Thymus vulgaris

Thymus vulgaris, commonly referred to as common thyme, is an herbaceous perennial that is primarily grown for culinary use. It is categorized as a subshrub due to its bushy form and semi-woody base. Growing up to 12 inches tall and 16 inches wide, common thyme has small purple to white flowers that appear in late spring to early summer. It is native to southern Europe and northern Africa where it prefers full sun and well-drained soils. 

Common thyme is a low-maintenance herb but has a tendency to spread. To reduce woody growth, it should be cut back in early spring. Even when pruned it may become woody after a number of years. Thyme also transplants fairly easily and should be done so in early spring. Thymus vulgaris makes a great addition to a pollinator garden as its flowers are attractive to bees, butterflies, and other pollinating insects. In the landscape, common thyme works well for herb gardens, rock gardens, and as an aromatic groundcover. 

The genus Thymus is derived from the Greek word thyo meaning to perfume. In Latin, vulgaris means common or usual.
