Maintenance:
Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
