Common Wallflower Overview
Erysimum × cheiri is a spring-flowering evergreen perennial that produces fragrant bright orange-yellow flowers on short upright spikes popular with pollinating insects and humans alike. Also known as the Common Wallflower or Wall Gilliflower, this short-lived plant is often treated as a biennial - sown in summer to flower the following year - to provide masses of spring colour in wall side borders, patio containers or throughout flower borders in full sun with well-drained soil. Occasionally listed with the synonym name Cheiranthus × cheiri, many cultivars have been developed from this species with a wide range of colours. Semi-hardwood cuttings can be taken from your favourite coloured plants in spring or summer to continue your display the following spring. However, ready to plant bare-root plug plants are readily available in autumn. Soak the roots for half an hour before planting and space them 30cm (12") apart. Pinching out the growing tips of young plants - when they reach 12cm (5") in height - will encourage bushy growth and greater flower production. Once flowering has finished, prune these plants back to prevent them from getting too leggy. Water, apply a slow-release fertiliser and mulch to help the plant recover. This can encourage plants to produce a second flush of flowers in autumn.
Common problems with Common Wallflower
How to propagate Common Wallflower
Take semi-hardwood cuttings in spring and summer.
Between May and July sow seed directly into prepared seed beds with well-drained soil. Make drills 13mm (0.5") deep and space rows 30cm (12") apart. Water regularly during dry periods. Transplant young plants when they are large enough [autumn] to their final growing positions. Alternatively - sow into containers [seed trays, pots] and keep covered with a temperature between 13-15° (55-65°F). When large enough to handle, prick out seedlings into individual pots and grow on with cooler conditions, before planting out.
