I got artichokes to bear in a single year. I started them indoors in jan (i’m in the deep south). put them in damp paper towels (the seeds) in ziploc baggies until i saw sprouts. planted those in teeny peat pots. put those peat pots in the fridge at night for 3 or 4 weeks (don’t remember) to simulate a ‘cold season’ for the seedlings. it was good to go from there.
they really need that ‘cold snap’ to think they’ve overwintered and need to bloom.
Thanks! I’ll have to try that.
