Ever since my friend sent me the photos of his natural defense against deer damage in his garden, I’ve been giving fresh thought to the fairly wide selection of deer-resistant conifers. Last winter I approached this topic with fairly broad generalities, simply referring to conifer species that have shown resistance. Today, I’d like to take another look at deer-resistant conifers from a regional perspective by listing conifers that have been successful in different parts of the country.
A great example is from my friend in the Mid-west. In his experience, living in rural eastern Iowa, Picea pungens cultivars have been very deer resistant. That includes both the larger and dwarf forms such as the larger, ‘Fat Albert’ and ‘Hoopsii’ as well as dwarf forms such as, ‘Lundeby’s Dwarf’ and ‘St. Mary’s Broom’. He also noted that although the deer absolutely love his Eastern White Pine cultivars (Pinus strobus), they seem to stay away from Pinus mugo ‘Tannenbaum’, an intermediate sized, broad tree-form of the Mugo Pine. In his area, the deer also tend not to bother with Thuja plicata (Western Red Cedar).
My friend on Long Island, New York has found that all of the Colorado Blue Spruce (Picea pungens) are resistant to deer damage. Unfortunately, some conifers that folks in others regions have had success with, such as Cephalotaxus and Thuja plicata ‘Green Giant’, seem to taste just fine to the deer in his area.
My friends living in various locations along the mid-Atlantic area have found cultivars of Thuja plicata to be resistant to the herds in their region. They have also noted little damage from deer on the cultivars of Cryptomeria japonica (Japanese Cedar) such as ‘Black Dragon’, ‘Kitayama’, or ‘Sekkan’. The Oriental Spruce (Picea orientalis) shows resistance in this area whereas the Norway and Colorado spruce (P. abies and P. pungens) only somewhat. Cephalotaxus (Plum Yew) and Thujopsis (Staghorn Cedar) show some resistance in this region.
One conifer that none of my friends have ever seen bothered by deer is Sciadopitys verticillata (Japanese Umbrella Pine) and its cultivars. (Update: one of my friends does report some deer damage to Sciadopitys in her section of Connecticut. See comment below.)
Of course all of my friends emphasize that it depends on the size of the herds, the severity of the winter and availability of other foods. As noted in my previous post on this topic, natural defense can go a long way to prevent deer damage. Man’s best friend can also be a deterrent to deer entering the property – many dogs love a good chase after four-legged trespassers.
