I am growing wallflowers for the first time this year. The plants are about to flower but annoyingly many of them have yellowed leaves. Any ideas what the problem could be?

Wallflowers are a brassica and as such thive in alkaline conditions. Did you add lime to the area they were planted in?
Having said that, when the plants are using most of there energies for flowering, the leaves have fulfilled there duties and will probably become a secondary concern to the plant.

Unless all the leaves are yellowing and the flowers are looking rather sick, this is not a problem. All brassicas lose some leaves as they mature; it could be down to lack of feed, too dry, too wet during the growing season of the plants. As Snadger says, you could give a foliar feed, but if the flowers are ok and smell as good as they should leave all alone - and enjoy!
