Achillea millefolium 'Proa White' - 9cm pot
Clumps of gray-green ferny foliage and upright stems of white flowers. An elegant and improved form with a good-sized flowerhead in a solid white, and highly aromatic foliage as a result of the higher essential oil content useful for medicinal purposes. Flowering height 60-90cm, spread 40-70cm. Achilleas prefer full sun and good drainage, plus an average soil - too rich or shady and they will be soft and will then need staking to keep them upright. 9cm pot.
