Family:Brassicaceae

Wallflower is a compact, mound-forming herbaceous plant that can be either a perennial or biennial, known for its vibrant, long-lasting blooms. In southern regions, it is often cultivated as a cool-season annual. Typically, these plants have a short lifespan and are frequently regarded as biennials. The various hybrids are available in a wide range of colors and have been developed to extend their flowering period. These striking flowers appear in summer, showcasing clusters of pink, orange, yellow, or red.

For optimal growth, plant them in average to sandy soil with full sun exposure. Once established, they exhibit drought resistance and are also unappealing to deer. Wallflowers are ideal for use in rock gardens, at the front of borders, along pathways, or in container arrangements.
