Dichanthelium aciculare, commonly known as Needleleaf Rosette Grass, is a perennial grass native to the southeastern United States, particularly thriving in pine flatwoods, coastal plains, and sandhills. It is adapted to sandy, acidic soils and is often found in open, sunny areas. This grass typically grows up to 2 feet tall and forms dense tufts or clumps. The narrow, needle-like leaves give it its common name, and while it may not be showy, it plays a crucial ecological role.

Needleleaf Rosette Grass is valued for habitat restoration projects and the management of native grasslands. It is resilient to poor soil conditions and drought, making it an excellent choice for erosion control and as a pioneer species in degraded landscapes. In cultivation, it requires full sun and well-drained, acidic soils to thrive. While it is not commonly used in ornamental gardening, it can be utilized in naturalistic plantings and as a ground cover in appropriate regions. Its ability to support a variety of wildlife, including pollinators and birds, adds to its ecological importance.CC BY-SA 4.0
