David of Venezuela, the author of this last article, states in the article that "Most Adeniums are self sterile and will not set a seed pod if self pollinated". I defer to David, as he has much more knowledge of and experience with Adeniums than I. Guess I had just been lucky with my limited experience.
I since found it much easier to just order seed from Ko of Taiwan than worry with producing them myself. Plus the genetic diversity available is awsome.
