Answer: Deer are a real problem on many plants. Lists of deer-resistant plants exist but if they are really hungry they'll eat just about anything!
Sprays of egg solids, hot pepper oil and other such ingredients are available and may help some, especially when the deer "pressure" is not too high. Human hair (from the local barber shop) in bags made of hosery and perfumed soaps have worked for me when they had other options to feed upon.
Some plants not especially attractive to deer include:
Abelia grandiflora, Arctostaphylos (manzanita), bamboo, barberry, Buddleia, boxwood, Callistemon (bottlebrush), Cistus (rockrose), heather, cotoneaster, Acanthus, Aquilegia (columbine), Artemisia, Chrysanthemum, Coreopsis, ferns, Dicentra, thyme, viola and Zantedeschia (calla).
Hope your garden resists raiding from the local wildlife!
