Yes it is a Foxglove. I was given the name as Digitalis monstrosa. In 1983, we bought an acre of land which had been a nursery in the '20, '30 and '40's. Wherever I disturbed the ground, an amazing number of plants would grow. Hundreds of foxgloves would volunteer. One or two of the monstrosa kinds would appear each year. They would have a shorter stem of blossoms, with the giant open blossom at the top, opening first. Seed saved from them always reverted back to the normal digitalis purpurea - mostly pink, some white, some white with gold flecks inside.
I am a newbie. I hope I have answered this correctly.
