Erysimum biennials

 

Biennial Wallflower

Most wallflower garden cultivars are derived from E. cheiri and have long been associated with cottage gardens. Producing early, fragrant blooms, it is often used in spring bedding schemes. (often placed in Cheiranthus), from southern Europe. Due to susceptability to fungal and bacterial disease, they are best grown as biennials and discarded after flowering.

Planting young plants

From Late Autumn TO Early Winter

Wallflowers grow well in full sun or light shade and should be planted in a well drained soil. They grow best in cool, moist climates but once the plant has become established in the garden, it is very durable and can withstand a certain amount of drought. In cold climates, be sure to provide ample mulch in the winter. Plant wallflowers in masses with summer flowering bulbs or include a few in containers planted with summer blooms. Set them out in the growing position in late autumn for spring blooming the following year.

 

Propogation by cuttings

From Late Spring TO Late Spring

Propagation of growing wallflowers can also be done by cuttings in spring. Semi hard wood cuttings are taken from the current years growth from late spring the bottom of the cuttings is hard and soft on the top. With a sharp knife take a cutting of about 14cms, remove lowest leaves, dip end into rooting hormone, and place round the edge of a pot filled with a suitable compost, water well, they must remain moist till rooted, place under glass but in semi shade.

 

Propagation by seed

From Early Summer TO Mid Summer

Wallflowers are easily started indoors from seeds. Keep the temperature within the growing medium at 55°-65°. Germination will take place within 7-10 days. Pot up wallflower plants using free-draining compost, and grow them on in frost free conditions until large enough to plant outside. When plants are well grown, acclimatise them to outdoor conditions over 7 to 10 days before planting outdoors on free draining soil in full sun.
