Astrantia major Sunningdale Variegated - Masterwort

Astrantia thrives in humus-rich, moist and well-drained soil in sunny, partially shaded, or even shady locations in warm climates. It requires little maintenance. Cut back the unsightly foliage before winter and remove faded flowers to encourage a second flowering. It self-seeds very easily, although not always reliably. Its only known enemies are slugs and snails.

Astrantia should be planted in spring or autumn, at a rate of 5 plants per square meter. To plant your young plant, prepare your soil to a depth of 20 cm (8in) by breaking up the soil well and adding fertiliser such as bone meal.  Position your plant, removed from its pot, by covering the top of the root ball with 3 cm (1in) of soil. Fill in the hole, tamp down, and water thoroughly to eliminate any air pockets. During dry weather, water regularly for a few weeks to facilitate root establishment. During wet weather, it is necessary to protect the young plants from slugs by using wood ash, slug repellent, or even beer! Each of these solutions is highly effective.
