There are a number of plants (many mentioned already) whose essential oils repel mosquitos. The essential oils can be used in candles, diffused, etc. Or you can crush the leaves a bit and rub it on your skin or spray on essential oils. There are some nice geraniol based mosquito repellant sprays. I think it is pretty much a myth that there is any plant you can just grow and just by being there it will keep mosquitos away. The little bit of scent they give off just being there is not enough to deter mosquitos who can just fly over them.
The other part of the question, that hasn't really been addressed is attracting mosquito predators. The best are bats. You can put up a bat house to try to attract bats to your property. But bats are very sensitive to human smell, so once you have handled the bat house, it make take a year or so for it to weather enough for the bats to occupy it.
Lots of birds eat mosquitos, so having some bird feeders around will help.
And as already said, be sure not to leave standing water around for the larvae to grow in. Even a little pocket of standing water, will produce tons of new mosquitos. If you want to have a bird bath, look for a water wiggler

they come in battery and solar powered versions. It just keeps the water a little agitated, which the birds prefer and keeps the mosquito larvae out.
But mosquitos in summer in humid climates are pretty much a fact of life and mainly you have to protect yourself.
