There are several lists of "deer-resistant" plants on the internet. This site has many compiled lists from many states. Before deciding on which deer resistant plants to buy, you need to decide which list of plants to consult.
The first thing to consider is the state you live in. It must be state specific, or a compiled list.
Second, look for specifics. Just having one list and saying that deer avoid these plants isn't good enough. The plant lists should include 3 or 4 groups of feeding preferences (i.e. Rarely, Seldom,Occasionally, and Frequently Damaged).
Consider who is generating the list and what they have to gain. Was the list generated by the extension service or other government agency, or a site like this one that is generating information, or was it created by a business selling resistant plants. Just be careful which list you are consulting.
Look for lists that have plants grouped as trees, shrubs, bulbs, etc. unless you know your plants. While it is true that a shrub in one state could be a tree in another state, or an annual will be perennial in the deep South, it is still good to have an idea of what is being suggested. This will give you the information you need to look for the plants at a nursery or plan a landscape.
