Description

Golden lemon thyme is a low, mat-forming subshrub growing 4–6 inches tall and spreading 12–18 inches wide. The tiny, rounded leaves are variegated with bright golden-yellow margins and green centers, releasing a strong lemon-citrus fragrance when crushed. In early summer, it produces clusters of tiny, pale lilac-pink flowers that attract bees.

Cultivation

Thrives in full sun with gritty, well-drained, alkaline soil. Drought tolerant once established. Hardy in zones 5–9. Shear lightly after flowering to maintain density. Avoid heavy mulch and wet winter conditions. Excellent for rock gardens, between stepping stones, and spilling over walls.

Culinary Uses

The lemon-scented leaves add bright citrus notes to fish, chicken, vegetables, teas, and herb butters. Use fresh or dried. The golden foliage makes an attractive edible garnish.

Garden Value

One of the best thymes for foliage color contrast. Deer and rabbit resistant. Tolerates light foot traffic. Combines well with purple-leaved plants, lavenders, and sedums.
