Summer Pastels Group provides a variety of pastel flower shades, including pink, red, white, yellow, salmon, orange and mauve. Tiny flowers are densely packed in large, flat-topped, terminal flower clusters (corymbs) which are 2 to 3" across. Green leaves are deeply-cut, fern-like and aromatic when crushed. Tolerant of heat and humidity, but flower colors may fade in extended, hot summer weather. Drought tolerant once established. Long summer bloom period may be extended by prompt removal of faded flower heads.
Best grown in lean, dry to medium moisture, well-drained sandy loams in full sun. Does well in average garden soils and tolerates poor soils as long as drainage is good. Avoid heavy clays and moist, rich, fertile soils. Plants are best sited in locations protected from strong winds. Deadhead spent flower heads to lateral buds to promote additional bloom. Cut plants back to basal leaves after flowering to tidy the planting and to encourage new foliage growth and a possible additional fall bloom. Divide clumps as needed (every 3-4 years) to reinvigorate plantings.
