Tridens strictus, commonly known as Longspike Tridens, is a perennial grass native to prairies, open woodlands, and savannas in the central and southeastern United States, with a disjunct population in western Pennsylvania. It typically reaches up to 6 feet in height and is characterized by its tall, slender spikes that bear purplish flowers during the late summer to fall season. The flowers are not particularly showy but add a subtle beauty to the grass’s overall appearance. Longspike Tridens is a facultative wetland species, indicating its adaptability to both wet and dry conditions, and it plays a vital role in its native ecosystem by providing cover and food for wildlife.

This grass is valued for its adaptability and is used in restoration projects, naturalized areas, and as a component in wildlife-friendly gardens. It is relatively low-maintenance, requiring minimal care once established. Longspike Tridens thrives in full sun to partial shade and can tolerate a range of soil types, from moist to well-drained. While it is not commonly affected by diseases or pests, it can become aggressive in some conditions, potentially crowding out other species.CC BY-SA 4.0
