Is there a swamp forum on GardenWeb? Swamp plants is what you are looking for.

Now if you want to get rid of the swampy area, someone can help with that, too.

Moist is not dry, holds together when made into a ball.
Wet is more then moist, a little water in your hand when you make a ball.
Soggy-"like corn flake left in the milk to long", you make a ball & water runs out of your hand & puddles on the floor/ground.
Standing water- after a rain the water stands for 12- 48 hours.
Standing water- a swamp- water is on top of the ground all the time, but no stream.
Joe Pye weed will live in all the above.
Wet feet means water every day or put near a water source of some kind, a dripping hose may be what you need.
At least that is what we mean here in S.C.

Dry soil is just that, dry. It has no moisture in it and most plants would die if planted in that kind of soil because they need an evenly moist soil to grow in. Most plants cannot get the nutrients they need form a soil with no moisture.
Beyond that wet, soggy, boggy, swampy, standing water are fairly synonymous. Joe Pye Weed is a bog plant.

Thanks! With my new basic understanding of wet soil vocab I'll wander of to the bog forum and find some plants for my muck.

Pitcher Plant is a good one, which I have growing wild on my
land.
Some Pitcher Plants, like Joe Pye Weed will grow in soil that are less then a Blog, but cool & well shaded.
I have seen parakeet(hooded) pitch plant, grow in the grasses medium between the North & South bound Interstate highways.
