Here in Mississippi, zone 8b, by July we will be getting into the mid-90's, but with (always) high humidity. We'll have lots of days approaching 100 F. Two years ago we had something like 14 days above 105 F. But that's unusually hot. The combination of heat and humidity is what kills us. I don't know what the ginger would do in 115 F (with low humidity?) . All tropical plants flourish when the humidity is high. Some of my ginger gets a full day's sun, some get morning and then afternoon sun, and some get sun until about 1:00 PM and then shade. They all bloom and look the same. The cannas are all planted along with the ginger. I like the combination of fire-engine red and pure white flowers.
