Purple fountain grass stands out with its graceful, purplish flower spikes and long, burgundy leaves—making it the ultimate flex for any garden enthusiast looking to add some drama to their landscape. This ornamental grass grows crazy fast and thrives when planted in spring with at least partial sun. While it can survive winter in Zones 9 and above, it also serves as a stunning annual in northern gardens. The plant's attractive autumn seed heads are especially lit in fall flower gardens.

🌱 Purple Fountain Grass Care

Here's the tea on keeping your purple fountain grass thriving:

• Planting Time: Spring is the move for establishment, but honestly, you can plant it whenever—it's that chill

• Support System: Use a stake for support and plant in an area protected from strong winds (don't let your grass get bullied!)

• Spacing: Give them plenty of room with at least 3 feet between plants—mature plants can reach about 5 feet tall and nearly as wide

• Planting Depth: Go for a hole both deep and wide enough to accommodate those roots

• Watering: Water thoroughly after planting and keep it hydrated twice a week

• Feeding: Fertilize regularly to keep the soil nutrients popping

Light Requirements 💡

Purple fountain grass will tolerate some light shade, but it's totally vibing with full sunlight. Look for an area in your garden where it can soak up that bright light for at least six to eight hours daily.

Soil Conditions 🌱

This grass isn't too picky about its soil—major plus! Loamy soil often gives the best results, but it can handle many types of mixtures as long as they're well-draining. No drama here!

Watering Schedule 💧

While purple fountain grass is considered drought-tolerant, you'll want to keep it consistently watered while it's getting established. New plants need water once or twice a week (about an inch total), allowing the soil to dry between waterings. Once established, you can basically let nature do its thing unless you're in a super dry area.

Temperature Tolerance 🌡️

This grass is cold weather hardy down to about 20°F. If your area stays above that, you can grow it as a perennial and cut it back each spring. New growth kicks in as temperatures rise—perfect timing!

Fertilizing Needs 🌿

Fountain grass grows well in poor soil, but fertilizer gives it that extra glow-up. During flowering season (typically summer), feed it monthly with general-purpose, slow-release food according to package directions.
