Experts and BHG readers answer.
deer resistant plants
Thanks for writing. No plants are truly deer proof, but some that deer tend to pass by include highly poisonous varieties (monkshood, hellebore, castor bean); plants with very fuzzy or hairy foliage (lamb's ears, brunnera, etc.); or plants that have strongly scented leaves (yarrow, bee balm, herbs, etc.).
