Eye-catching color: The deep burgundy or purple foliage of purple fountain grass is a real showstopper. It creates a striking contrast when planted among greenery or paired with vibrant flowers.

Now that we have established the allure of purple fountain grass let’s delve into the details of how to grow and care for it.
|Does purple fountain grass come back?
Yes, Purple Fountain Grass (Pennisetum setaceum ‘Rubrum’) is a perennial grass, and under the right conditions, it can come back every year.
It is hardy in USDA Hardiness Zones 9-11, where winters are mild. In these zones, Purple Fountain Grass may maintain its foliage through the winter, or it might go dormant and then regrow in the spring.
Planting Purple Fountain Grass
Like any other plant, purple fountain grass seed requires a suitable planting location and the right conditions to thrive. Here’s a step-by-step guide to successfully plant your purple fountain grass seeds:
Step 1: Choose the Right Spot
Purple fountain grass thrives in full sun, meaning it needs at least six hours of direct sunlight daily. Select a location in your garden or landscape that receives ample sunlight throughout the day.
Ensure that the soil is well-draining, as excessive moisture can cause root rot and other problems.
Step 2: Prepare the Soil
Before planting, prepare the soil by removing any weeds, rocks, or debris. Purple fountain grass prefers fertile soil with a slightly acidic to neutral pH range (6.0 to 7.0).
If your soil is heavy or clay-like, consider adding organic matter such as compost or well-rotted manure to improve its structure and drainage.
Step 3: Dig the Hole
Dig a hole slightly larger and deeper than the root ball of the grass. Gently loosen the roots of the plant, being careful not to damage them.
Step 4: Plant the Grass
Place the grass in the center of the hole, ensuring that the top of the root ball is level with the soil surface. Fill the hole with soil and gently tamp it down to eliminate air pockets. Water thoroughly to settle the soil around the roots.
Caring for Purple Fountain Grass
Now that your purple fountain grass is successfully planted, it’s time to learn how to care for it to ensure optimal growth and beauty. Let’s explore some essential aspects of caring for this vibrant ornamental grass.
While purple fountain grass is drought-tolerant once established, it benefits from regular watering during its initial growth period.
Newly planted grass should be watered deeply once or twice a week for the first month. Afterward, you can gradually reduce the frequency of watering to once every 1-2 weeks, especially during periods of prolonged drought.
Applying a layer of mulch around the base of your purple fountain grass can help conserve moisture, suppress weeds, and regulate soil temperature.
Use organic mulch such as wood chips or straw and maintain a thickness of about 2-3 inches. However, be sure not to pile the mulch against the grass stems as it can lead to rotting.
Feeding your purple fountain grass with a balanced slow-release fertilizer in spring can promote healthy growth and vibrant foliage.
Follow the manufacturer’s instructions regarding the dosage and frequency of application. However, avoid over-fertilizing, as excessive nitrogen may result in lush foliage but fewer flowers.
Purple fountain grass benefits from an annual pruning in early spring before new growth emerges. Cut the grass back to a few inches above the ground, removing any dead or damaged foliage. This process helps rejuvenate the plant, improves its appearance, and encourages fresh growth.
Managing Pests and Diseases
Purple fountain grass is generally resistant to pests and diseases. However, occasional problems such as aphids, slugs, or fungal leaf spot can occur.
Monitor your grass regularly and take appropriate action if you notice any signs of infestation or disease. Consider using organic insecticides or fungicides as a first line of defense, and always follow the instructions provided.
In regions with mild winters, purple fountain grass may remain evergreen. However, if you live in an area with freezing temperatures, you have two options to protect your grass during winter:
Leave it as is: Some gardeners choose to leave the grass standing to provide winter interest and protection for the crown. However, be aware that extreme cold can still damage the foliage.
Cut it back: Alternatively, you can cut the grass back to a few inches above the ground after it goes dormant in late fall. Mulch around the base to insulate the crown and protect it from freezing temperatures. Remove the mulch in early spring before new growth emerges.
|is purple fountain grass invasive?
It’s worth noting that purple fountain grass can be invasive in some areas, especially in hot climates. Check with local officials or gardening experts to make sure it’s suitable for your specific location.
