Salvia × sylvestris 'May Night'

A superb perennial sage

Growing to 3' tall, violet sage has an upright habit and lovely grayish-green leaves. Numerous spikes of intensely violet-blue flowers emerge from red-violet bracts on this very popular hybrid sage. With its showy, long-lasting flower spikes, it adds pretty color and vertical form to the garden bed. Some references list cultivars under Salvia x superba.
