This superb
plant was named Perennial Plant of the Year in 1997. May Night sends up a vivid flush of
dark purple flower spikes in late spring, then takes a short break and resumes blooming in
mid-summer continuing to flower right up through most of autumn. It is a real flower
machine - just as long as you remember to remove faded flower stems on a regular
basis. One of the heaviest blooming perennials available.
Plant in full sun and provide a rich well drained soil. Fertilize in early
spring with a top dressing of compost and bone meal. Liquid feed twice in summer
with fish emulsion or seaweed extract. Plants are considered to be drought tolerant
but will bloom much better if you will provide them with water during hot dry spells.
Deadhead spent flowers to promote heavier flowering.
