Most of the nurseries, even Sneed's, will sell cultivars as natives. This can, but won't always be, harmful to local ecotypes of our native plants because they can sometimes crossbreed. Just keep that in mind when shopping for natives anywhere. People who know what they're doing will indicate this on their inventory or be able to speak to it.

Also the natives that will be best for you will be dependent upon the conditions in the spot you'd like to plant. The local native growers can be super helpful, but you should get familiar with the moisture and light conditions in your yard. If it's your first year in this spot, note that the sun angle and quantity will change with the summer sun and foliage.
