I had one plant last year and now have probably 15 foxgloves all over the year (front and back) so yes I would have thought it would have reseeded too :( But I had small plants last year from the seeds I saw in the fall - did you have a hard early winter? Maybe they were killed off

Yes, the lack of visible seedlings is indeed worrying. Normally, they would have made nice fat rosettes by last August, ready to go into winter.

OTOH, I too have grown the Dalmatian series (purple)....and will be resisting sending off for more seeds since the ones which did germinate were puny in the extreme, did not produce much viable seed and simply vanished in season 2 with no useful offspring. My main beef was the ridiculously small amount of seeds (which were pelleted for some reason) - around 25, of which less than half germinated and around 3 made it to transplanting. Course, it is likely to be down to my own negligence since I am having a similar struggle with D,grandiflora (although lutea, thapsus, parviflora and common old purpurea grow like weeds).

Many if not mot nearly all my Digitalis seedlings froze to death this past winter & I'm near the Chesapeake Bay, in a warmer zone, but that doesn't mean it wasn't a very severe winter! Only survivors were those from germination in very early spring, or from the year before.

'Dalmation' is an F1 hybrid from my understanding & that usually means the seeds produced, revert to a weaker plant, differing somewhat from the original crossing of two different parent plants. Horrible germination, was my experience... But the quality of T & M seeds seems to have gone downhill, over the years..

wouldnt it depend if you bought a first year seedling.. or a second year mature plant.. which would not come back???

i found.. that if i wanted seedlings and current flowers ... i had to buy a biennial.. two years in a row... to get the cycle going ... not two in one season ... in theory.. seedlings wont bloom the first year ...

rate of seedling emergence is highly variable.. as per micro climate ..... all you can do is wait and see if you find any ... unless you already weeded them out... lol.. been there.. done that ...
