Plumbago Hardiness: Cape Leadwort vs. Hardy Leadwort

Two plants are sold as "leadwort." Plumbago auriculata (Cape leadwort) is a half-hardy perennial that usually dies in Georgia winters. Ceratostigma plumbaginoides is a fully hardy groundcover. Cape leadwort blooms all summer; hardy leadwort blooms only in fall. Cut dead Cape leadwort stems to 4 inches, mulch lightly, and hope for regrowth.
