Dahlias were known only to the Aztecs and other southern North American peoples until the Spanish conquest, after which the plants were brought to Europe. The tubers of some varieties are of medicinal and dietary value to humans because, in common with species of Inula and many other flowering plants, they use inulin, a polymer of the fruit sugar fructose, instead of starch as a storage polysaccharide.
