Shy Wallflower: A Humble Native with Big Garden Impact

Meet the shy wallflower (Erysimum inconspicuum), a native North American plant that lives up to its modest name while quietly delivering impressive benefits to your garden. Don’t let the inconspicuous part of its scientific name fool you—this unassuming little forb has plenty to offer gardeners looking for low-maintenance, wildlife-friendly plants.

What Makes Shy Wallflower Special?

This hardy biennial to perennial plant is a true North American native, naturally occurring from Alaska all the way down through Canada and across much of the United States. As a forb—essentially a non-woody flowering plant—shy wallflower forms attractive low rosettes and produces clusters of small, cheerful yellow flowers that bloom in spring and early summer.

Where Does Shy Wallflower Grow?

Shy wallflower has one of the most impressive natural ranges you’ll find in a native plant. It grows wild across an extensive territory including Alberta, British Columbia, Alaska, Manitoba, New Brunswick, Nova Scotia, Ontario, Quebec, Saskatchewan, Yukon, Northwest Territories, and dozens of U.S. states from Arizona and Colorado to Maine and Pennsylvania, and everywhere in between.
