Mimulus Red Emperor

A vividly coloured, marginal pond-plant, Mimulus cupreus Red Emperor is a compact, herbaceous perennial of average vigour. The small, toothed, downy leaves are light green. Beautiful, trumpet-shaped bright scarlet-red flowers are borne June to August, and even into September, and are good for bees. Plant in a mesh basket to ⅓ of the water depth until established. Can also be grown as a marginal plant in reliably wet soil. Cut back flower-stems after flowering to prevent the plant’s energy going into seeds.
