Hi, was wondering if it is possible to cut back unruly leggy looking wallflowers and if so when is best time for this to be done

Wait until they've finished flowering, then cut back to the last two or three pairs of green leaves on each stem - they should then produce new shoots from low down. A bit of a feed at the same time won't go amiss.

These are really a short lived perennial usually treated as a biennial and ditched after one year' flowering and new plants raised each year from seed-they do end up rather straggly and woody if kept.

There is another pernniel  variey that you can take cuttings from that come in mauve or yellow-erysimum

Hello bryf,

I've got a very tall woody one that I'm fond of as it was one of the first plants that I grew from seed last year. It is flowering now so when it finishes I'm going to follow Alina W advice & see what happens.

I do agree with tdc, they do become very straggly. The upside is that you can easily collect seeds & grow some more for next year.

I've also got the perennial types  & will be trying to take some cuttings off these as from what I have been told they take really easily

I kept a blood red wallflower going for about 5 years by cutting it back as Alina suggests - but it eventually got too woody. If you've got the space to keep it, it's worth a go.

Thanks very much for all the replies, I will try out all of the advice, ie cutting back as Alina suggests, but as mine are Erysimum I will also take cuttings and collect the seeds, all advice much appreciated, cheers

Will the Erysimum stand cutting back and come back next year ?

Hiya lucky

Which Erysimum is it?  Bowles mauve will take a fairly drastic cut back.  Others can't take it.

Take cuttings now....they root quickly and will form good flowering plants next year
