How big are the plug plants? Foxgloves are hardy but if they are seedling size then a cold frame or protected sheltered spot will be perfect.

i agree I'd wait until spring. If they conjestedroots you could always pot them on and keep in a sheltered spot.

I move foxgloves around my garden in autumn & they always grow & flower in the spring. If they are small plants they just flower later. Of course I'm meaning the ordinary pink ones tho' I have some nice white ones too,no fancy varieties .Don't know if they are more sensitive to cold or not. Feverfew.
