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. Plants tolerate hot and humid summers with some drought. Plants are best sited in locations protected from strong winds. ‘Gold Coin Dwarf’ has short stems that are less apt to flop in the hot and humid summers of the St. Louis area. 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 possible additional fall bloom. Divide clumps when they become overcrowded (every 3-4 years).
Noteworthy Characteristics:
‘Gold Coin Dwarf’ is an upright, clump-forming yarrow that is noted for its bright gold flowers, ferny aromatic foliage and dwarf size. Many nurseries are advertising this cultivar as a dwarf version of A. filipendula ‘Parker’s Variety’ (see H250 herein). Flowers appear in dense, flattened clusters (compound corymbs to 4” wide) over a long summer bloom on dwarf stems rising to only 15” tall. Deeply-dissected, fern-like, green leaves are aromatic.
