General Culture:
Easily grown in average, dry to medium moisture, well-drained soils in full sun. Tolerates drought. Prefers gravelly or sandy soils with good drainage. Plants may repeat bloom throughout the summer, but generally need regular moisture to encourage this. Remove spent flower spikes to help extend the bloom period. If plants flop or otherwise depreciate in summer to the point where they look unsightly, consider cutting them back to the basal foliage. In any event, cut plants back after flowering has concluded. May be grown from seed.
Noteworthy Characteristics:
‘Swan Lake’ is a clump-forming meadow clary seed strain that is noted for producing pure white flowers over a long summer bloom period. Wrinkled, ovate, light green basal leaves (to 6” long) form an attractive foliage mound. In late spring, upright flowering stems rise to 20-30” tall bearing terminal spikes of white flowers. If properly deadheaded, plants will continue to repeat bloom throughout the summer. Flowers are attractive to bees and butterflies.
Problems:
No serious insect or disease problems. Some susceptibility to powdery mildew, leaf spot and rust. White fly and scale are occasional insect pests.
Uses:
Perennial borders, cottage gardens, butterfly gardens or wild gardens. May be used as an edging plant.
