It turns out they are pretty common around here and in many other places.
I had to do some research to see what this wondrous fruit was all about.
Here I was in Western North Carolina, and I was looking at an orange tree. The first time I saw a Flying Dragon, or Hardy Orange, I was in awe. The Flying Dragon Citrus tree, also known as Hardy Orange and scientifically as Poncirus Trifoliata is a cold-hardy deciduous citrus shrub.
