Astrantia major subsp. involucrata 'Shaggy'

masterwort

Product Image
With exceptionally long, green-tipped, white bracts that are often incurved in the middle and raggedly toothed towards the ends, 'Shaggy' produces larger than average flower heads for an Astrantia. In ideal conditions this masterwort will self seed freely if the faded flowers are not removed, but the resulting seedlings rarely come true to type.

How to care for Astrantia major subsp. involucrata Shaggy:

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 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.
