WOOT WOOT! More Iowa people!!! Welcome to the site. I'm Bryan, I'm from Mount Vernon, Iowa but I'm going to school in St. Louis, MO right now. Hope you enjoy the site and your banana growing experience. Just to clarify,
Ensete Ventricosum is the 'Abyssinian banana' and is a seeded variety (ornamental and considered non-edible unless you want to eat around super hard seeds). They get up to about 20 feet tall and will take 4-5 years to fruit. Just so you know, this is not a Musa variety like the package says. I'll spare you the entire explanation but suffice it to say that banana varieties fit into three categories: Musa (bananas), Ensete (false bananas) and Musella. Therefore, an Ensete is not a Musa and vice versa. Hope the information is helpful (and I linked the wiki page about it above for your viewing pleasure).
Hope you have great luck with your plants! This site is full of great resources and knowledgeable people so if you have any questions, just ask!
