When to Plant Daffodils in Pennsylvania

Deer-proof, squirrel-proof, and virtually indestructible. Daffodils naturalize and multiply, coming back bigger each year.

The Short Answer

Daffodils are Pennsylvania's most reliable spring bulb — they naturalize in the state's cold-winter climate, multiply without replanting, and are ignored by the deer and squirrels that ravage tulips.
