Noteworthy CharacteristicsWhite blooms and attractive, richly scented foliage.

CareRoot-hardy through Zone 6, possibly Zone 5, so stems die back to the ground each winter. Treat as a perennial in these zones. Performs best in full sun to partial shade. Tolerates heavy clay soils. Water well throughout the growing season and as winter approaches. Mulch heavily in late fall or early winter to protect roots.

PropagationStart seed indoors at 55° to 64°F in spring or summer.

ProblemsSusceptible to crown gall, gray mold, powdery mildew, collar rot, seedling blights, root rots, and stem galls, while aphids and scale insects are also common.
