Redbud seems to be resistant.
A few years ago, I planted a small Eastern Redbud (Cercis canadensis), where the deer can easily reach it. They have never touched it, although last year they demolished a pumpkin plant right next to it, as well as every one of my daylillies this year. I live in Maryland, just outside of Washington, DC.
From the webmaster: Thanks for sharing. Redbud are listed on the "occasionally severly damaged" list from Rutgers and the deer in other places do like to eat them when there aren't better choices. My guess is that you have better choices in your area and you may or may not be safe forever. Please check our repellent recipes for you daylilies. The basic egg-peppers- etc type recipes keep them from eating mine.
