Plant Profile: Erysimum x cheiri

Wallflower is a perennial subshrub commonly treated as a biennial or annual. It produces vibrant yellow to orange flowers from April to June, making it an excellent choice for cut arrangements. Various cultivars are available in different colors.

This plant thrives in well-drained soil and can adapt to small rocky areas, including walls. It prefers full sun to partial shade but benefits from afternoon shade during the hot summers in southern regions. To promote naturalization in your garden, prune the flower stems once the seeds have matured. Wallflowers are particularly suited for rock gardens and raised beds, but be cautious not to overwater or over-fertilize them.
