Augusta is temperate, not subtropical imo. You have to get down to within 50 miles of the coast to see more of those specimens. However, it is way more green and alive looking in Augusta in winter than say Philadelphia or New Jersey.
I've come to believe that the only major weakness of Koppen is with the Cfa zone and that the rest of it works well. The Cfa issue could be addressed simply by dividing the zone in half along the 9°C isotherm for the coldest month; at that point the system would be perfectly functional for any practical purpose.

That change would separate places like Philadelphia and Augusta from places Tampa and Orlando. Obviously it leaves Augusta together with Philadelphia but most people could probably live with that.

That is exactly what the below map does.

Note that these are 20 year old normals so the line has moved further North.

That map seems to do a lot more than just divide Cfa in half.

Europe is more stable than NA, but it can get hit with severe cold from Russia that blasts all the way to southern Europe like in 2012 and in the 80's.
I've wondered the same thing at times but...

Let's just say more like to succumb to diseases and perish than typ subtropical species further south.

See below Savannah GA on a January day (mean Jan temp of 51F). TBH, that looks similar to the amount of green and bright sunshine you see in S FL in winter:

...then I've come to understand all the goodness Koppen brings in other areas and have decided (see my other post) that just splitting Cfa in half along 9°C (or 10°C) would be a more elegant approach.

Savannah is subtropical, no doubt about that.

I still say 6°C is the proper divide

Augusta like Philadelphia, give me a break,.
Augusta is much closer to Florida in basic vegetation, Augusta is pine dominated just like the rest of the coastal plain but I see you cherry picked a winter photo that you think supports your point.

I didn't actually say Augusta was closer to Philadelphia than Florida. I said that dividing Cfa in half leaves Augusta stuck with Philadelphia. Not ideal perhaps but certainly a better outcome than grouping Philadelphia with Tampa.

The basic forest type is the same for Augusta and the rest of the southern half of Georgia, pine forested with bald cypress in swampy areas. The CIDPs that are growing here look very good, only washingtonia robusta starts burning in the low 20s but they look like that in Savannah and Brunswick too, what's your point. My family's from the Charleston area, I used to visit there every weekend in the '90s, it didn't feel like I was entering another climate zone going there, it's nearly identical to Augusta/Aiken in fact.

You are not consistent, you want to eliminate as much of the south from being subtropical as possible, so you might include the coastal area. I've read through your older posts and you are just completely schizophrenic.
You like to cherry pic photos to judge an entire area, you'll cherry pick a photo from say Charleston and contrast it with a photo from the "dead inland south" and it is just ridiculous. Then you'll cherry pick a photo from like Australia or South America and contrast that photo with deciduous winter scenery from Charleston.

Humid subtropical means 8 months above 50, Trewartha came with the term but many are trying change the definition without any consistent methodology at all.

Oh does that mean Augusta is in league with Houston and Galveston with their snow covered landscape this year, I mean you cherry picked a snow photo of Augusta. I'll have to start using troll logic too.

With a coldest month of 8.6°C, I group Augusta in my subtropical definition. I use a coldest month between 6°C and 17.9°C, and 4 or more months with a mean 18°C+
