Alliums are among the most animal-resistant plants for the garden, and are a great choice if you experience deer, squirrels, moles or other critters rooting around your landscape. Their bulbs are small and not particularly tender. And, as members of the onion family, the taste of allium leaves is somewhat harsh, further putting off those grazers you may be worried about. The leaves and bulbs have a strong flavor, but are not aromatic when undisturbed, so you don't need to worry about your garden smelling like an onion patch, either. In addition to defending themselves from mammals, allium also attract pollinators such as butterflies, bumblebees, and hummingbirds to the garden. These are great plants for bringing in beneficial insects.
