Astrantia 'Superstar' (PBR)
masterwort
Bright, airy flowerheads bring a lifted, elegant feel to summer borders, with soft green-white tones that seem to float above the planting. The blooms sit on slim, wiry stems, each one forming a neat pincushion shape surrounded by a delicate ruff of pointed bracts.
Strongly clump-forming and reliable, Astrantia ‘Superstar’ builds into a tidy mound of deeply divided green foliage, then sends up wave after wave of long-lasting flowers from early summer well into autumn. It slips easily into mixed borders, cottage-style planting or more modern schemes, blending without fuss while still adding structure and movement.
Use it where you want gentle height and repeated interest through the season, especially in part-shaded spots where it stays fresh for longer. In gardens that are well cared for, it often rewards with a second flush later in the season, extending the display right when many other perennials are starting to fade.

How to care for Astrantia Superstar (PBR):
Incorporate plenty of organic matter when planting and water well in dry weather, especially newly established plants.
Lift and divide large clumps in early spring and apply a generous 5-7cm (2-3in) mulch of well-rotted manure or garden compost around the plant. Divided specimens may take some time to establish since they don't like having their roots disturbed.
Astrantia thrive in consistently moist soils and perform best in cool, partially shaded summer conditions.
