Dahlia ‘Duet’ produces profuse and spectacular bicolor flowers, an elegant mix of dark wine toward their heart against crisp white at their tips. The double flowers, up to 6 to 8 in. wide, are borne atop strong 3 ft. stems flowering from summer until frost and provide an amazing focal point in the garden or vase. Plant the tuberous roots in full sun although light shade will be welcomed in summer heat. Deadhead spent flowers to promote growth of additional flower buds. Provide consistent moisture so the soil does not dry out.
