Revered for its vibrant blossoms and aromatic allure, the Red Creeping Thyme transforms rock gardens into a red carpet event in the summer.

The Hens and Chicks plant, a popular succulent species, brings a touch of architectural drama to rock gardens.

With several varieties available, there’s a lavender plant suitable for almost any rock garden, whether it’s a sprawling landscape or a small nook in the backyard.

The icy blue hue of its fine, wiry foliage offers a visually cooling effect, providing a unique contrast to the warm tones of most rocks. Its compact, mounding growth habit ensures it won’t overrun other plants, making it an ideal complement to various rock garden species.
Blue Fescue Grass has the admirable trait of being extremely hardy.

The visual texture it brings to the landscape, particularly in winter when many plants are dormant, is invaluable. It serves as a beautiful, resilient addition to any rock garden design, tying together various elements into a cohesive whole.
Creeping Phlox (Phlox subulata)
