flowering ...what have i done wrong???
If this is the first year, then this will be the issue. They are biennial, or short lived perennial. They spend the first year growing leaves and roots, and the second year as a reproductive stage.

The large foxgloves have shed seeds which have grown into small plants. Can I move them now? I don't have a photo.
Success with transplanting depends on the size of the plant and weather. I would not transplant anything less than 4 inches in size. You can move smaller plants but they will need very close monitoring since their roots are immature. With weather, cool and cloudy weather are ideal - less stressful for the plant. The August sun is still strong when shining directly on a plant. Rig up shade for new transplants for 3-5 days. Anything that shades the plant from afternoon sun is fine - an umbrella, old bedsheet, box or paper leaf bag over a shovel or pole. When the plant has recovered from being moved, try removing the shade. If the plant wilts in the sun, it is not ready to be in full sun. There is plenty of time for transplants to settle before winter if moved in Sept to early Oct. The 7-10 day weather forecast should guide your timing.
I bought a foxglove at the garden centre - it has 2 small stems win buds just starting to show - should I remove one so that the other can grow, or can I leave both and have 2 flower stems? Thank you
There is no need to remove the second flowering head. It will be quite interesting to see two flowering spires!

White colour has been left alone; it's just the pink flowers eaten away leaving stem and bud cap.
Slugs will eat the flowers at night then hide during the day. You can trap them by placing half an orange or grapefruit rind face down near the plants. In the morning collect and dispose of the slugs. Slug pellets also can be purchased.

I am studing foxglove. I am writing an article about it and wanted to know how long since someone has died of Foxglove.
The foxglove is over 6ft tall
This beautiful mutation is called a "sport." Here's an article that explains the phenomenon:

I have a couple perennial foxgloves which are also sterile. What is the best way to propagate these please?
If they are sterile, then there will be no way to propagate them. Since Foxglove only live for 2, and sometimes 3 years they complete their life cycle fairly quickly.
The first year is vegetative, and the second is spent flowering and producing seed. If there is no seed, then you will need to source some new seeds for the next season.
