Did You Know?
1. Despite its vibrant purple appearance, purple fountain grass (Pennisetum setaceum) is actually not a true grass at all – it belongs to the family of flowering plants known as Poaceae.
2. Purple fountain grass is native to the savannas and open woodlands of tropical Africa.
3. While purple fountain grass is typically considered an annual or tender perennial that is unable to survive harsh winter conditions, there are a few varieties that have been bred to be more cold-tolerant, such as ‘Fireworks’ and ‘Skyrocket’.
4. In areas with mild winters, purple fountain grass can sometimes survive if it is heavily mulched and provided with protection against frost. However, even if it does survive the winter, it often needs to be pruned back to rejuvenate and regain its full beauty in the following growing season.
5. In some regions where purple fountain grass is considered invasive, such as parts of Florida and California in the United States, it is prohibited to cultivate or sell this plant. It has the ability to crowd out native vegetation and alter the ecosystem, making it a threat to biodiversity.

Indoor Survival for Purple Fountain Grass
If you live in a region with cold winters that are not suitable for Purple Fountain Grass, there are steps you can take to help it survive. One option is to bring the grass indoors and treat it as a houseplant during the winter months.
To successfully overwinter Purple Fountain Grass indoors, follow these tips:
-
Choose a sunny location: Select a spot that receives plenty of sunlight, preferably a south-facing window. This will provide the grass with the necessary light for growth.
-
Monitor the temperature: Purple Fountain Grass prefers a warm environment. Aim to keep the temperature around 60 to 70 degrees Fahrenheit (15 to 21 degrees Celsius) for optimal growth. Avoid exposing the grass to cold drafts or extreme temperature fluctuations.
-
Water regularly: Remember to water the grass regularly to keep the soil moist. However, be careful not to overwater and cause waterlogged conditions, as this can lead to root rot.
Remember, indoors conditions differ from outdoor conditions, so closely monitor the grass and adjust care as needed.
Additionally, here are some bullet points summarizing the important steps:
- Choose a sunny location (south-facing window)
- Maintain a temperature between 60 to 70 degrees Fahrenheit (15 to 21 degrees Celsius)
- Water regularly, keeping the soil moist but not waterlogged

Digging Up and Storing Purple Fountain Grass
Another method for protecting Purple Fountain Grass during winter is to dig up the plant and store it in a cool, dry place. This process should be done before the first frost hits.
To protect the plant, follow these steps:
- Carefully dig around the base of the plant, being mindful not to damage the roots.
- Lift the grass out of the ground with as much soil as possible, ensuring that any excess moisture is removed.
- Trim the foliage back to a few inches above the crown. This will help reduce stress on the plant during storage.
Now, select a suitable location for storing the grass. Consider a place that is both cool and frost-free, such as a basement or garage. The ideal temperature range for storage is between 40 and 50 degrees Fahrenheit (4 and 10 degrees Celsius).
Place the grass in a container filled with dry mulch or peat moss. This will help insulate the roots and provide additional protection. Keep an eye on the grass, and if the soil becomes too dry, lightly water it.
Remember, by following these steps, you can ensure the winter survival of your Purple Fountain Grass.

Watering Dormant Purple Fountain Grass
During dormancy, it is important to provide Purple Fountain Grass with adequate hydration without overwatering. While the grass may not require as much water as during the growing season, it should not be left completely dry. Occasional watering will help prevent the grass from drying out completely.
To determine when to water dormant Purple Fountain Grass, check the soil moisture. Stick your finger into the soil up to your first knuckle. If it feels dry at that depth, it is time to water. Use a watering can with a fine spray nozzle to ensure an even distribution of water. Avoid soaking the grass and instead aim for a light and gentle watering.

Replanting Purple Fountain Grass in the Spring
When the threat of frost has passed in the spring, it is time to replant the Purple Fountain Grass in your garden. Choose a sunny location with well-draining soil and prepare the bed:
- Loosen the soil and incorporate organic matter to improve fertility.
Dig a hole slightly larger than the root ball of the grass. Place the grass in the hole, making sure the crown is level with or slightly above the soil surface. Fill in the hole with soil, gently firming it around the roots. Water thoroughly after planting to ensure the soil settles and eliminates any air pockets.
Collecting seeds from the grass and starting new plants is another propagation method for Purple Fountain Grass. Here’s how:
- Allow the grass to flower and produce seed heads.
- Once the seed heads have matured and turned brown, carefully collect them and store them in a cool, dry place.
- When the time is right, sow the seeds in a tray or pot filled with well-draining soil.
- Keep the soil consistently moist until germination occurs.
Propagation Tip: Purple Fountain Grass can also be propagated by dividing mature clumps in the spring.
Only in USDA zone 8 is Purple Fountain Grass hardy, while it is commonly grown as an annual in cooler areas. To protect it during winter, follow these steps:
- Bring it indoors
- Dig it up and store it
- Water it during dormancy
- Replant it in the spring
