Achilleais a genus of about 85 species of mostly herbaceous perennial from the Northern Hemisphere. Several hybrids are available.
'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 betweenA. filipendulinaandA. clypeolata. Foliage resembles that of theA. filipendulina(fern-leaf yarrow) parent, but plants are more compact.
As well as being easy to grow and adaptable, Yarrow is an excellent choice for gardeners of all levels. It can be used in various ways, such as in borders, rock gardens, and wild gardens. 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.
