About Silver hairgrass
Aira caryophyllea, commonly known as hvitsmyle or silver hairgrass, is a delicate annual grass forming small tufts. Its feathery, silvery inflorescences, appearing in spring and summer, give it an ethereal and light appearance. It is ideal for rock gardens, path edges, or as a filler plant in naturalistic garden styles, adding movement and texture.
Native range
Europe, North Africa, and Southwest Asia
Care tips
This grass prefers full sun exposure for optimal growth and abundant flowering. Watering should be moderate, allowing the substrate to dry slightly between waterings, as it tolerates drought well once established. It thrives in well-drained, preferably poor or sandy soils; avoid heavy, waterlogged soils. A common mistake is overwatering, which can lead to root rot, and excessive fertilization, which promotes foliage growth at the expense of flowering.
