May Night Sage
Salvia x sylvestris 'Mainacht'
Plant Details:
Plant Type: Perennial
Plant Family: Lamiaceae
Plant Description: Upright clump-forming perennial with long-blooming deep-blue flowers starting in early summer. Mid to dark green foliage grows on upright stems which will flop over after blooming. These old stems can be cut back nearly to the ground to promote reblooming. Plant in well-drained soil and do not overwater.
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.
