Thymus caespititius, commonly known as Cretan Thyme, is an evergreen shrub native to rocky slopes and scrubland of the Iberian Peninsula and the Azores. This plant is a dwarf, aromatic, mat-forming groundcover shrub that typically grows to a height of 2-3 inches (5-8 cm) and spreads 6-12 inches (15-30 cm) wide. The narrow, spatula-shaped, smooth leaves are up to 6 mm (0.24 in) long, fringed with tiny hairs, and exude a pleasant fragrance when crushed. From late spring to summer, Cretan Thyme produces a profusion of rose, lilac, or white flowers in small, flattened heads that hug the mat of foliage, adding ornamental value to the garden.

Cretan Thyme is valued for its drought tolerance, aromatic foliage, and attractive flowers which are highly appealing to bees and butterflies. It is commonly used in rock gardens, as a ground cover, and in herb gardens for culinary purposes. Its low water requirements and adaptability to well-drained soils make it a suitable choice for xeriscaping. The cultivar Thymus caespititius ’Aureus’ is notable for its narrow, light gold leaves, adding a splash of color even when the plant is not in bloom. While it thrives in full sun, it can also tolerate light shade. It is hardy down to USDA Zone 7, but in colder climates, it should be protected from winter wetness to prevent root rot.CC BY-SA 4.0
