. Each spring, the cycle recommences with new growth from the surviving roots, continuing the perennation of the Masterwort 'Pink Sensation'.

      Early Spring

    • The most popular method of propagation for Astrantia major 'Pink Sensation', or Great Masterwort, is by division. This should typically be done in the spring. To propagate by division, carefully dig up an established clump of Great Masterwort and gently separate the root mass into smaller sections, ensuring that each new segment has a part of the root system and some shoots. These divided sections can then be immediately replanted in moist, well-drained soil at the same depth they were originally growing. Make sure each new plant has adequate space to grow, and water them thoroughly after replanting to help establish the new divisions. It may take some time for the divisions to recover from the transplant shock and begin growing vigorously.
