The Alum root 'Pluie de feu' forms a dense green carpet, mottled with grey. It produces beautiful, small bell-shaped red flowers from June to August. Planted as a uniform ground cover, associated with others Alum root varieties or ornamental grasses, it will adorn your borders and rockeries.
We recommend you plant 6 Alum roots per m². At the end of winter, it is necessary to cut back the foliage to encourage the growth of numerous new leaves.
