Re: Banana ID
It's always hard to tell what variety a banana plant is when it's young, but I agree with you that this certainly looks like a FHIA variety of some kind. I'm almost positive it's not a Goldfinger (FHIA-01) because there's way too much purple on the pseudostem and petioles. Also, the Goldfinger doesn't have colored leaf midribs. The faint red blotches on the leaf in the first picture show that it has some AAA genetics (Cavendish & Gros Michel families). The plant also looks a lot like a Namwah type, but they don't have red leaf blotches. My best guess would be either (FHIA-02) or like you were thinking, a FHIA-18. The FHIA-18 is a pretty popular variety, and I know there are quite a few people on here that grow it. Maybe they can help figure this out for sure. Hope this helps!
