Sample Butterfly Garden Certificate, suitable for framing

Frequently Asked Questions:

How big or small does my garden have to be in order to certify? All garden spaces that provide three different native nectar plants and three different native caterpillar food plants can be certified. No matter how small your location, it can help provide important butterfly habitat.

Requiring only three nectar plants and three caterpillar food plants does not seem like a very rigorous requirement. Why not require certified gardens to include more plants?NABA encourages everyone to plant a garden that will enrich the native habitat for butterflies and other pollinators. By starting with a few basic butterfly garden plants, everyone can certify a butterfly garden irregardless where they live or how much garden space they have.

NABA's Butterfly Garden Certification Program

To join NABA Butterfly Garden Certification Program, you need to create or modify your existing garden to meet the following requirements:

  • At least three different native caterpillar food plants must be grown, preferably more than one plant of each selected species
  • At least three different native butterfly nectar sources must be grown, preferably more than one plant of each selected species
  • The use of pesticides is discouraged. Pesticides can kill butterflies as well as other important pollinators.

A butterfly garden supplies food and shelter for all stages of a butterfly's life. Providing caterpillar food plants, butterfly nectar plants and about half a day's worth of sun are the basic elements of a butterfly garden.

When you certify your butterfly garden with NABA's Butterfly Garden Certification Program you demonstrate your commitment to promoting habitat for butterflies as well as other pollinators.

If your new or existing butterfly garden meets the requirements, you may either print, fill out, and mail

Please note that colors represented on computer monitors do not always reflect the true colors printed on the sign.

Although the colors in the outdoor sign should remain vibrant for a number of years, our manufacturer recommends placing the sign where it will not receive direct, intense sunlight (at least for part of the day).
