Are there deer-resistant options for shady gardens?

Prof. Samuel Fitzgerald, Ph.D.While a deer-resistant shade garden may seem like a contradiction, consider adding heuchera, whose fuzzy, tannin-rich leaves repel browsing, or brunnera, whose hairy leaves feel unpleasant against the deer's mouth.
Garden Deer Resistance. Interestingly, the defenses against grazing found in many plants, such as textured leaves that deter being chewed and unpleasant-tasting, toxic secretions, can be powerful deterrents. Several plants, such as Columbine, contain mild toxins that are harmful to humans but are avoided by animals. Devised that way by nature, gardens can survive without fencing and poisonous deterrents in deer-populated spaces.
Heuchera
- Fuzzy leaves contain tannins that deter deer browsing effectively
- Rosy-purple foliage maintains color year round in zones 4-9
- Produces airy flower spikes that hummingbirds enjoy during summer
Brunnera
- Hairy leaf texture feels unpleasant to deer preventing damage
- Silver veined leaves reflect light brightening shady corners
- Spring blue flowers fade cleanly without maintenance needs
Columbine
- Contains cardiogenic toxins repelling deer and rabbits
- Bell shaped blooms attract pollinators in spring shade
- Self seeds readily creating naturalized colonies over time
Ligularia
- Thick leathery leaves resist tearing and browsing damage
- Produces tall yellow flower spikes in mid to late summer
- Prefers moist soil conditions near ponds or streams
Design considerations also provide advantages in repelling pests. Group odor- or taste-resistant plants together and sprinkle them in unattractive zones. Place fragrant plants, such as lavender, near edges to deter deer from other areas. Use textured plants (Woolly Lamb's Ear) as a border around more appealing specimens.
Seasonal care ensures effectiveness of resistors. Water pots thoroughly, especially in dry weather, and prevent an overabundance of tender and juicy new growth: deer are especially attracted to such food. By all means avoid strong nitrogenous manures, unless you wish for close, juicy foliage. Remove decayed leaves at once, as these are attractive to wildlife in giving out sickly cries of distress.
Combine deterrent plants for a more effective result. Heuchera and Brunnera make a great combination, contrasting textures. Ajuga is a nice groundcover for filling in. You now have layers of beauty while multiplying your deterrent plants within that garden bed. I've used them this way in areas where deer heavily forage.
Keep an eye on your plants as you begin to reintroduce them, in case they show signs of having been browsed by animals. Look for ragged edges on leaves and broken-off stems. Reinforce protection from companion plants if necessary, especially since deer populations and food are seasonal.
