  • circleLife cycle

    Astrantia 'Moulin Rouge', also known as Masterwort 'Moulin Rouge', begins its life as a seed, sown in well-drained soil in the spring or autumn. It then germinates, typically within a few weeks, depending on soil temperature and moisture levels. Following germination, seedlings develop into juvenile plants with a rosette of leaves at the soil surface. As the plant matures, it develops a strong root system and begins to produce characteristic branched stems with deeply lobed, dark green leaves. During the flowering stage in early to mid-summer, it produces striking, pincushion-like burgundy flowers that are highly attractive to pollinators. After the flowering period, seeds are produced and dispersed, completing the cycle, while the plant itself typically dies back to the ground in winter and re-emerges in spring.

    • The common name for Astrantia 'Moulin Rouge' (PBR) is Great Masterwort, and the most popular method of propagation for this plant is by division. This method is usually carried out in the early spring or fall. To propagate by division, carefully dig up the plant, making sure to keep a good amount of the root system intact. The root clump can then be gently pulled apart into smaller sections, ensuring that each new section has a portion of the root system attached. These divisions can then be replanted in well-draining soil, ideally in a location that receives partial shade and maintains consistent moisture. Water the new plantings thoroughly to help establish them. Division helps to create new plants that are true to the parent's characteristics and is generally a quick and effective way to increase your stock of Great Masterwort.
