I have found that different lists feature different plants. University of Minnesota Extension’s list of deer resistant plants includes yarrow, allium, coneflower, peony, poppy, Russian sage and salvia for sunny spots. Columbine and geraniums will work in either sun or part shade. On other lists, you will find ajuga, astilbe, bergenia, bleeding heart, brunnera, coral bells, ferns, helleborus and lungwort for shady spots. It seems that deer resistant plants have thick or coarse foliage in common. If the foliage looks like lettuce, avoid the plant as the deer will love it. Go with hairy, fuzzy, coarse textured and thick foliage plants instead.
Thanks for writing!
