Where can I buy Phyteuma orbiculare plants or seeds in the USA? I am also looking for Calceolaria integrifolia plants. Thanks, Karl
Hi Karl, I don’t sell flowers, just write about them. But based on your questions did some research. I believe you can find Calceolaria integrifolia in U.S. I noticed it on a site Annie’s Annuals. I would suspect you can also find it at other nurseries near you as well. But Phyteuma orbiculare I could not find anything local to U.S. and I know there are restrictions in importing seeds or plants to U.S. I am not currently in U.S. but I am sure you can search online and see if you get better results than I did. Great to hear from you. Best, Dino
