The Astrantia Snow Star PP#12697, 'Astrantia', is a lovely variety from Future PlantsĀ®. It is pale greenish white, with the light scent of anise. It grows to a height: 30". It is Plant Patent Protected. Asexual Propagation Prohibited. These long flowering perennials are ideal when planted in borders or along streams. It makes an excellent cut flower. Astrantias thrive in moist, humus-rich or heavy clay soil. With good soil moisture, astrantias can be planted in full sun. To stimulate more blooms, remove old flowers. Blooms last long - late spring to early summer, and the bracts usually remain attractive well after bloom. Like little pincushions, their abundant blooms float above rosettes of mid-sized, deeply lobed, bright green leaves.
