I've seen it before and the only credence I give to it is that it is proof that leaf propagation is possible. It dismays me that blogger could have written an informative entry, but instead chose to leave out all the key data for replication. Even his most basic result, whether he got more than one bulb from the six leaves is doubtful, but unclear. He switches from singular to plural even in the same sentence!
When challenged, the blogger later admits that results are better with lilies that naturally produce bulbils, but still refuses to say if that is what he did in the blog test. You might have seen this addressed multiple times in the comments?
I've tried some leaf cuttings and stem cuttings of Lilium primulinum (an asiatic lily) and got roots, but no bulb.
