Astrantias are superb perennials for growing under trees, on a stream bank or in a moist border. They prefer moist soils but will tolerate drier conditions as long as the plants are mulched.

Astrantia major subsp. involucrata 'Gill Richardson' is a gorgeous variety with tiny red flowers surrounded by false petals called bracteoles.

Resistant to slugs and snails. Prolific self seeder so deadhead regularly to prevent this if you don't want them to colonise.
