Astrantia major Primadonna (Ruby Stars) Why is astrantia or masterwort (Astrantia major and other species) so little known? It has everything it takes to please the home gardener: beautiful star-shaped flowers in an interesting range of colors, a long blooming period, attractive foliage, excellent cold hardiness, ease of cultivation, reasonable availability in nurseries, etc. But it remains little known to the average gardener. Only the most informed gardeners seem to appreciate it and use it. (Replaces A. Ruby Cloud)
