Description
Thymus × citriodorus ‘Aureus’ is a bright, beautifully scented thyme that earns its keep in every season. Its tiny golden leaves form a low, spreading mat that lights up gravel gardens, herb beds, borders, and pots—while releasing a clean lemon fragrance whenever you brush past.
In summer, it’s sprinkled with pale pink to lilac flowers that are irresistible to pollinators. It’s as useful as it is pretty: snip a few sprigs for roasting vegetables, chicken, fish, or to lift a simple butter sauce with a fresh citrus note. Tucked between paving, it softens hard edges and turns a walkway into something you can smell.
Compact, hardy, and drought-tolerant once established, ‘Aureus’ is a brilliant choice for sunny, free-draining spots where other plants can struggle.
Caragh Garden Notebook
Planting:
Plant in spring or early autumn for the quickest establishment. Space plants 25–30cm apart to knit together into a fragrant groundcover. Choose a sunny position—full sun keeps the foliage golden and the growth tight. Water in well, then allow the soil to dry slightly between waterings as it settles in.

Soil Preparation:
Thyme hates sitting wet. Aim for sharp drainage: lighten heavy soil with horticultural grit and compost, or plant on a slight mound/raised bed. In pots, use a gritty, free-draining compost mix and ensure drainage holes are clear.

Seasonal Care:
After flowering, lightly trim to keep plants compact and prevent them getting woody. Avoid cutting into old, bare wood. In very wet winters, container plants benefit from a sheltered spot (bright and airy) to reduce the risk of rot.

Pests & Problems:
Generally trouble-free. The main issue is winter wet—good drainage is the best prevention.
