I received 6 bare root astrantia in early November. I live in zone 4. I have started them indoors. Since it is so late, should I leave them indoors until Spring? -

Yes, but they will need to be put into dormancy when indoors. You can do this by placing them in a cool, dark place and cutting back on watering. Bring them out again about a month before the last frost date and resume normal care.
