With Achillea ‘Firefly Diamond’, the flowerbed welcomes a plant whose flowers feature white tones. The foliage presents shades of green, to be highlighted among different textures. The usual flowering period is June-July. The clump reaches about 60 cm in height with an 80 cm spread; use these dimensions to place the plant in the middle of the flowerbed and for group plantings.
To plant Achillea ‘Firefly Diamond’, look for the following exposure: full sun and suitable soil (well-drained, rather light; avoid water pockets around the crown). After planting Achillea ‘Firefly Diamond’, water enough to thoroughly moisten the root ball. Once established, allow the surface to dry between waterings and prioritize drainage, especially during mild spells. Keep 80 cm as a general spacing between plants; this helps preserve their shape and allows access for care. The indicated hardiness zone is zone 3, to be considered according to your garden's conditions.
In an Achillea ‘Firefly Diamond’ planting, remove spent inflorescences when their appearance no longer suits you, while retaining healthy leaves. A too-rich location can soften the stems; reserve well-drained soil and measured fertilization for yarrows. For associations, consider upright sedums, catmints, and border salvias in varieties with similar needs. Keep its 60 cm height in mind to place lower plants on the right side and allow the flowers to be visible during June-July.
