Here the deer are very limiting. They destroy almost everything in their path, even things that books and ingternet say they don’t touch. I’ve found some things they don’t care for, and that’s what I grow outside of fencing. Among flowers, it’s peonies, bearded irises (which don’t do well in my wet climate), daffodils, camassia, zinnias, marigolds, gladiolas, tigridia, rhododendrons, vibrunum, laburnum, forsythia, hyacinth, and of course this is not an extensive list.allium family plants - although they eat young garlic and young onion plants (or maybe that’s rabbits). I think ferns are not touched, too. Among fruit trees, they eat almost any of them, but for some reason don’t bother the Illinois Everbearing mulberry. They do some grazing on grape vines, but are not fond of them.
