Noteworthy CharacteristicsPolyanthas are celebrated for their profuse clusters of ever-blooming single or double small flowers. While the blossoms usually are not fragrant, they are produced in waves from late spring or early summer until fall. They are compact and disease-resistant, making them ideal for borders or hedges and for growing en masse as a ground cover. 

CareGrow in fertile, moist, well-drained soil in full sun or partial shade. Provide good air circulation, and remove fallen leaves to help prevent disease. In late winter or early spring, prune hard (back to 10–18 inches) and reduce side shoots to two or three buds. To renovate, prune one in three stems close to the base.

PropagationTake softwood cuttings when bloom initiates in spring to summer; take hardwood cuttings in fall.
