Thymus pseudolanuginosus 'Woolly Thyme', commonly known as Woolly Thyme, is a low-growing, mat-forming perennial herb prized for its soft, fuzzy silver-green foliage that gives it a velvety, “woolly” appearance. This thyme is mostly grown for its ornamental and groundcover qualities rather than culinary use. It's perfect for rock gardens, between stepping stones, crevices, and dry borders, where it adds fine texture and a soft, moss-like look.
Woolly Thyme is drought-tolerant, thrives in full sun, and needs well-drained soil. In summer, it may produce tiny pink to lavender flowers that attract bees and butterflies, adding a touch of color to its dense foliage.
