What temperature zone(plant hardiness) are you in?

Isnt Key Largo south of Miami? You most definately are in zone 11, check up wunderground com and the temperature history. Even West Palm Beach is zone 11 because the average annual minimum is about 40 degrees and its essentally frost free, in other words tropical. Where did you get zone 10 from? That is old, outdated info.

plenty of inter-annual minimum temperature variability here in Indianapolis,Indiana as you can see for the last 23 years of data, I have researched and have even more annual minimum temperature data dating all the way back to the winter of 1956-57.

-118 Divided by 23 years=-5.1 Degrees, just barely missing the transition cutoff point between 6-a and 6-b, so I would say that Indianapolis Indiana is a bit more solid zone 6-a than what is shown on the 2012 USDA Hardiness Map, since 2005 is 8 years off and the new 30 year normal would be from 1984 to 2013, but I would keep the period back to 1976 and add to this data set to be sure and these zones are subject to change, and the longer data point the better an idea one might have for one's own zone. Data from 1983-1984 to present= Negative 174 Degrees, Divided by 30= 5.8 Degrees Below Zero, which is 1.7 Degrees warmer than 1976-2005, however; Negative 230 Divided by 38= about 6 Below Zero, so Based on Data from 1976 to 2013 or 38 years of averaged data shows that Indianapolis is a Plant Hardiness Zone 6-a although a fairly more solid Zone 6-a if a map were to be drawn because the 1976 to 2005 is about 1.5 Degrees colder than the 38 year data set is, and the more recent 30 period from 1984 to 2013 is 1.7 degrees warmer than 1976-2005 data set is;So I would say I am located in a comparatively solid Zone 6-a,at least for the time being, and based on the AVERAGE and ONLY the AVERAGE lowest TEMPERATURE I EXPECT to happen each winter here in Central Indiana. Also based on the temperature data set from 1957 to present day the average minimum temperature for the 56 year period is about 7.2 Degrees Below Zero so after an additional 18 years of data were added, Indianapolis is in planting zone 6-a. The 13-year data set for Indianapolis from 1974-1986 yielded an average annual temperature minimum of 10.2 Degrees Below Zero-Barely even cold enough to be classed a Zone 5-b based on the data calculated.
