Deer often visit gardens in search of food, and frequent grazing can take a toll on your prized plants. Fortunately, there are several deer-resistant plants that you can add to your garden, like nodding wild onion. Also known as lady's leek, the nodding wild onion (Allium cernuum) is a perennial onion native to North America. As a result, whether you're looking to start your own pollinator garden or simply add a splash of color while keeping deer at bay, nodding onion can be a beneficial addition. Thankfully, learning to grow nodding onion can be as simple as familiarizing yourself with its USDA growing zones (4 through 8), sunlight requirements, and other key care essentials.
