With so many ornamental grasses out there, purple fountain grass – Pennisetum setaceum ‘Rubrum’ – is likely the most popular, and it is considered to be a tender perennial. It offers burgundy or purple foliage with fuzzy and soft blooms followed by purplish seed heads. It makes a bold statement within the garden, either on its own or with other plants. You’re going to find it very easy to grow purple fountain grass, and there’s little maintenance.
Therefore, this ornamental grass can’t survive through the cold weather, and it’s hardy in the warmer zones, such as 7, 8, and 9. Therefore, when planting purple fountain grass, consider this before you do it so that it returns each year. Often, cooler regions treat it like an annual.
It’s still possible to enjoy the plant every year when you put it in containers and bring it inside for the winter. You can also cut it back to about three inches and put it in a cool and sunny area of the house. Alternatively, it’s possible to put it in the basement.
Just make sure that you keep the purple fountain grass moist and water it once a month or so. When the freezing weather has gone away, and early spring comes around, set your beautiful purple fountain grass back outside.
Growing the Purple Grass
Purple fountain grass is a drought-tolerant plant and works well in warmer zones. It’s easy to maintain, and you’re going to like that you can plant it anytime. Spring is often the right choice for planting. The plant has to be put in a sunny spot, and well-draining soil is a must!
Mature plants can get about four feet tall and as wide as that. Give them enough room in the garden and keep other plants growing about 3 to 5 feet apart. You should dig a hole that’s deep and wide enough for the roots and give the purple fountain grass a thorough drink.
Caring for the Purple Fountain Grass
It’s easy to care for the purple fountain grass, and most gardeners like it for many reasons. Consider watering once a week or every other week when it’s in the garden. While it’s not required, it’s possible to give it an annual feeding of a balanced and slow-release fertilizer in the spring to stimulate new growth.
The right time to cut it back is in the fall before you bring it indoors. You may also find that if you leave it outside in warmer climates, it’s possible to bring it in during late winter. Growing is simple, and the care isn’t that hard, so this beautiful plant can bring happiness throughout the year.
