Pruning purple fountain grass in winter is crucial for maintaining its health and appearance.
To properly prune purple fountain grass in late winter or early spring:
1. Avoid pruning before the grass starts regrowing
2. Do not prune in the fall before the plant goes dormant
3. Cut back any dead or brown growth to encourage new growth
4. Remove outer “stalks” or flowers to thin out the plant
5. Ensure to trim before active growth to prevent damage
Answering your first question on how to thin out the plant and what to do with the falling outer “stalks” (flowers) –the best time to prune fountain grass is late winter or early spring–but be sure to prune before the grass begins to re-grow. Also avoid pruning in the fall before the plant has had time to go dormant.
How do I protect my purple fountain grass in the winter?
To protect your purple fountain grass in the winter, ensure to provide adequate insulation. In regions with heavy frost, consider growing it as an annual rather than a perennial. Purple Fountain Grass (Pennisetum setaceum) is best suited for Sunset Zones 8-24 (USDA zones 9 and above). Adding a thick layer of mulch around the plant and covering it with a frost cloth can help protect it from harsh winter conditions. Be sure to remove any dead foliage to promote healthier growth in the next season.
Will purple fountain grass survive a freeze?
Purple fountain grass can survive a freeze. Although it is drought-tolerant, consistent watering is crucial during establishment. Provide new plants with 1-2 inches of water per week, allowing the soil to dry between waterings. This helps promote healthy growth and resilience to extreme temperatures. Additionally, consider mulching around the plants to provide extra insulation and protection during colder periods.
Will purple fountain grass come back each year?
Yes, purple fountain grass will come back each year if grown in warmer climates where it is a perennial grass. In cold climates, it should be planted in early spring and treated as an annual due to the plant’s inability to survive cold winters. This grass thrives year-round in warm regions, offering purple foliage and beautiful blooms through late summer and fall.
What temperature kills purple fountain grass?
Purple fountain grass is killed by freezing temperatures. Despite their vigor and durability, annual varieties must be replanted each spring because their roots cannot survive the winter. To protect purple fountain grass from cold temperatures:
1. Cover the plants with a thick layer of mulch before the first frost.
2. Bring potted plants indoors during winter.
3. Prune back the foliage in late fall to reduce cold damage.
How long does purple fountain grass last?
Purple fountain grass typically lasts for one to three years. To maximize its lifespan, ensure the plant is placed in a sunny location with well-draining soil. Mature plants can grow up to four feet tall and wide, so allocate ample space in the garden, spacing additional plants at least three to five feet apart. Regular pruning and dividing every few years can help rejuvenate the plant and prolong its lifespan.
What happens to purple fountain grass in winter?
Purple fountain grass is an annual, not a perennial as some stores may claim. It dies in winter. Consider other perennial grass options if desired. The dead grass can remain through winter as a decorative feature without needing removal in fall. Additionally, trimming it back in late winter can promote healthy regrowth in the spring.
Does purple fountain grass turn brown in winter?
Yes, purple fountain grass turns brown in winter because it is an annual plant, contrary to what some stores claim about it being a perennial. If you seek perennial grasses, there are alternative choices available. The dried grass can provide aesthetic value during the winter months and does not necessarily need to be cleared away in autumn.
In winter, consider these options for perennial grasses: miscanthus, switchgrass, or blue oat grass. Dead purple fountain grass can still add beauty in winter landscapes. While it may require more maintenance, some gardeners prefer to leave it as-is for added interest.
Will purple fountain grass survive the winter?
Yes, in regions with Sunset Zones 8-24 (equivalent to USDA zones 9 or higher), Purple Fountain Grass (Pennisetum setaceum) is a perennial plant. However, in regions that experience heavy frost or colder temperatures, it is typically cultivated as an annual.
1. In colder climates, purple fountain grass can be treated as an annual.
2. Winter protection such as mulching can help increase its chances of survival in borderline zones.
3. Consider bringing potted plants indoors during winter in colder regions to ensure their survival.
Is purple fountain grass drought-tolerant?

Does purple fountain grass attract bugs?
Purple fountain grass does attract bugs. To overwinter it successfully, cut it back significantly to eliminate old leaves and flowers, leaving only 2-3 inches (3-5 cm) high. Position the plant close to a sunny window in a warm room for best results. Additionally, consider the following tips: 1. Monitor for pests regularly. 2. Avoid overwatering to prevent fungal issues. 3. Provide adequate air circulation to deter pests.
Does purple fountain grass multiply?
Purple fountain grass can multiply by cutting back dead foliage in fall or spring. It is hardy to 20 degrees but may not survive very cold winters in North Texas, typically considered an annual grass. To ensure healthy growth and prevent overgrowth, follow these care tips:
