The Foxgloves, from potted plants, survive in some areas of my garden. I've tried the Millenium Delphiniums from seeds by winter sowing them, but they didn't survive once planted in the garden. Last year I found potted delphiniums from a local nursery, and they've been planted in the garden in a semi shaded bed, we'll see if they come back this spring.
Several years ago, I sprinkled a hummingbird and butterfly mix seed packet in a bed outside of my daylight basement, and the plants have been coming back for several years. Last year, I noticed a lupine plant growing from that seed mix.
I do love Foxgloves, lupines and delphiniums, and I'm going to keep trying to grow them to incorporate them in the peony beds, if they survive.
