Bought some of the usual wallflowers in bunches, and now in their 3rd

You will need non-flowering shoots for preference, but you could always
nip the flowers off. I take wallflower cuttings any time the weather is
agreeable (so not mid-winter) and they usually take. In fact, I shall
be taking some cuttings very soon.

Thanks. How soon do you ditch the old ones? I rather like them waist
high and a bit scruffy!


I grow mostly the perennial ones (Erysimum), but I was only able to keep
bedding wallflowers for an extra year. They were very straggly and
scruffy by then. If you appreciate them in straggly mode carry on, but
don't forget they're a Brassica relative and can encourage Club Root, so
be careful where you plant them.
