This unassuming native perennial might just be the solution you’ve been searching for.

Think of it as the reliable friend in your garden who never lets you down, even when conditions get tough.
This hardy little plant produces charming daisy-like flowers and has adapted to thrive in some of the most challenging growing conditions nature can dish out. While it might not win any flashy flower contests, it more than makes up for it with its resilience and ecological value.

Alkali marsh aster is native to both Canada and the lower 48 states, with a range that spans an impressive portion of western North America. You’ll find it naturally growing in:
- Canadian provinces: Alberta, Manitoba, Saskatchewan, and Northwest Territories
