Common questions

My dog eats everything in the yard — is holly fern okay there?

The fern is safe, but confirm your garden’s other plants. Actual holly shrubs, azaleas and many bulbs are toxic, so a plant inventory is worth the time for a indiscriminate eater.

Is holly fern the same as asparagus fern?

No. Holly fern is a true fern and safe; asparagus fern (Asparagus densiflorus) is a relative of the edible asparagus that causes vomiting and skin irritation in dogs.
