Salvia 'May Night' Characteristics
'May Night' are hardy, easy to grow perennials with highly ornamental flower spikes. Deep, moist soils are preferable, but shallow rocky soils are tolerable.
'May Night' often survives well in some drought. Medium moisture soil is needed for repeat blooms. Removing spent flower heads can encourage additional bloom. The flower spikes may flop in hot weather or after flowering. After the blooming season, cut the flower stems back to the foliage for overall health and appearance. Propagation occurs by rapid spreading at the roots or plant division.
There are few serious disease or insect issues that threaten the health of 'May Night'. Powdery mildew, rust and leaf spot can occur. White fly and scale may make their home on these plants.
