Have you ever thought of either ebay or trading them for your heart's desire? I made enough money on mine that it eased my broken heart on getting rid of the most of them. I did make a few trades with people I knew and those were for a few pretty rare philodendrons.
I considered E-bay but decided that I could not deal with all of the effort required with the packing and shipping. The only other thing that I can think of is to sell them at the Saturday Farmer's Market.
You have a lot of good suggestions here but the list of Cats. goes on, 'n on, 'n on. Depends on personal taste which you will develop in time. You might want so spend some time going thru the galleries of OB members there are truly some real beauties posted. Good luck.
Thank you everyone. The problem is that all of the are so beautiful. I have to control myself. I think I may definitely go the way of thumper and just specialize in something. The problem is finding the something that I want to specialize in. Sigh. Thanks everyone!!
Charlie, most of the plants are between three and four feet tall and I just don't want to deal with packing and shipping. It would probably cost as much as the plants are worth. Thanks for the suggestion though.
