Fox gloves over winter
I planted some fox glove seeds about a month ago in pots. They have grown to about 6" and looking good. It's now getting cold at night. I live in Essex UK. Do I need to keep them frost free by bringing them in. Or plant them out in a bed.

They will need to be brought in this winter. Usually, you will want to plant these in spring, so that they have time to develop their root structure the first year. If they do not get a long period before the first dormancy, then it will not flower its second year.
Since these will only live for two year, if you want them to stay in the area, you will have to make sure that the first one that you plant makes it to flowering. This will take the patience of waiting the first year, then waiting for it to come back the second year to show flowers and go to seed.
