Mike, I think your on to something about planting rooting and selling cuttings. Just got back from my local Walmart, they had about a hundred adeniums (all in plastic cups) getting $12.00 each. I checked every one of them, not only were they cuttings, but everyone was the common pink! I'm curious to go back in a few days and see if they sold any. Also every one of them were in bloom so I think they will be able to sell them just on the strength of the bloom.
