Foxgloves are a great addition to the garden, they are like Aquilegias and flower in the gap between the spring bulbs ending and the summer flowers beginning.  Foxgloves will grow in almost any situation, full sun to partial shade, tolerant of most soils, however avoid really wet or dry conditions.

Foxgloves are best planted in the autumn to over winter in the ground, like many other plants, once you have a foxglove, you will always have a foxglove, prolific seeders, new plants will sprout up around the base of the original plant. They can either be left or when large enough moved to a new location in the garden, I also pot some on to give to freinds and neighbours. If you wish to limit the seedlings growing, cut the flower spike as soon as the flowers have finished. 

Foxgloves are biennials so will usually die once the flowering has finished, although sometimes they will sprout again from the base, so look out for this before completly removing the plant.

Foxgloves can be highly toxic, so it is advisable to wear gloves when handling the plants, and, or wash your hands afterwards.
