With its upright form, drought tolerance, and low maintenance needs, ‘May Night’ is a reliable favorite for both formal and informal landscapes.
Seasonal Beauty & Growth
Spring:
Early in the season, grey-green foliage forms a compact clump, giving way to upright stems topped with intensely dark violet-blue flowers—one of the earliest salvias to bloom.
Summer:
As flowering peaks from late spring through midsummer, dense flower spikes rise above the foliage, attracting bees, butterflies, and hummingbirds. Regular deadheading extends the blooming season.
Autumn:
After flowering, the spent stems can be cut back to encourage a neat form and possible late flush. Foliage remains present and aromatic.
Winter:
Herbaceous perennial that dies back in colder regions but reliably returns each spring. In mild areas, some foliage may persist.
