Venue for a garden wedding

Any suggestions for a garden wedding in southern states (Georgia, The Carolinas, Tennessee)? I originally wanted a botanical garden wedding but there's SO many restrictions for that. I don't want a venue that requires the use of their venders, both for the cost and because I'm vegan but my fiancé isn't so we need control over the food options. Does anyone know of a place that has a either a botanical garden or fairy garden feel for the ceremony but is flexible with options for the reception hall?

Other relevant info:
Our ceremony is very intimate, only parents and the bridal party so we won't have seating or much decor
The reception will be around 50 people so again we don't need a ton of space
