Hi Rosemummy, To me ripe is when they're loose on the seedhead. I scoop them up, on a dry day. I have some pots that are about 4'' deep and 6'' across, I like those for seeds then I can spread them out. Scatter the seeds,throw a handful of grit on top and leave them outside in a shady spot til summer's over. Then they all sit outside the GH til about February/March when I sometimes put them on the shelf in the unheated GH. This is more for my benefit than theirs, it's easier to watch for germination. If they're still outside when they germinate I bring them in so they grow quicker.
Astrantia germinates in the garden soil, around the parent plant, without any assistance.
