I do most of my shopping online and have not had any problems at all. I do not buy from the big box stores because of the diseases they ignore and spread through their own lack of knowledge, to put it nicely. I do not buy from eBay because the buyer protection expires in 90 days and that is not enough time for a plant to bloom usually never mind a seed.
Thanks for the information on the Lungwort. I have seen some pretty ones and was wondering if they are at all invasive?
