Achillea filipendulina

Achillea filipendulina

 

Common name: fern-leaf yarrow
Family: Asteraceae
Leaf: deeply-dissected, 1-2 pinnatifid, hairy, fern-like, aromatic (spicy) green leaves (each leaf up to 10" long, and divided to up to 15 pairs of linear-lanceolate toothed segments), from a basal clump.
Flowers: tiny, long-lasting, bright golden yellow flowers appear in a dense flattened plate-like compound corymbs that are up to 4" across, thought summer on erect stems rising above the basal foliage 3-4' tall.
Habit: herbaceous rhizomatous perennial; Form: clumping
Height: 3-4'; Spread: 2-3'
Culture: Best grown in lean, dry to medium, well-drained sandy loams in full sun. Does well in average garden soils and tolerates poor soils with good drainage. 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. Deadhead spent flower heads 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). Propagate by seed, cuttings or division. Hardy in USDA zones 3-9.
Uses: Specimen, group or mass. Borders. Cottage gardens. Containers.
Origin: Caucasus, Iran, Afghanistan, Central Asia
