Best grown in loose, acidic, humusy, medium moisture, well-drained soils in full sun to part shade. Part afternoon shade is appreciated in hot summer climates. Prefers even moisture. Tolerates some soil dryness. Purchase plants in spring if available. Plants may be grown from seed started indoors about 6-8 weeks prior to the last spring frost date. Space plants 8†apart. Pinch main stems of young plants to stimulate branching. Deadhead spent flowers promptly to the extent practicable to extend bloom. Propagate by seed. Plants will easily reseed in the garden in optimum conditions.
