Prairie Blue Grass

Posted on by My Garden Channel

Prairie Blue Grass (also known as Panicum virgatum ‘Prairie Sky’) is a cultivar of switchgrass, a warm-season, ornamental grass native to North America. This grass is valued for its upright form, blue-gray foliage, and resilience in various growing conditions. It’s often used for landscaping, erosion control, or in prairie-style gardens.

Care Guide for Prairie Blue Grass:

1. Light Requirements:

  • Prairie Blue Grass thrives in full sun to partial shade.
  • It prefers at least 6 hours of direct sunlight each day for optimal growth.

2. Watering:

  • This grass is relatively drought-tolerant once established.
  • Water regularly during the first growing season to help establish a strong root system.
  • Once established, water only during dry spells, as it can withstand periods of dryness.
  • Overwatering can lead to root rot, so be sure the soil drains well.

3. Soil:

  • Prefers well-drained soil and can tolerate a range of soil types, including sandy or loamy soils.
  • It can handle slightly acidic to neutral pH (6.0 to 7.5).
  • Switchgrass is tolerant of poor soils, which makes it a good choice for low-maintenance gardens.

4. Temperature & Hardiness:

  • Prairie Blue Grass is hardy in USDA zones 4 to 9, which means it can survive cold winters in a variety of climates.
  • This grass thrives in warm temperatures but will also tolerate some cooler conditions.

5. Fertilizing:

  • Generally, prairie blue grass doesn’t require much fertilizing. However, if your soil is poor, you can apply a light layer of compost or an all-purpose fertilizer in early spring.
  • Avoid excessive fertilization, as this can result in weak, floppy growth.

6. Pruning & Maintenance:

  • Cut back the grass to the ground in late winter or early spring, before new growth begins.
  • This helps to remove dead or damaged foliage and makes way for fresh, vibrant growth in spring.
  • The plant’s seed heads can be left for winter interest or for birds to feed on.

7. Growth Habit:

  • Prairie Blue Grass grows 2 to 4 feet tall and spreads around 18 to 24 inches.
  • It has a clump-forming habit with blue-green leaves that turn more golden or reddish in the fall.
  • The seed heads are airy and soft, adding visual interest in late summer and fall.

8. Pests & Diseases:

  • Prairie Blue Grass is relatively pest and disease resistant.
  • Occasionally, you may see aphids, scale insects, or leafhoppers, but they generally don’t cause significant damage.
  • It is also resistant to most diseases, including powdery mildew.

9. Companion Plants:

  • Prairie Blue Grass works well with other native grasses, such as Little Bluestem (Schizachyrium scoparium), or wildflowers like Purple Coneflower (Echinacea purpurea), and Black-eyed Susan (Rudbeckia hirta).
  • It pairs nicely with other drought-tolerant plants, creating a natural, prairie-like landscape.

Special Considerations:

  • Deer-resistant: It is not typically a favorite food for deer, making it a good option for gardens in deer-prone areas.
  • Attracts wildlife: The seed heads provide food for birds in fall and winter.
