Digitalis Purpurea Not Flowering.

Question

I bought three MATURE digitalis rosettes from the garden center this spring. Two were planted in a partial shade situation, the third in full sun. Also, in late May, all my beds received a top dressing of two inches of compost and sheep manure. Everything in my garden is looking wonderful, except the three digitalis. They have lush foliage, measure more than a foot wide, but have no flower stalks. In an effort to get them to flower, I have further fertilized them with a high potash fertilizer. I am aware that foxgloves are biennials. That’s why I purchased mature plants at the garden center, and have also seeded digitalis seed in pots for next year’s beds. What have I done wrong? Why have my mature foxglove rosettes not flowered?

Answer 1

Has their garden been kept moist? Foxglove needs well drained, moist soil. Other than that, it sounds like you have done everything correctly. Did the nursery say it was the second year? I suspect it was the first year.

Another issue could be too much fertilizer. Here are their cultural needs:
