About 3 or 4 years ago, I found the brightest red leafed rex begonia (I thought) in a hanging basket. The leaves were similar in size and shape to Angel Wing rex begonias, but very shiny and very bright red, like an anthurium petal. I thought the name had "dragon" in it, but all the "dragon wing" varieties I have seen have green leaves. I am at the mercy of your expertise to help me find it back. Maybe I am completely off track on the wrong species? Thank you all in advance for any help you can give me.
