Noteworthy CharacteristicsA popular cultivar with slightly larger flowers on a more compact plant than the species. Foliage is evergreen to semi-evergreen in the southern part of its growing range. Use in hedges, shrub borders, foundation plantings, or en masse. May be susceptible to winter damage, which will not affect flowering.

CareProvide full sun to part shade and moist but well-drained, rich, sandy soil. 'Sunburst' will tolerate some drought. Mulch in winter.

PropagationSow seed in a cold frame in autumn. Divide in spring or autumn. Take softwood cuttings in late spring; greenwood or semi-ripe cuttings in summer.

ProblemsThrips, scale, anthracnose, rust, and leaf spots. Wilt and root rot, particularly in hot and humid climates.
