Coccineus Creeping Thyme
Thymus serpyllum 'Coccineus'
herbCoccineus creeping thyme is a low-growing, aromatic groundcover with tiny, vibrant crimson-red flowers and small green foliage that becomes bronze-tinted in cool weather. This cultivar of wild thyme is prized for its ornamental appeal and culinary/medicinal properties, thriving in rock gardens, alpine troughs, and along pathways. It spreads slowly to moderately, creating a dense, evergreen mat that attracts pollinators.

Seedling/Establishment
2-3 weeksTiny rosette of fine-textured green leaves, minimal growth and root development
Keep soil lightly moist (not wet). Protect from heavy foot traffic. Provide bright light indoors or partial shade outdoors initially.
Vegetative Growth
4-8 weeksLow, spreading stems branching outward; dense mat of small leaves forms. Foliage color deepens; no flowers yet.
Allow soil to dry between waterings. Begin light foot traffic to encourage branching. Minimal fertilizer needed (too much nitrogen reduces flavor and vigor).
Budding & Early Flowering
2-3 weeksTiny crimson-red flower buds appear at stem tips; plant remains low and spreading
Increase air circulation to prevent fungal issues. Water at base only. Thin crowded stems if needed to improve flower display.
Peak Flowering
4-6 weeks (typically late spring through early summer)Abundant small crimson-red flowers cover foliage in dense clusters; plant appears as a red haze at ground level. Attracts bees and butterflies.
Deadhead lightly if desired to encourage more blooms, though flowers are short-lived naturally. Maintain dry conditions. No fertilizing needed.
Mature/Post-Flowering
4-5 months until dormancy or next seasonFlowers fade; plant retains dense, evergreen foliage that may bronze in cool weather. Seed heads remain ornamental.
Allow some seed heads to remain for wildlife and self-seeding. Light pruning (no more than 1/3 of growth) after flowering keeps plant tidy. Reduce watering further.

Harvest Tips
Harvest leaves and flowers anytime once plant is established (4-6 weeks after planting). Pinch or cut stems just above a leaf node in morning after dew dries. Best flavor just before flowering. Avoid harvesting more than 1/3 of plant at once to maintain vigor. Leaves dry quickly and can be stored in airtight containers for several months.
Fun Facts
- 🌱 The name 'Coccineus' comes from the Latin word for 'scarlet' or 'crimson,' referring to its distinctive vivid red flowers—among the showiest of all creeping thymes.
- 🌱 Creeping thyme has been cultivated since at least medieval times as both a culinary and medicinal herb; ancient Greeks and Romans used it in baths and as an incense for its aromatic and antimicrobial properties.
- 🌱 When walked on or brushed, creeping thyme releases fragrant volatile oils (including thymol) into the air, which is why it's perfect for planting between pavers on sunny pathways—the 'thyme walk' is a classic garden feature.
