The only family of interest to us here is the cabbage family.

Erysimum 'Bowles' Mauve'

Erysimum ‘Bowles’ Mauve’

This is an important family economically, containing a large number of our winter vegetables along with the oil seed crop rape. It also contains a number of very ornamental garden worthy Genera.

Did you know, there is a genus in the animal kingdom also called Crambe. Crambe crambe is the red encrusted sea sponge ! (see also the entry under Viola in Malpighiales)

Crambe cordifolia
Erysimum 'Sunburst'
