Sparkling silver inflorescences.
Native to the mountain slopes of South-East Asia (China, Japan, Korea) Spodiopogon sibiricus (frost grass, Siberian greybeard or silver spike) is a highly decorative grass: 1.2 m in height, sparkling silver inflorescences, flamboyant red autumnal colouring.
It prefers partial shade or, if planted in the sun, soil that is not too dry.
Either plant on its own or in a bed. Cut back the clumps at the end of winter.
