Deer and rodents can do terrible damage to tulip and crocus plantings, but there are many bulbs critters don't like, chief among them daffodils.
Below is a list of the bulbs we carry that deer and rodents generally leave alone. Please also see our list of daffodils. Only members of the Amaryllis family, which includes daffodils, snowflakes and snowdrops, are truly deer proof and rodent proof. They contain a bitter, poisonous substance called lycorine that no mammal will eat. The other bulbs in the list below are unpleasant to deer and rodents. Deer and rodents will generally avoid them but might take a bite if the plants are directly in their path or starvation gives the animals no alternative.
