Interesting that you should ask. I ordered them from a place on Etsy. I don't normally do that but being fairly new introduction, they are hard to find (impossible locally). I ordered them from ThePlantFinder store. I have to say I was pleasantly surprised. They were really well packaged (actually the best packaging I've seen) and arrived in great shape. I ordered them on a Sunday and they arrived on a Wednesday (Missouri to Cal.)
