Can anyone identify my mystery plant?
My Dad and I found some seeds he'd collected on a trip (possibly in Devon/Cornwall area) but unfortunately they were not labelled. They were sown in May/June this year and this photo was taken this morning. I have a couple I've put in the ground which are even bigger, approximately 2ft high but the photographed ones are sheltering in the greenhouse over winter as I suspect they may be a little frost tender.
Does anyone recognise this plant? And/or can anyone give me any advice on how to care for it?
