  • circleLife cycle

    Great Masterwort 'Rosa Lee' begins its lifecycle as a seed which germinates in early spring, preferably in moist, well-drained soil with partial to full sun exposure. Upon germination, the seedling emerges and develops into a basal rosette of deeply lobed, dark green leaves. As it matures during the spring and early summer, a flower stalk arises from the rosette, sporting the plant's distinctive pincushion-like blooms that are pink to purple in color, surrounded by a ruff of bracts. After flowering, typically from June to August, the plant sets seed which can be dispersed by wind or wildlife. In the fall, the above-ground foliage dies back with the onset of colder temperatures, while the roots remain dormant through winter. With spring's arrival, the plant resumes growth, repeating its cycle, and it may also propagate by division as it forms clumps over time.

      Spring to early summer

    • Propogation: Astrantia major 'Rosa Lee', commonly known as Masterwort, can be propagated by division, which is the most popular method for this perennial plant. The ideal time to propagate Masterwort by division is in the spring or early autumn when the plant is not in active bloom. To do so, carefully dig up the entire plant, ensuring you have a good amount of the root system. Then, using a sharp spade or knife, divide the plant into smaller sections, each with a section of roots and several shoots. Replant these divisions promptly into well-draining soil at the same depth they were growing before and water them thoroughly. With proper care, the new plants will establish themselves and grow, flowering in the following seasons. Division helps not only to propagate Masterwort but also to rejuvenate older clumps that may become woody or less vigorous over time.
