Purple fountain grass, also known as Pennisetum setaceum ‘Rubrum’, is a stunning ornamental grass that has gained immense popularity among gardeners and landscapers. This particular grass variety is cherished for its rich purple foliage and graceful, fountain-like growth habit.
I first encountered purple fountain grass when I visited a botanical garden a few years ago. Its vibrant hues caught my eye from a distance, and as I approached, I was captivated by its striking beauty. The deep purple color of the foliage is truly mesmerizing, and it adds a dramatic flair to any landscape.
The scientific name of this grass, Pennisetum setaceum ‘Rubrum’, may sound complicated, but it essentially refers to a species of fountain grass with a purple color variation. The term “setaceum” denotes the fine, hair-like appearance of the grass blades, while ‘Rubrum’ indicates the vibrant purple color.
One of the reasons why purple fountain grass is so popular is its versatility in landscaping. It can be used in various ways to enhance the aesthetic appeal of a garden. Whether as a standalone plant, in mixed borders, or as a focal point, this grass is sure to grab attention and create a visually stunning display.
This grass is a warm-season perennial, which means it thrives in hot climates and is not frost-tolerant. It typically grows in clumps, with each clump producing long, arching blades that can reach a height of 2 to 4 feet. The graceful cascading growth habit resembles a flowing fountain, hence the name “fountain grass.”
During the summer months, purple fountain grass produces feathery, reddish-purple flower spikes that rise above the foliage, adding an additional element of beauty to its overall appearance. These fluffy blooms sway gently in the breeze, creating a sense of movement and life in the garden.
Purple fountain grass is relatively low-maintenance, making it a popular choice for both experienced gardeners and beginners. It requires well-drained soil and thrives in full sun, although it can tolerate partial shade. Regular watering is necessary, especially during the hot summer months, to keep the soil consistently moist.
In terms of care, pruning is an important aspect to ensure the health and appearance of the grass. In colder climates, it is advisable to cut back the foliage before the onset of winter to prevent frost damage. In warmer regions, periodic pruning is recommended to maintain the desired shape and prevent the grass from becoming too leggy.
When it comes to landscaping, purple fountain grass can be used in a variety of ways. It serves as an excellent border plant, creating a beautiful edge along pathways or garden beds. Its vibrant color also makes it an ideal choice for contrasting with other plants, such as yellow or white flowers, creating a stunning visual impact.
Furthermore, purple fountain grass can be incorporated into container gardens, where its cascading growth habit adds a touch of elegance. It pairs well with other ornamental plants, such as annuals or perennials, and can be used to create interesting focal points on patios, balconies, or decks.
Purple fountain grass, scientifically known as Pennisetum setaceum ‘Rubrum’, is a popular and visually striking ornamental grass that adds a touch of elegance and drama to any landscape. Its vibrant purple foliage, graceful growth habit, and low-maintenance nature make it a favorite among gardeners and landscapers alike. Whether used as a border plant, a focal point, or in container gardens, purple fountain grass is sure to bring beauty and charm to any outdoor space.
