I am jealous! I love foxgloves, and have been trying to get a colony going for years. I did succeed one time, they reseeded and returned the next year and it was wonderful. But that was 3 years ago, and I have had no luck since.

SO yeah I am jealous!!

Congrats on your seedlings! You must have good conditions for the seeds to germinate. Are they blooming this year or did they just sprout?

I have transplanted Foxgloves many times. They are tolerant of transplanting, even in the Spring. If your are small then they should transplant just fine. I would try to get a large rootball and disturb it as little as possible, and move them to a spot that's on the shady side. Then water well all summer.

My biggest concern about growing Foxglove is that it seems the crown can easily rot over the winter.

This is assorted D. purpurea in my front garden - Camelot Cream, Apricot Beauty, and some Excelsior hybrids. It was all started from seed last year. The ones in the foreground of this pic were transplanted there in April as fairly large clumps, to fill in some empty spots where the voles wiped out my perennials.

I've got about 6-8 blooming stalks and many non-blooming leaf rosettes around them. I took a close look today (it was raining before) and realized I have 2 colors: the typical pink spotted, and a pale yellow/ivory, much like the one in the center of your second photo, terrene. I don't know whether it crossed or (If I did get these in a swap), there was more than one plant in the pot.
I had a bloom stalk last year, but only pink, and I only recall there being one. I usually keep records of what I plant, but drop the ball on that concept frequently.
Though it is one of the sunnier parts of my yard, it does get some shade, and it tends to be moist there.

Jennypat, I too have tried many times! That's what make me think it was from a swap, as I don't see myself buying a foxglove when I have never gotten more than a year or two out of them. But I'm always willing to try someone's seedling: I seem to have much better luck with a garden grown seeding than a full grown nursery perennial. I'm guessing they are just more adaptable when small.
