Carter, can you take a couple of pictures of that large fiddle you just bought, showing the three trunks? Are the trunks from three different plants or are they from one plant? How large is the pot you have it/them in? I would also love to see pictures of the variegated ficus. I have never seen one.
Perhaps you are right about the regional availability. I just don't know. All I know is the feedback I have gotten from people all over the US about not being able to find fiddle leaf ficus trees for sale. Growing (and selling) the fiddle is simply a novelty plant for me, since orchids, staghorn ferns, and bromeliads are my main interests. If people did not ask for it, I would not bother air-layering the mother plant.
