Cultivated forms of Erysimum are known all too well as the wallflowers of municipal bedding schemes, although they have become less popular in recent years. The colourful forms are derived from equally colourful (although with a narrower palette of colours) alpine species, which are generally finely scented.

Erysimum pulchellum has a prostrate woody framework clothed in narrow green leaves, above which stand short stems of 15 - 25cm of lemon yellow flowers, which will be a delight for weeks in early summer. It spreads slowly and seeds itself too. Good placed at a dry sunny border edge.
