Thymus serpyllum ‘Coccineus’

Red Creeping Thyme

Thymus serpyllum 'Coccineus', also known as Red Creeping Thyme, is a mat-forming herb that produces a dense carpet of vibrant magenta-red flowers in early to mid-summer. The tiny, fragrant blossoms create a striking contrast against the small, aromatic green leaves, making it a popular choice for ground cover, rock gardens, or between stepping stones. When in full bloom, its bright color draws attention and attracts pollinators like bees and butterflies.

Design tip

Use bold flowering drifts to define pathways, soften stone edges, or connect separate planting beds with repeating color. Surround the vibrant blooms with silver foliage and fine-textured grasses to create contrast while maintaining a balanced, cohesive landscape.
