Liatris, also known as blazing star or gayfeather, is a stunning perennial that blooms in late summer to fall. Its tall, spiky flowers attract pollinators like bees and butterflies, making it a favorite in many gardens. To ensure healthy growth and overwintering success, choosing the right companion plants is essential. These companions can provide protection, improve soil health, and enhance the overall garden ecosystem.
Why Companion Plants Matter for Liatris Overwintering
Overwintering is a critical phase for Liatris, especially in colder climates. Proper companion plants can help insulate the roots, reduce frost damage, and create a microclimate that benefits Liatris during harsh winters. Additionally, some companions can suppress weeds, retain soil moisture, and enrich the soil with nutrients, all of which support Liatris’s health and vigor.
Top Companion Plants for Liatris Overwinter
- Ornamental Grasses – Such as Little Bluestem or Switchgrass. These grasses provide a protective canopy and help insulate the Liatris crown during winter.
- Sedum – Low-growing sedums act as ground cover, shielding the roots from extreme cold and reducing soil erosion.

Additional Tips for Overwintering Liatris
Besides selecting the right companions, consider mulching around Liatris with straw, shredded bark, or compost to protect the roots from freezing temperatures. Cutting back the dead stems in late fall can also reduce disease and prepare the plant for new growth in spring. Ensure the soil is well-drained, as waterlogged conditions can harm overwintering Liatris.
Conclusion
Choosing the right companion plants is a simple yet effective strategy to support Liatris through the winter months. By planting ornamental grasses, sedum, ferns, and other hardy companions nearby, gardeners can create a resilient and beautiful garden space that thrives year after year. Proper mulching and care will further enhance overwintering success, ensuring Liatris continues to bloom vibrantly each season.
