Phlox drummondii subsp. wilcoxiana, commonly known as Wilcox’s Phlox or Wild Drummond Phlox, is an annual herb native to Texas. It is typically found in sandy or rocky prairies, roadsides, and open woodlands, particularly in the Edwards Plateau and South Texas Plains. This species exhibits rapid growth, reaching heights of 0.5-1.5 feet (0.15-0.5 meters) and spreading 0.5-1 feet (0.2-0.3 meters). Wilcox’s Phlox boasts vibrant pink or white flowers that are quite showy, blooming profusely in the summer and attracting pollinators such as butterflies and hummingbirds.

The plant is valued for its ornamental flowers, which add a splash of color to garden beds and borders. It is often used in wildflower mixes, cottage gardens, and as a ground cover. Wilcox’s Phlox is relatively easy to maintain, requiring full sun exposure and medium amounts of water. It thrives in sandy or loamy soils with good drainage. While it is drought-tolerant once established, consistent moisture will promote more abundant flowering. Potential problems include susceptibility to powdery mildew and spider mites, especially in humid conditions. To prevent these issues, ensure proper air circulation around the plants and avoid overhead watering.CC BY-SA 4.0
