"The Gallery Dahlia Singer, 'Dahlia', a spring planted tuberous root, produces masses of rich, dark red colored double flowers that are up to 5 inches across. The Gallery Dahlia start blooming in early summer and produce large amounts of flowers on a well branched plant. Dahlia's are ideal for cut flowers, borders, containers, and window boxes. They tend to bloom for long periods, and few plants offer as much variety and showy flowers as the Dahlia. They do best in well drained, humus rich soils."
