That's about right, 5 to 7 1/2 months for FHIA-3 Sweetheart, as Richard mentioned, everything depends greatly on location and growing conditions!.....
As most of my Nanas, my main/motherplant FHIA-3 Sweetheart had a big setback, thanks to the 2017 hurricane Irma, but recovered flawlessly and put out one of my biggest Nana bunch ever!.....
FHIA-3 Sweetheart pup (second crop) was approx. 2 1/2 ft. tall in August, 2018.....Right now is approx. 11 ft. tall and keeps growing in an amazing rate!.....Looks like is stacking the leaves, it might be flowering soon!.....
