Hollyhocks

year so often treated as biennials and new plants raised from seed or plants brought in. There are varieties that are more resistant than others to the disease Definitely don't try to lift them. They have deep roots and are not easy to transplant by Willie Wilson

Those lovely 'perenial' foxgloves being touted

've taken seeds from last year's foxgloves and they've grown to plants in pots which I'll put out in March but the original plants haven't kept going. I think I'm going to have to do this every year. British foxgloves, of course, are biennial, flowering by LearningSlowly

Honesty

does anyone know what it is??

if not always biennial, this looks like a perennial. Possibly one of the comphreys. Thanku for your reply nutcutlet, yes it is a perennial ( have got big fat roots!) but the leaves are slightly furry I thought comphrey's were smooth? They're quite rough by Jcblue

Wallflowers

. The ones you've got could be biennial. Easy to grow from seed which are produced after the flowering. Wall flowers or "Cheiranthus" are "perennials" although often treated as "biennials" they will grow almost anywhere and I have tubs of them around by cazzyb
