'Deef-proof' plants do not really exist, except for the very poisonous and extremely thorny, which are usually not what we desire in our personal landscapes. But there are many plants which deer tend to avoid, year 'round or depending upon the season and what else is growing around them. Avoiding 'target' plants which deer clearly love is very important - once they come down to sample these, they often do damage to other neighboring plants as well. By the same token, planting many species which they find unpalatable will help to 'hide' other species which they have been known to enjoy. It is an ongoing challenge prone to regional differnces, but the plants listed here are generally known to be 'good risks'.
