I guess this is the best thread to post this. I never got round to repotting the 2022 seedlings, but all appear hearty in their original communal pots, and look to have had zero losses outside all winter. I promise I will move them to their own pots when the growth hardens in late May or early June! Here is a picture of the dissectums looking good! A couple more have germinated this spring too.
Seeds from 2021, but the one in the bottom right-hand corner germinated this spring : It's still very young yet, but if it survives and keeps the same colours, I'll call it 'Rich10'. OK with you @dicky5ash ?... ;-)
