For radiant colour from spring to midsummer, few plants match the staying power of helianthemums. Often known as the Rock Rose, these alpine species are particularly hardy, versatile and trouble free., leaving you ample time to simply enjoy their beauty. Bright saucer-shaped flowers inject colour into rock gardens and herbaceous or mixed borders and look great en masse on a sunny bank.
As if that's not enough, they reward you with a second flush of blooms in late summer!
