Erysimum mutabile

Erysimum mutabile

Once known as Cheiranthus mutabilis, this is a shrubby perennial wallflower with narrow leaves, which hails from the Canary Islands and Madeira. The original species (ht 80 cm, pictured at left) had flowers which open pale yellow then age to mauve, blooming in spring. The cultivar 'Winter Joy' (ht 80 cm, pictured below) has pretty mauve flowers, which bloom from winter into spring. The plants enjoy a sunny, well-drained position, on the dry side, with a little lime added to the soil. It needs to be cut back after flowering to keep it compact, but it will only last a few years: propagate it from cuttings.

Erysimum Winter Joy

This plant combines well with other plants from this region and the Mediterranean which flower at the same time, such as Iris germanica, French lavender (Lavandula dentata) and Marguerite daisies.

Erysimum species are regarded as a good source of food for bees and hoverflies.

Flowers in July, August, September, October, November.
