During the winter months, you can reduce watering as the plant's water needs decrease.
Masterwort thrives in partial shade to full sun. The ideal location would provide morning sunlight and afternoon shade, ensuring that the plant gets enough light without being exposed to the harsh midday sun. Filtered sunlight beneath open canopies of trees is also suitable for this plant.
Masterwort prefers temperate conditions and can typically withstand temperatures as low as 25°F and as high as 75°F. The ideal growing temperature range for this plant is between 65°F and 70°F. Protection from extreme cold and frost is necessary to prevent damage to the plant.
Masterwort benefits from pruning to remove spent flower stems and encourage bushier growth. Prune immediately after flowering to tidy up the plant and potentially stimulate a second bloom. The best time for pruning is late summer or early fall, just as the flowers start to fade.
Masterwort (Astrantia major 'Primadonna') thrives best in a rich, moist, well-draining soil with a pH of 5.8 to 6.5. A good soil mix for masterwort would contain garden loam, compost, and a small amount of sand to ensure drainage. Mulching can help retain moisture and provide nutrients as it decomposes.
Masterwort typically does not require frequent repotting and can be left undisturbed for several years. Repot it only when you see signs of overcrowding or the plant outgrows its current container, which might be every 3-5 years, depending on its growth rate and conditions.
- Humidity & Misting

- Life cycle
The great masterwort 'Primadonna' begins its life cycle with seed germination, normally in early spring after the last frost when the soil is moist and temperatures are mild. Seedlings emerge and develop into a rosette of leaves as they establish a root system. As the plant matures, it sends up flowering stems in late spring to summer, displaying intricate, starry flowers that attract pollinators. After flowering and pollination, seeds develop and are dispersed in late summer or fall, sometimes with the help of animals or wind. The plant typically dies back to the ground in winter, surviving the cold months as a dormant rootstock or clump. With the return of warmer weather in spring, the great masterwort resumes growth from the existing rootstock, completing its perennial cycle.
Late spring to early summer
Propogation: The most popular method of propagating Astrantia major 'Primadonna', commonly known as Masterwort, is by division. This is typically done in the spring or early fall when the plant is not in active bloom. To propagate by division, carefully lift the entire plant from the ground using a garden fork, trying to keep the root ball intact. Once out of the ground, use a sharp knife or spade to divide the root ball into smaller sections, ensuring that each section has several growth points or shoots. Replant the divisions immediately at the same depth they were growing previously, spacing them about 12 to 15 inches (30 to 38 centimeters) apart to allow room for growth. Water the new plants thoroughly to help establish them. Through this method, Masterwort can be effectively multiplied, maintaining the health and vigor of the parent plant.
