Bring high drama to your summer borders with Organic Dahlia, Mexican Star. This hybrid cross with Chocolate Cosmos has star-shaped, dark chocolate-red flowers with ochre centres and looks lovely with other herbaceous perennials. Mexican Star (formerly known as Mexican Black) wafts a delicious chocolate fragrance over the garden and is a magnet to bees and butterflies. Growing instructions: Start indoors in pots in March or plant in the garden in May. Lift organic dahlias after the first frost and store the tubers over the winter. You can leave the tubers in the ground in sheltered areas if you protect them with a thick layer of compost or bracken.
