+1. Hawaii is much closer to the equator so it doesnt have seasons like the continental US. I wouldn't be surprised if you could grow them all year round, of course they might not grow at all. More likely is that it is illegal to grow them there as they would probably take over. Dept. of Ag is pretty strict there. ever hear of the lady that brought some Lantana and now its considered an invasive pest?
