Achillea millefolium 'Cassis'
Showy clusters of cherry-red flowers rise over a bushy mound of ferny green leaves.
Achillea 'Cassis' is an excellent choice for hot, sunny borders. It is easy to grow and vigorous, spreading by underground rhizomes.
Lift and divide every 2-3 years to control its spread.
Trim back hard after the first flush of blooms to maintain a compact habit.
Excellent for cutting and drying. A magnet for hover-bees and butterflies.
