I find that most sellers list SF., but send a DF and call it a bonus. That works for me. Except for intro's. They are usually lrg. Sf.
If I do get an actual Sf., i wont order again. I have terrible luck with sf., . Now if I go to Nicoles, or over to Floyd Cove, and a single fan is busting out of a 5 gallon pot, thats a different ball game. I got some sf's., from up north this spring, they just could not take the heat. Even in the shade they struggle.
