Awesome answer, satisfying to know my train of thought was fairly in sync with a REAL professional!
I guess the mystery as well as diversity likely leads to my obsession with them
I've had great luck with sarian so far, I should point out that this is my first year with it, but it's out grown several of my alocasias, not the real rank ones like odora, portora, yucatan princess or even porteii, but it's growing well considering it was a plug in April...I bought and planted it with two 8" tall leaves in too much shade, then moved it in June to move sun as it was requesting...
All this still begs the question: where did sarian "come from"...
Same for frydek, I would think even if not hybrids people would still like credit for them...
It would have been relatively easy to apply for patents on both, tho it may not have been worth it...
I also wonder where I might find A. Micholitziana, non frydek, especially if they have colored pets.!
