Salvia x sylvestris 'Mainacht'

A true classic of the herbaceous border, Salvia x sylvestris 'Mainacht' — also known as 'May Night' — is an RHS Award of Garden Merit holder celebrated for its rich, deep indigo-violet flower spikes that emerge in late spring and early summer. Compact, reliable, and effortlessly elegant, it is a cornerstone plant for naturalistic and formal planting schemes alike.
