Salvia X sylvestris ‘May Night’
Most salvias give a lengthy performance in the garden, and cold-hardy 'May Night' delights with a late-season encore when regularly deadheaded. The plant's indigo-blue spikes of large flowers attract butterflies and hummingbirds and make a no-fuss addition to beds and borders. Mix with yellow flowers, purple sedums and lamb's ears.
