There are two types of florida blue garter. One is actually an eastern garter, Thamnohpis sirtalis sirtalis, and is basically a blueish color morph of the eastern. The other is the true Florida Bluestriped Garter, Thamnophis sirtalis similis. Dekaybrown owns four "florida blue" eastern garters, which came from my female. Florida blue easterns can grow up to be really blue, or not blue at all, but either way they have a distinct look. Florida Bluestriped Garters have a distinct look also, and vary in what shade of blue they are and how intense. I keep both the easterns and the florida bluestripes, and while they are both profound eaters, the florida bluestripes (similis) are definitely the nastiest subspecies of garter I have ever encountered and I have heard that from pretty much everyone. They are very wiry and will flip out at the slightest movement, and are very prone to biting and suddenly spitting out their food and freaking out. Scott Felzer himself agreed with me on the phone that they are extremely flippy snakes. 9 times out of ten, when you see "florida blue garters" for sale on KS, is it a wholesaler that has some WC garter snakes from florida and does not know jack squat about them other than they are blue.( o0o00o0ohhhh. ) If you email them and ask which subspecies and they can't tell you, run far far away. The Bluestripes, or similis, are harder to come by and you are best going with CB specimens either way if it's possible. The "stunning blue garters" Dekay brown mentioned are referring to an ad often posted on KS by a man named Bob, and the snakes in question are labeled as Puget Sound Garters,(pickeringii) but are also sometime actually Blue Northwestern Garters (Ordinoes) and he actually has no idea. That's another guy to stay away from, he has sold a lot of really unhealthy snakes (they are WC) to a lot of people including myself a few years ago when I had no idea what i was doing. Puget sound garters and blue northwestern garters are both stunningly blue, but re from the opposite side of the country. I hope this helps you sort out a bit about blue garters!!! and I dont have time to re-read my post so I hope it all makes some bit of sense!
