My astrantias still have flowers on but are past their best and foliage is looking a bit sad. If I cut them back now will they re-grow this season, or is it best to leave them until the autumn and cut back then?
If you cut them back now they will regrow some leaves but no flowers. If you want seeds I think you will have to leave at least a few seed heads on for a bit longer to ripen.

Thanks for that, I'll leave them then.
