60d to harvest

Aromatic as a sunlit hillside, Thymus vulgaris ‘Argenteus’ unfurls with silvery, softly downy foliage that glows against deep green stems. The leaves carry a bright, thyme-forward flavor with a gentle, resinous lift—ideal for seasoning blends and herb-forward infusions. Grow it as a perennial that rewards close attention: snip sprigs for fresh fragrance, or let it dry for long-lasting culinary perfume.

Frequently Asked Questions

What pest or disease commonly affects Thymus vulgaris (Provence-type thyme), and how can I treat it?

The most common issue is fungal leaf spot/botrytis during cool, humid weather, often showing as dark spots or grayish growth on damp foliage. Remove affected sprigs, improve airflow, and avoid overhead watering; water at the soil line in the morning. If problems persist, use an appropriate fungicide labeled for edible herbs and follow label directions (especially keeping thyme harvest intervals in mind).

How often should I water Thymus vulgaris during active growth?

During the main growing phase, water only when the top 1–2 inches of soil feel dry; thyme prefers evenly moist only until established, then consistently on the dry side. Aim for deep, infrequent watering so excess water drains quickly, because Lamiaceae herbs like thyme are prone to root rot in soggy soil. If your soil stays wet or heavy, cut watering back further rather than trying to “hold” moisture with frequent sips.
