Do these wallflowers need pruning?

    Wallflowers are usually grown as biennials i.e. Seed planted May/June plants grown on and put in final position in Autumn and they flower about late spring inthe following year. They will continue to grow after flowering but are usually past their best. I don't think they'd respond to pruning. They often self seed so no need to start from scratch if you like them where they are.

    I've cut them back once they've finished flowering, cutting just above a rosette of leaves - they stay compact and flower the next year, if you do that.  I reckon they're short-lived perennials really.

    Ok thank you :-) they’ve been here a few years now so, maybe I’ll cut them back when they finish this year :-)
