Astrantia major 'Rubra'

great black masterwort

Product Image
Small, papery, plum-coloured, pincushion-like flowers surrounded by a ruff of wine-tinted bracts, are produced from June to August above deeply lobed, dark green leaves. Although an old cottage-garden favourite, this Astrantia works equally well in contemporary-style plantings - and its flowerheads will last well if cut for fresh or dried arrangements.

How to care for Astrantia major Rubra:

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.
