Kathy, the Iris will be fine as it is a hardy plant. As for the Water Hyacinth, so long as it does not freeze it should be okay. If it is forecast to go below 0°, I would suggest you put them into a bucket of water in the garage or shed overnight. Should you have a frost at night/early morning in your area, just lightly spray the plants with water from your hose prior to the sun shinning on them and that will wash the frost off the leaves and stop any damage being done.

I have a tree my checkbook hates. It is a 50 year old spruce, decidedly generic in nature, it looks like what you might get if you crossed a Norway and a Blue Spruce and took the worst attributes of each. It has blown up the driveway. It is hanging over the house and threatening to crush it. It has a huge divot half way up taken out by the electric company. We had a foot of very heavy snow a couple days ago, a truly windless dump. A branch high up broke falling straight down taking out the branch below it and continuing on until the train reached the ground. Nine major limbs removing an entire section of the tree. Like a slice out of a pie. The only good thing was it chose the only possible section of the tree where that could happen and the resulting 5' tall pile of limbs didn't actually crush anything. Only thing it does do is keep the house cool in the summer. One of these days it is going to be firewood but removing it will cost a fortune.

I'm in the Atlanta metro area. I have lamium outside and it isn't evergreen but it does come back in the spring. I even have some in a container that has come back for several years.

I'm not sure, but don't think this is permitted. We don't normally sell cuttings, we swap them (that's what's preferred) or sometimes exchange plants for the cost of their postage, but selling plants outright, is, I believe, not permitted. For that, you really need to go to a nursery or your local plant shops or box stores.
