PlantFiles: Fern-Leaf Yarrow
Achillea filipendulina 'Coronation Gold'

This particular yarrow is sterile and will not self seed.

Achillea filipendulina 'Coronation Gold' has received AGM in 1993.

To deadhead, remove faded blooms to lateral buds. When all flowering is completed, cut down to basal foliage. Deadheading can significantly prolong bloom in young plants, but older plants may not benefit as much. Basal foliage can be left to remain for part of the winter and cutback in spring.

This yarrow produces sulfur yellow blooms. pokerboy.

I ordered this from High Country Gardens (GREAT) and was so pleasantly surprised. I have 5 of them that started out in 2inch pots and went in poor clay alkaline soil and were fantastic. The first season they were 3 feet tall. I prune them almost to about 8 inches in late winter and they keep coming back as a tough perrenial should.
They bloom prolificly and last all season, strong smell and remind me of some sages but the butterflys love them, they look great with Russian sage and Caryopteris Blue Mist Spirea. I think they are division propagated and mine LOVE gravel mulch.

A ready bloomer and needs little water, also does excellent as a cut flower or for drying. Also used in herbal medicine.

However, I have found that the flowers house alot little brown beetles and plant will need to be staked as it tends to flop over.

This plant has not done well in heavy, wet, clay soil for me. It is supposedly invasive. I have seen it planted with rudbeckia, which it contrasts with beautifully because of the different shapes of leaves and flowers.

'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 throughout the summer on stiff, erect stems typically rising 2-3'tall.Foliage has a strong,spicy aroma. Generally considered to be a cross between Achillea filipendulina and Achillea clypeolata.
