'Claret' is one of the darkest-flowered astrantias, with deep, ruby-red pincushion-like flowers with a ruff of longer bracts than many other varieties. The leaves are pretty too, being deeply lobed and dark green. Although it is an old cottage garden favourite, this Astrantia works equally well in contemporary-style plantings. Use it towards the front of a sunny, reliably moist border, where the flower colour can be fully appreciated.
