I potted up some seedlings of poncirus trifoliata (trifoliate orange). They were growing in a lady's yard. I'm excited about having a cold-hardy citrus here in Western NC. Has anyone tasted one? I looked it up on the internets and apparently it has quite a lot of bitter oil that will upset your stomach. Maybe I'll just make home-made citrisol (cleaning product) if the lemonade tastes terrible!
