This hardy herb thrives in zones 4-10 and produces clusters of showy deep pink flowers from June to July that attract butterflies and pollinators.

What sets this thyme apart is its distinctive caraway fragrance that earned it the nickname "herb for flavoring barons of beef" from English cooks. The tiny, pointed leaves pack an aromatic punch that transforms potato salads, vegetables, and meat dishes with their unique scent. Its prostrate growth habit creates a dense, evergreen mat that tolerates drought, deer, and challenging urban conditions while providing months of pollinator-friendly blooms. This is one of the most versatile ground covers you can grow, equally at home cascading over rock walls or tucked into herb gardens.
The glossy, pointed leaves are harvested fresh to flavor potato salads, roasted vegetables, and meat dishes with their distinctive caraway fragrance. As a ground cover, it creates dense, evergreen mats perfect for rock gardens, slopes, and areas where traditional grass struggles. The plant also serves as an ornamental addition to herb gardens and naturalized areas, while the summer flowers provide nectar for butterflies and other pollinators.
