HOW TO GROW

Sowing: For best results, direct sow in the fall for germination in the spring. Since this seed needs light to germinate, sow it on the surface of the soil and compact it lightly. For spring planting, mix the seed with moist sand and store it in the refrigerator for 30 days before direct sowing on the surface of the soil. This seed can also be started indoors, sown on the surface of a flat; keep the soil lightly moist and at a temperature of 65-70 degrees until germination, which should occur within 10-15 days. Transplant the seedlings after the last spring frost.

Growing: Though it prefers well-drained soil, this plant can adapt to many soils including clay. Water the seedlings regularly until they become established; mature plants can tolerate some dryness, but appreciate occasional watering. Too much moisture or wet soil will cause disease. For the healthiest growth, keep the area weeded to reduce competition. This plant usually develops leaves in its first year and blooms in the second, and regular deadheading will allow the greatest number of blooms. Wallflower is often grown as a biennial, though classified as a perennial; it will also reseed itself, though the plant can be trimmed back after blooming to prevent this. If overwintering this plant, cover it with a layer of mulch for protection. This plant attracts butterflies, resists deer, and grows well in containers.

Harvesting: Wallflower makes an excellent cut flower, and has a pleasant fragrance. Cut long stems of flowers that have just opened, and remove leaves that will fall below the water level; place in water immediately.

Seed Saving: This plant will develop long, thin seed pods that turn from green to yellow to brown; mature seed will be a dark orange or rust color. Since the pods will split and release their seed when fully ripe, they must be harvested promptly to avoid loss. Remove the pods individually as they ripen to a light brown, and spread them out to dry. Alternatively, the entire plant can be pulled when most of the pods are ripe and hung upside down to dry. Separate the seed from the pods. Store the seed in a cool, dry place.

Botanists believe that the Siberian Wallflower, rather than coming from the European strain, originates from the Erysimum family of native American wallflowers. Presumably, this species acquired the name “Siberian” because of its excellent cold hardiness; it thrives in the damp, cool weather of coastal regions or higher altitudes. Its common name comes from the plant’s affinity for nooks and crannies in walls or cliffs. Records show that this plant once had many herbal and medical uses, as well as being used in perfume because of its fragrance. In the language of flowers, the wallflower also symbolizes disappointment in love.
