Chocolate Cosmos is one of our favorite seasonal plants. It blooms non-stop from June to frost with copious single deep red/black/mahogany flowers that have the special fragrance of dark chocolate. Forms colonies in well drained, rich soil with regular summer water. Forms a tuberous root stock and may be lifted and stored like a Dahlia in autumn. Otherwise a great tender perennial for containers, borders. Fantastic cut flower. Mexico.
