Description
Winter hardy to USDA Zones 7-10 where plants are best grown in rich, humusy, acidic, moist, somewhat gritty, well-drained soils in full sun to part shade. Best sited in sunny areas with some afternoon part shade.. Mulch helps plants retain soil moisture in summer. Plants generally produce best flowers and leaf colors in sunnier locations. Little pruning is needed other than what is necessary to maintain size and shape.
