Native to southern Europe, wallflowers are the next best thing to pansies. These cool-season plants have a lovely fragrance and come in an abundance of colors. Wallflower is a short-lived perennial or biennial often grown as an annual with a long season of blooms. Plant wallflowers a few weeks before the last frost date for your region.

Wallflowers come in pale blues, greens, pinks, and creamy yellows, but you can also find them in warmer reds, oranges, hot pinks, and golden yellows. There are even varieties with color-changing blooms, which open bright yellow or orange and fade in shades of pink to a deep purple. When all colors show at the same time, it creates a striking display. Clusters of the four-petal flowers transition to narrow, pendant-shape seeds pods. The foliage is often bright green, narrow, and pointed.
Wallflower Care Must-Knows
Wallflowers grow best when planted in average, dry to medium, and well-drained soils. These plants like well-drained soils so much that it's how they got their common name: Wallflowers could often be found growing out of the mortar between rocks and bricks on the side of the wall. They suit rock gardens, border fronts, raised beds, and containers.
Place wallflowers in an area of the garden where they receive full sun in northern climates. In southern climates, they appreciate some afternoon shade. If you plan on growing them as a perennial, shear them back after initial bloom to promote dense bushy growth. If left too long, they become woody and leggy and will produce fewer and fewer flowers. Pruning also prevents plants from reseeding aggressively.
