36" tall x 24" wide. This always-dependable performer is an essential long-blooming perennial for any xeriscape. 'Coronation Gold' is taller than Achillea 'Moonshine', has greener foliage and a larger, darker-yellow flower cluster. This is a sterile selection and will not make a nuisance of itself and crowd out its neighbors like tall, yellow seed-grown varieties. A fine companion plant for other larger plants like Blue Mist Spirea and Russian Sage. Superb as a dried, everlasting flower. Salt Tolerant. (cutting propagated)
