Houstonia procumbens, commonly known as Roundleaf Bluet, is a perennial herb that is native to the southeastern United States, particularly in pine flatwoods, savannas, and other moist, open, sandy habitats in Louisiana, Mississippi, Alabama, Georgia, Florida, and South Carolina. It typically forms low-growing mats reaching 2-6 inches in height, with distinctive round to oval leaves. The small, tubular, blue to lavender flowers, which are quite showy despite their size, bloom profusely from March to October, attracting pollinators such as bees and butterflies.

Roundleaf Bluet is valued for its long flowering season and its ability to thrive in sandy, acidic soils that are well-drained. It is often used in rock gardens, as a ground cover, or in native plant gardens where its low maintenance and drought tolerance are beneficial. While it prefers full sun, it can also tolerate partial shade. Gardeners should be aware that it may not perform well in heavy, clay soils or overly wet conditions. There are no widely recognized cultivars of this species, and it is generally free from serious pests and diseases. However, it can be sensitive to overwatering and root rot.CC BY-SA 4.0
