Outstanding Qualities

This unusual species of masterwort has lovely star shaped flowers that are white and green in bud and open to a soft, but vibrant pink. The blooms are larger than other Astrantia and are held high above the bright green foliage. This perennial will gently self sow around the garden but will not take over making it great for mixing and weaving through the landscape.

Culture Notes
This unusual masterwort will thrive in rich well drained soil, but will tolerate a wide range of soil types including sand and clay. Plant it in full sun to light or open shade and provide regular watering during dry weather. Although it will tolerate dappled shade the flowering will be sparse. Once it has finished flowering, either enjoy the dry seed heads or cut it to the ground to minimize seedlings. The flowers are taller and more lax on this species and benefit from mixing with other perennials to help support the stems.
