Gigi that is a sweet thought but I'm not an expert lol. I've just grown aroids for a long time. I used to suffer from what some people in the plant game call 'Pokémon Syndrome'. You know, "gotta catch em all" meaning at one time or another I may have purchased and grown just about every common aroid that came up for sale. So I know what most of them look like on sight.
But with the explosion in the introduction of new species of plants like Anthuriums and Philodendrons that have been hitting the market over the past 5 years, I don't think anyone could keep up!
Not that many colocasias are introduced yearly. There are only a handful of people trying to breed new cultivars. Antiquorum Illustris is a very very old Colocasia
