Subalpine Fleabane: A Rare Mountain Gem for Your Native Garden
If you’re looking to add a touch of high-altitude charm to your garden, subalpine fleabane might just be the hidden treasure you’ve been searching for. This delicate perennial wildflower brings the rugged beauty of mountain meadows right to your backyard, though it comes with some important considerations for the conscientious gardener.
What Makes Subalpine Fleabane Special?
Subalpine fleabane (Erigeron peregrinus peregrinus var. thompsonii) is a native perennial forb that belongs to the diverse fleabane family. As a forb, it’s a non-woody flowering plant that dies back to the ground each winter and returns fresh each spring. Don’t let the common name fool you – this plant won’t actually help with your flea problem, but it will certainly attract beneficial pollinators to your garden!
This particular variety is native to the lower 48 states, specifically found growing wild in Washington state. It’s perfectly adapted to the Pacific Northwest’s unique climate and growing conditions.
A Word About Rarity
Before we dive into growing tips, there’s something important you should know: subalpine fleabane has a conservation status of S5T3, indicating it has some rarity concerns. This means if you’re interested in growing this beautiful native, you’ll want to source your plants or seeds responsibly from reputable native plant nurseries or seed suppliers who collect sustainably.
Why Consider Subalpine Fleabane for Your Garden?
Here are some compelling reasons to include this native beauty in your landscape:
- True native credentials: Supporting local ecosystems by growing plants that naturally belong in your region
- Low maintenance: Once established, native plants typically require less water and care than non-native alternatives
- Wildlife support: Native plants provide food and habitat for local wildlife species
- Unique character: Add something special and uncommon to your garden that most neighbors won’t have
Garden Design and Landscape Uses
Subalpine fleabane works beautifully in several garden settings:
- Native plant gardens: Perfect for Pacific Northwest native plantings

- Wildflower meadows: Adds authentic regional character to naturalized areas
- Alpine-style gardens: Brings high-elevation aesthetics to lower altitude landscapes
Growing Conditions and Care
While specific growing information for this exact variety can be limited due to its rarity, fleabanes generally prefer:
- Sun exposure: Full sun to partial shade
- Soil: Well-draining soils; avoid heavy clay or waterlogged conditions
- Water: Moderate moisture; drought tolerant once established
- Climate: Adapted to Pacific Northwest conditions
Planting and Care Tips
Success with subalpine fleabane starts with understanding its mountain origins:
- Plant in spring after the last frost date
- Ensure excellent drainage – these mountain natives don’t appreciate wet feet
- Start with small plants rather than direct seeding for better establishment
- Water regularly the first year, then reduce as the plant establishes
- Avoid heavy fertilization – natives typically prefer lean soils
The Bottom Line
Subalpine fleabane offers Pacific Northwest gardeners a chance to grow a truly special native plant that supports local ecosystems while adding unique character to the landscape. However, its rarity status means you’ll need to be a responsible gardener – source your plants ethically and consider this species as part of a broader commitment to native plant gardening.
If you can’t find this specific variety, don’t worry! There are other fleabane species and native alternatives that can provide similar garden benefits while being more readily available. The key is choosing plants that belong in your local ecosystem and supporting the web of life that makes your region special.
