Creeping Caborn Wine & Roses Thyme is a ground hugging selection with dark, fragrant leaves that slowly spread. Small flowers bloom in summer and can nearly cover the foliage, creating a carpet of pink and red. Its creeping form will fill cracks in a rock garden or edge a mixed bed of other herbs or flowering plants. Thyme is a wonderful seasoning in most savory dishes. It is one of the fragrant herbs used in French cooking as well as many soups, stews and poultry dishes.
