Welcome to the Bunch. ... A
Gros Michel is not a good choice for you.
Orinoco,
California Gold or may be a
Namwah would be better suited for your first time. The GM is very temperature sensitive and difficult to grow even in Florida north of zone 10.
I think you may be in growing zone 8 due to the warmer coastal breeze. I'm in 8a in south Georgia. I lost 4 GMs that I planted in the November of 2016. The corms didn't make it through the winter. ... So you would need to grow your GM in a green house; or dig it up each fall to over winter in the garage with a min. temp of 45 deg. F
