If you are daring enough to go into the swamp you can find some great and rare plants there is a type of red wild iris or lilly down there that is not sold and is very very nice needs lots of water which down there isn't so hard (Georgia gets watering restrictions) also look for a four leaf clover no it isn't actuallya clover but it is cool grows in the swamp also wild in south georgia thru the Okee lots of cool stuff but be careful there are a few people who harvest the wild plants and sell seedlings you might keep an eye out for them rather than risk being gator bait but you won't find many of them anywhere but florida and you will get those only from a backwoods gardner type who knows what it is worth or get them yourself (it is dangerous)
