Hello Can I please ask if anyone knows if you can make furtilizer from the foxglove plant? My elderly father makes his own furtilizer from comfrey and has now started to try and make some from foxglove. I'm worried as I know that foxglove (Digitalis) is poisonous. I have asked him to stop until I can get more Information I would be very greatful for any information you can let me have. Jacqui
