Mary, if they are already forming a spike then they'll bloom this year. There are some foxglove that will bloom their first year, I think they are called dalmation, and there are some true perennial digitalis that come back every year. I have one which right now I can't remember the name...it's small and pale yellow and is more of a soft clump rather than a tall spire. It's short lived but it has come back for three years now. Well, I don't know if it's going to come back this year, it's still early.
Digitalis grandiflora is also a true perennial, and will also self sow. Digitalis purpurea is a biennial.
Does the tag tell you the variety?
