This guide is not a guarantee.  Deer will eat almost anything when they are hungry.  Their preferences vary from herd to herd, and the denser their population, the more adventurous their appetite becomes.  Even if a plant is ‘deer resistant’ they may still nibble the flowers.  Look around your neighborhood to see what is surviving there.  When bucks are shedding the velvet on their antlers they will rub them on any tree or shrub available causing damage.  The best deer proofing is an eight foot fence!
