Pest Resistant Bulbs and Perennials
Pest-Resistant Bulbs and Perennials: Beautiful Solutions for Critter-Prone Gardens
Nothing dampens a gardener’s enthusiasm like waking up to chewed tulips or vanished hostas. Fortunately, many bulbs and perennials are naturally unappealing to deer, rabbits, and other common pests. Whether you’re designing for a rural property or a suburban yard on the edge of a woodlot, pest-resistant planting can deliver both beauty and peace of mind.
Why Pest Resistance Matters
Deer, rabbits, and rodents often browse plants based on taste, fragrance, and texture. Some plants produce bitter alkaloids or have sap, aroma, or physical characteristics that make them less palatable. While no plant is entirely “deer-proof,” choosing resistant varieties reduces risk and helps preserve your investment.

- Elevate early bulbs: Containers or raised beds can keep bulbs safer from voles and rabbits.
