Mountain Aster (Canadanthus): A Hardy Native Wildflower for Northern Gardens
If you’re looking to add authentic North American wildflowers to your garden, mountain aster might just be the unsung hero you’ve been searching for. This hardy perennial belongs to the genus Canadanthus and brings a touch of wild beauty to gardens across the northern United States and Canada.
What Exactly Is Mountain Aster?
Mountain aster is a perennial forb, which is simply a fancy way of saying it’s a non-woody flowering plant that comes back year after year. Unlike shrubs or trees, this plant puts its energy into producing flowers and seeds rather than building up woody stems, making it a perfect addition to wildflower gardens and naturalized areas.
Where Does Mountain Aster Call Home?
This native beauty has quite an impressive range across North America. You’ll find mountain aster growing naturally throughout Alaska and across Canada, including Alberta, British Columbia, Manitoba, New Brunswick, Ontario, Quebec, Saskatchewan, and the Yukon. In the United States, it thrives in northern states including Idaho, Michigan, Minnesota, Montana, Oregon, and Washington.
This wide distribution tells us something important: mountain aster is incredibly adaptable and hardy, making it a reliable choice for gardeners in these regions.
Why Consider Mountain Aster for Your Garden?
There are several compelling reasons to give mountain aster a spot in your landscape:
- Native plant benefits: As a true North American native, it supports local ecosystems and wildlife
- Low maintenance: Once established, native plants typically require less water, fertilizer, and pest control

Growing Mountain Aster Successfully

A Few Things to Keep in Mind
Mountain aster is one of those plants that hasn’t received as much horticultural attention as some of its showier cousins. This means you might need to do a bit of detective work to find seeds or plants, and specific growing information can be scarce. However, this also means you’ll be growing something truly special – a piece of authentic North American wilderness in your own backyard.
If you’re in mountain aster’s native range and want to support local wildlife while adding low-maintenance beauty to your garden, this hardy perennial deserves consideration. Just remember that working with lesser-known natives sometimes requires a bit of patience and experimentation to achieve the best results.
The Bottom Line
Mountain aster represents the best of what native gardening has to offer: authentic regional character, wildlife support, and low-maintenance beauty. While it might not be the flashiest plant at the garden center, it offers something more valuable – a genuine connection to the natural heritage of northern North America.
