“Siberian wallflower” with bright yellow flowers.

An excellent plant for spring planting in the landscape, adding early color. Known for its golden-yellow flowers, long bloom period, and attractiveness to pollinators.

Short-lived perennial or biennial, often grown as an annual in colder regions. Presumably a hybrid, probably between Erysimum asperum and Erysimum bicolor .

Prefers full sun, but tolerates light shade.
