Dianthus stays cheerful through our cool spells and even light frosts, making it one of the few annuals that actually toughens up as temperatures drop. 'Rockin Pink Magic' brings reliable colour into autumn and winter, when most of the garden has gone quiet.

Plant in a sunny spot with decent drainage and you'll get weeks of blooms for minimal fuss. Deadhead spent flowers to keep them coming, or let them go and enjoy the cottage-garden look.
