Summary

Clinopodium arkansanum, commonly known as Limestone Calamint, is an evergreen perennial herb native to limestone glades and rocky prairies, primarily in the Ozark region of Arkansas and Missouri. It typically grows to a height and width of 0.5-1 feet (0.2-0.3 meters), forming a low, mounding clump. The plant is characterized by its aromatic foliage and small, tubular flowers that are purple and white, blooming in the summer and attracting pollinators such as bees and butterflies.

Limestone Calamint is valued for its fragrant leaves, which can be used to make herbal teas, and its flowers, which add a delicate charm to garden settings. It is suitable for rock gardens, border fronts, and as a ground cover. This plant prefers calcareous soils and is drought-tolerant once established, making it a low-maintenance choice for gardeners. It thrives in full sun to part shade and requires well-drained soil. While generally disease-resistant, it can be susceptible to root rot in poorly drained conditions.CC BY-SA 4.0
