Among the most beautiful of flowers, dahlias are also edible! Most people dont realize that dahlias are a close New World relative of both sunflowers and Jerusalem artichokes. In addition to the petals, you also can eat the tubers (see recipe below). Although not all dahlia bulbs are tasty (some are quite bland), they have a range of flavors and textures that is hard to quantify: There are those with crunchy textures akin to water chestnuts or yacon (read Yummy Yacon for more information), and those with flavors ranging from spicy apple to celery root or even carrot. A lot depends on the variety and the soil in which the variety grew. Heirlooms such as Yellow Gem, introduced in 1914, are much more flavorful than the modern hybrids bred for huge, fluffy flower heads.
