masterwort 'Florence'


Astrantia major 'Florence' is a perennial plant notable for its distinctive and charming flowers. The blossoms are composed of a pincushion-like central cluster of tiny, delicate flowers surrounded by a starry collar of bracts, which give them a somewhat lacy appearance. These bracts range from pale pink to a richer, mauve-pink hue, creating a soft contrast against the deeper tones of the inner flowers. The foliage of 'Florence' is equally attractive, with deeply lobed, palmate leaves that have a serrated edge. These leaves are lush and typically a bright green color, forming an attractive mound that cradles the flower heads gracefully. The leaves generally remain attractive throughout the growing season, providing a nice backdrop for the floral display. Adding to its visual appeal, Astrantia major 'Florence' has sturdy stems that hold the flowers well above the clump of foliage, giving them an airy, floating effect within a garden setting. The plant's beauty and structure make it an excellent choice for borders, cottage gardens, or as part of a naturalized planting, where its unique flowers and pleasing foliage can be admired. Its flowers are also prized for their longevity in cut-flower arrangements, bringing a touch of wildflower charm to bouquets.

  • water dropWater

    Great Masterworts require consistent moisture, especially during dry spells, to keep their soil evenly moist. It's best to water these perennials about once a week with enough water to saturate the soil to the root level, which can mean roughly 1 to 1.5 gallons depending on the size of the plant and environmental conditions. Avoid overhead watering to reduce the risk of leaf diseases; instead, apply water directly at the base of the plant. During particularly hot or windy weeks, you might need to increase the frequency to ensure the soil doesn't dry out. Conversely, reduce the amount of water during cool, wet periods to prevent waterlogging.

  • sunLight

    Great Masterworts thrive best in partial shade conditions, where they receive some sunlight but are protected from the harsh afternoon sun. An ideal spot is under the canopy of open trees or on the north side of a building where they can enjoy sunlight during the cooler parts of the day. However, they can also tolerate full sun in cooler climates, as long as they are provided with ample moisture.

  • thermometerTemperature

    Great Masterworts are hardy and can withstand temperatures as low as 0°F and as high as about 85°F without damage. The ideal temperature range for these plants is between 60°F to 75°F. They perform well in temperatures common to many temperate regions and should be protected from extreme heat or frost to maintain their health and blooming capability.

  • scissorsPruning

    Prune Great Masterworts to encourage bushier growth and more blooms. Removing spent flowers, a practice known as deadheading, will promote continuous blooming throughout the season. Cut the stems back to the base in late fall or early spring before new growth begins. Generally, annual pruning is sufficient to keep the plant healthy and aesthetically pleasing.

  • circleLife cycle

    The Astrantia major 'Florence' (PBR), commonly known as Masterwort 'Florence', begins its life cycle as a seed which germinates in spring, given damp and cool conditions. Seedlings develop into a rosette of palmate leaves, and as the plant matures, it forms a clump with multiple stems. The first blooms may appear in late spring to early summer, presenting pincushion-like flowers surrounded by bracts, in shades of dusky pink. After flowering, seeds are produced and can be dispersed, potentially leading to new plants if conditions allow. Over winter, the plant may die back to the ground in colder climates, conserving energy in its root system. In spring, new growth emerges from these roots, continuing its perennial life cycle.

    • Propogation time

      Spring to early summer

    • Astrantia major 'Florence', also known commonly as Great Masterwort, is typically propagated by division. The best time to propagate this perennial is in the spring or early fall when the plant is not in active bloom. To propagate by division, carefully lift the entire plant with a shovel, ensuring a good portion of the root system remains intact. Gently tease apart the plant's clumps into smaller sections, each with roots and shoots. Replant the divided sections at the same depth they were growing at previously, spacing them about 12 to 18 inches (approximately 30 to 45 centimeters) apart to allow room for growth. Water the new divisions thoroughly to help establish them. This method of propagation helps to rejuvenate old clumps while increasing the number of plants in your garden.
