General Culture:

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. Tolerates hot, humid summers and drought, and is considered to be one of the best yarrows for the St. Louis area. Plants are best sited in locations protected from strong winds. Although the tough stems of this hybrid are stiff, they do have a tendency to flop, particularly if grown in less than full sun or in overly rich soils. 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 when they become overcrowded (every 3-4 years).

Noteworthy Characteristics:

'Coronation Gold' is an upright, clump-forming hybrid yarrow which is noted for its deeply-dissected, fern-like, aromatic, silvery to gray-green foliage and its tiny, long-lasting, bright mustard-yellow flowers which appear in dense, flattened, plate-like, compound corymbs (to 4" across) throughout the summer on stiff, erect stems typically rising 2-3' tall. Foliage has a strong, somewhat spicy aroma which persists when used in dried arrangements. Generally considered to be a cross between A. filipendulina and A. clypeolata. Foliage resembles that of the A. filipendulina (fern-leaf yarrow) parent, but plants are more compact.
