Subalpine Fleabane: A Hardy Native Wildflower for Cool Climate Gardens
If you’re looking for a charming native wildflower that can handle tough conditions while attracting pollinators, subalpine fleabane (Erigeron peregrinus peregrinus var. peregrinus) might just be your new garden favorite. This delightful perennial brings the beauty of alpine meadows right to your backyard with its classic daisy-like blooms and easygoing nature.
What Makes Subalpine Fleabane Special
Subalpine fleabane is a true native gem, naturally occurring across Alaska and extending into Oregon. As a herbaceous perennial forb, this plant lacks woody stems but makes up for it with its resilient root system and ability to return year after year. The name fleabane comes from an old belief that these plants could repel fleas – though we can’t vouch for that particular superpower!
You might also see this plant listed under its synonym, Erigeron unalaschkensis, in some older gardening references.
Where This Native Beauty Grows
This hardy wildflower calls the subalpine and alpine regions of western North America home, with populations thriving in Alaska and Oregon. It’s perfectly adapted to the challenging conditions of high-elevation environments, making it an excellent choice for gardeners in similar climates.
Garden Appeal and Design Uses
Subalpine fleabane produces lovely white to pale pink flowers with bright yellow centers, typically measuring 1-2 inches across. These classic daisy-like blooms create a cheerful display that looks right at home in:
- Rock gardens and alpine plant collections
- Native plant gardens showcasing regional flora
- Naturalized wildflower meadows

Perfect Growing Conditions
This mountain native thrives in USDA hardiness zones 3-7, making it ideal for gardeners in cooler climates. Subalpine fleabane prefers:
- Well-drained soil (essential for preventing root rot)

- Areas with good air circulation
Once established, this tough little plant becomes quite drought tolerant, though it appreciates consistent moisture during its growing season.
Planting and Care Tips
The beauty of subalpine fleabane lies in its low-maintenance nature. Here’s how to help it thrive:
- Plant in spring after the last frost date
- Ensure excellent drainage – this is non-negotiable for alpine plants
- Water regularly during the first growing season to establish roots
- Once established, reduce watering as the plant becomes drought tolerant
- Avoid rich, heavily fertilized soils which can make the plant leggy
- Deadhead spent flowers to encourage continued blooming
Wildlife and Pollinator Benefits
Subalpine fleabane is a pollinator magnet, attracting native bees, butterflies, and other beneficial insects with its nectar-rich flowers. By planting this native species, you’re supporting local ecosystems and providing food sources for wildlife that have co-evolved with these plants over thousands of years.
Is Subalpine Fleabane Right for Your Garden?

However, gardeners in hot, humid climates or those with heavy clay soils might find this alpine native challenging to grow successfully.
