Mystic™ is a new series of dahlias distinguished by striking dark foliage—deep mahogany to black—and a compact (18–36 inches), mounded form. 'Best Bett' (Mystic Spirit) has soft-apricot flowers with a dark eye. 'Kapow' (Mystic Dreamer) has pink-and-white candy-striped flowers. 'Scarlet Fern' (Mystic Desire) has scarlet-red flowers. 'Knockout' (Mystic Illusion) has bright-yellow flowers with dark-orange centers; it performed beautifully in trials at the J.C. Raulston Arboretum in Raleigh in 2007, in spite of drought conditions. Grow these dahlias in organically rich soil in full sun, or plant them in containers.
