Shenandoah switchgrass, also known as Panicum virgatum ‘Shenandoah’, is a popular ornamental grass that is loved for its vibrant red foliage and graceful plumes. This native hybrid grass can add texture and movement to any garden or landscape. In terms of size, Shenandoah switchgrass typically reaches a height of 36-48 inches, with the plumes adding an extra 12 inches to the overall height, making it around 48-60 inches tall.
One of the great things about Shenandoah switchgrass is its fast growth rate. It can quickly establish itself and fill out an area, making it ideal for mass plantings or as a focal point in the garden. In just a few growing seasons, you can see significant growth and a mature clump of switchgrass.
When it comes to width, Shenandoah switchgrass tends to spread out and form clumps that are about 18-24 inches wide. This means that when planting multiple switchgrass plants, you should space them accordingly to allow for their natural growth habit. Giving each plant enough room to spread out will ensure that they don’t become overcrowded and compete for resources.
It’s worth noting that the size of Shenandoah switchgrass can vary slightly depending on growing conditions, such as soil fertility, moisture levels, and sunlight exposure. In optimal conditions, it may even exceed the typical height and width measurements mentioned earlier. So, it’s always a good idea to consider the specific needs of your garden when planning the placement of switchgrass.
In my personal experience, I have found that Shenandoah switchgrass can be a versatile plant in the landscape. Its moderate height makes it suitable for both small and large gardens, as it can provide a nice backdrop or fill in gaps between taller plants. The red foliage adds a splash of color, especially in the fall when it intensifies to deep burgundy tones. And the airy plumes that appear in late summer and last into winter add an ethereal quality to the garden.
To summarize, Shenandoah switchgrass can reach a height of 36-48 inches, with plumes adding an extra 12 inches, making it around 48-60 inches tall. It forms clumps that are about 18-24 inches wide. However, keep in mind that these measurements can vary slightly depending on growing conditions. Overall, it is a fast-growing grass that can add texture, movement, and vibrant color to your garden or landscape.
