The large and textural bi-coloured leaf, deep green with eye-catching chocolate centres, of this hardy pelargonium is a feature that makes it one of the main players in the Heronswood evergreen border. Growing as a neat, medium-sized shrub, it provides a lush green foil for more showy summer perennials and adds good year-round structure. ‘Chocolate Mint’, with its striking, mint-scented, evergreen foliage, is a useful link in any planting scheme.
