Lawn & Garden

English wallflower, a relative of mustard, is an annual flower that is widely grown for cool season display. This sweetly fragrant flower is especially popular in England, where millions of these flowers are grown every year.

The English wallflower typically grows from 1 to 2.5 feet tall and has many branches. It produces showy terminal spikes in a range of colors, including creamy white, yellow, orange, tan, brown, and chestnut red. Some varieties are double.

English wallflowers do best in average, moist soil in sun or partial shade. They are ideal for areas with nighttime summer temperatures below 65 degrees Fahrenheit. In Zones 8, 9, and 10, they can be grown as perennials. In other areas, they are best grown as annuals for cool season display in spring or fall.

You can propagate English wallflowers by seed. When grown as annuals, sow seeds indoors 6 to 8 weeks before the last frost is expected. Germination takes 5 to 7 days at 55 to 65 degrees Fahrenheit. When transplanting to individual pots, pinch out the tip of the tap root to encourage a bushy root system. Sow seeds in July or August so that plants can winter over for the earliest spring flowering.

English wallflowers are versatile plants that can be planted in rock gardens, beds, and borders. They are also perfect for planting by sidewalks and doorsteps. Wallflowers will bloom all winter in a cool room in sunlight, and they also make good cut flowers.

Other related species of wallflowers include Erysimum hieraciifolium (Cheiranthus allioni), which is the closely related Siberian wallflower. There are also many separate, named varieties of English wallflowers, including Blood Red, Cloth of Gold, Eastern Queen (salmon-red), White Dame, and Fire King (orange-scarlet). Available mixtures include Bedding Mixed and Double Dwarf Mixed.
