'Old Gold' A hybrid with grey-green leaves and broad, flat, golden yellow heads, 2-3 feet tall. Considered a rebloomer.
'Coronation Gold' A hybrid which is lower growing than A. filipendulina and generally requires less staking. Flowers are especially good for drying. A vigorous plant with good heat tolerance. 3 feet tall.
'Gold Plate' Tall growing plants with corymbs to 6 inches wide mustard-yellow flowers are useful as cut flowers.
'New Gold' A heavy flowering selection, 2 feet tall with golden yellow flowers. It is an excellent sturdy, long-lasting, cut flower.
'Parker's variety ' 3½ feet plant with yellow flowers in 4 inches diameter heads plant structure is more open than 'Gold Plate. '
'Anthea' Alan Bloom, Bressingham Gardens, Diss, England, developed this hybrid. It is 15-20 inches tall with long serrated silvery leaves. The flower color is slightly paler than 'Moonshine'. The secondary flower heads flower profusely as the terminal flowers decline. This cultivar, which is named after Alan's daughter, has potential as a cut flower.
'Credo' This is an upcoming cultivar developed by Ernst Pagel in Germany. It is a hybrid of A. filipendulina x A. miillfolium. It has large yellow flowers, a good texture and best of all, strong stems which do not need staking.
'Moonshine' This hybrid of A. clypeolata x A. taygetea has beautiful silver-gray, feathery foliage and bright yellow flowers. It is 2 feet tall and may be the best Achillea for the garden. It performs well in Northern gardens but high humidity and moisture in Southern zones often causes melting out. This excellent hybrid was developed by Alan Bloom in the 1950s.
Border, cut flowers and dried flowers. If the flowers are cut before pollen development, the dried heads will retain their color.
