No one will give you a guaranteed list of deer-proof plants. The plants on a list will change with the weather and the garden. There are plants that wind up on more lists than others. Bluebonnets and zinnias are believed generally safe unless weather conditions decrease preferred plants. I would like to have a clone of this plant in my yard.
Seeds can be testy, however, so try rooting cuttings at home.
Plant cuttings in containers filled with a well-draining soil mix. Mist from time to time. Keep the soil moist but not soggy. Give the cuttings a gentle tug in a month to see if they have rooted. If not, give them another month to do so.
