Culture
Easily grown in average, dry to medium, well-drained soil in full sun. Prefers moist, gravelly or sandy soils with good drainage, but tolerates drought. Plants may repeat bloom throughout the summer and even into fall, but need regular moisture and deadheading to encourage this. Plants may become somewhat floppy and open up as the summer progresses, particularly in humid climates. If plants flop or otherwise depreciate in summer to the point where they look unsightly, consider cutting them back to the basal foliage. In any event, cut plants back after flowering has concluded.
Noteworthy Characteristics
Salvia nemerosa, commonly known as woodland sage, violet sage or salvia, is an erect, many-branched, woody-based, clump-forming perennial that typically grows 1.5-3' tall and to 2' wide. It is native to Europe and west-central Asia. Lavender to violet blue flowers (0.5” long) subtended by tiny reddish-purple bracts bloom in dense, terminal, upright, spike-like racemes rising well above the foliage from late spring to early summer, with sporadic reblooming through the rest of summer and into early fall. Flowers are attractive to bees and butterflies. Notched, wrinkled, ovate-lanceolate to oblong, medium green to gray-green leaves (to 4” long) are aromatic when bruised.
The genus name Salvia comes from the Latin word salveo meaning "to save or heal", in reference to the purported medically curative properties attributed to some plants in the genus.
Specific epithet means "growing in groves or woods", in reference to the native habitat of this species.
‘Schwellenburg’ typically grows 15-20” tall and features erect, rose-purple flower spikes that appear from late spring to early summer. Will repeat bloom with deadheading through summer and into fall. Lance-shaped, green leaves (to 3” long). Flowers are attractive to bees and butterflies. ‘Schwellenburg’ is sometimes sold by nurseries as a cultivar of Salvia x sylvestris or Salvia x superba.
