Strictly, most common foxgloves are biennial which means they grow one year and flower the second. A few varieties such as digitalis ferruginea, are perennial where happy.

So moving the foxglove plant may not help as the original plant will die off, though it often self seeds or produces new plants from near the base.

The thing is, unless they were one of the newer perennial varieties, they won't flower next year, because they are biennials. You can collect seed again, however.

Sorry, Bertie, we crossed!

thank you both,
much appreciated

if I chance moving the foxglove when flower has subsided is it possible they will be ok to produce flowers every 2 years.
and I normally collect seeds from my plants, as a fall back if they don't come back. they r just too big where they are and they overshadow my ornamental cherry tree, what ever was I thinking putting them there in the first place but the huge bed where I now want them wasn't ready. oh dear!!!

Biennials die after they have produced seed. I find that foxgloves self-seed quite well, or you can collect the seed and use that , but the plants won't flower until the second year. If any self-seeded last year, of course, they will flower next year.

I have left Foxgloves in the spot where they flowered but the leaves die back slowly and they will not reflower next year. Best thing I did was to scatter the seed where you want it to grow next year. I collect the seedlings (slugs seem to eat them if you do not :( )
