Panicum virgatum Rubrum (Red Switchgrass) is a striking ornamental grass with upright, slender stems that take on a rich red hue in the late summer and autumn. This variety of switchgrass is known for its unique colouration, which deepens as the season progresses, creating a dramatic display in the garden. The feathery flower panicles bloom in late summer, adding a delicate, airy texture to the plant’s overall form.
With its ability to thrive in a variety of conditions, Panicum virgatum Rubrum is an ideal choice for low-maintenance, drought-tolerant gardens. It works wonderfully in borders, meadow-style plantings, and naturalized areas, providing seasonal interest with its beautiful colour changes and graceful appearance. The plant’s striking red foliage in autumn makes it a perfect addition for year-round garden appeal.
