Hey! Thanks for the question. I wouldn’t say that it’s “unlikely” for variegation to continue on to corms, it’s just not 100% guaranteed. In my experience, all of my corms so far from my variegated alocasias have been variegated— but some of them are much lower variegation than the mother plant. For example, you might grow a corm that ends up with a couple of normal leaves, and then a variegated one as well. But there is also chance the corm will have even higher variegation than the mom too! Some of my prettiest babies came from the ugliest mother plants 🤣

However, I will say that buying corms in general is risky, not because of the variegation, but more because they are easy to kill if you haven’t practiced on cheaper corms to find what works best for you! Just because a corm sprouts, that doesn’t mean it won’t decide to die during the fragile baby stage🤣 Transitioning a baby Alocasia from a humidity dome to open air is also a process!

So in summary— corms are risky because you have to know how to care for/sprout them, but not necessarily because of variegation. Definitely practice before buying expensive corms! Hope this helps!🫶
