To prevent that rampant reseeding with digitalis, I deadhead most of the stem after flowering, leaving just a few of the lower pods to set seeds. When the seeds are mature, I toss a pod or two where I want them next year. They usually sprout fast, start growing, and overwinter as small seedlings. Then they bloom the next summer.
I love the flowers (digitalis) in spring and early summer. But when the real heat arrives, the plants look like crap. They fry in the heat, the spider mites love them and make them look awful. I should probably stop growing them altogether, but I so love the early flowers.
