About this plant
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.
Originating from Europe, 'Coccineus' is a variation of wild thyme that thrives in sunny locations and brings both visual beauty and a pleasant fragrance to the garden. Its hardiness and low-growing nature make it an excellent choice for adding texture and color to dry, well-drained areas. The plant's ability to release a thyme scent when walked upon adds an extra sensory element to its ornamental appeal, making it a favorite for pathways and borders.

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.
