Choose Your Target Butterflies

Research the butterfly species native to your area. This will help you select the right host and nectar plants.

Local Species: Contact your local nature center or butterfly club to learn about the butterflies in your area.
Host Plants: Identify the host plants for your target butterflies. These are the plants that caterpillars feed on. For example, Monarch caterpillars feed exclusively on milkweed.
Nectar Plants: Choose nectar plants that bloom at different times of the year to provide a continuous food source for adult butterflies.

Design Your Layout

Create a rough sketch of your refugium. Consider the placement of plants, pathways, and other features.

Plant Grouping: Group plants with similar needs together. This will make watering and maintenance easier.
Pathways: Include pathways to allow easy access for weeding and observation.
Shelter: Provide sheltered areas where butterflies can rest and escape from predators.
Water Source: Incorporate a shallow dish of water with pebbles for butterflies to drink from.

Step 2: Selecting the Right Plants

The plants you choose are the heart of your butterfly refugium. Select a variety of host and nectar plants that will provide food and shelter for butterflies throughout their life cycle. Native plants are generally the best choice, as they are adapted to your local climate and support native butterfly populations. The Xerces Society is an excellent resource for finding native plant recommendations.

Host Plants

Host plants are essential for butterfly reproduction. These are the plants that caterpillars feed on. Without host plants, butterflies cannot complete their life cycle. Here are some examples of host plants for common butterflies:

Monarch Butterfly: Milkweed (Asclepias spp.)
Black Swallowtail Butterfly: Parsley (Petroselinum crispum), Dill (Anethum graveolens), Fennel (Foeniculum vulgare)
Spicebush Swallowtail Butterfly: Spicebush (Lindera benzoin), Sassafras (Sassafras albidum)
Painted Lady Butterfly: Thistle (Cirsium spp.), Mallow (Malva spp.)
Question Mark Butterfly: Elm (Ulmus spp.), Hackberry (Celtis occidentalis)

Nectar Plants

Nectar plants provide food for adult butterflies. Choose a variety of nectar plants that bloom at different times of the year to provide a continuous food source.

Butterfly Bush (Buddleja davidii): A popular choice, but consider native alternatives in some areas.
Zinnias (Zinnia elegans): Easy to grow and available in a variety of colors.
Coneflowers (Echinacea spp.): Native to North America and attractive to many butterfly species.
Asters (Symphyotrichum spp.): Late-blooming flowers that provide nectar in the fall.
Lantana (Lantana camara): A colorful and long-blooming option in warmer climates.

Creating a Blooming Schedule

To ensure a continuous food source for butterflies, plan your planting to provide blooms throughout the growing season.

Season	Plant Examples	Benefits
Spring	Phlox, Columbine, Lilac	Provides early nectar for emerging butterflies.
Summer	Butterfly Bush, Zinnias, Milkweed	Offers abundant nectar during peak butterfly activity.
Fall	Asters, Sedum, Goldenrod	Supplies nectar for migrating butterflies and those preparing for overwintering.

Step 3: Preparing the Soil

Healthy soil is essential for healthy plants. Before planting, prepare the soil by removing weeds, amending with compost, and ensuring good drainage. Proper soil preparation will give your plants the best start possible. Many Cooperative Extension offices offer low-cost soil testing.

Remove Weeds

Clear the area of weeds and grass. Remove the entire root system to prevent them from growing back.

Amend the Soil

Add compost or other organic matter to improve soil fertility and drainage. Work the amendments into the top 6-12 inches of soil.

Ensure Good Drainage

Butterfly plants generally prefer well-drained soil. If your soil is heavy clay, consider adding sand or gravel to improve drainage. Raised beds can also be helpful.

Step 4: Planting Your Butterfly Refugium

Now it’s time to plant your butterfly refugium. Follow these tips to ensure your plants thrive:

Planting Time: The best time to plant is usually in the spring or fall, when temperatures are mild.
Spacing: Follow the spacing recommendations on the plant labels. Give plants enough room to grow and spread.
Watering: Water plants thoroughly after planting. Keep the soil moist but not soggy until the plants are established.
Mulching: Apply a layer of mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature.

Step 5: Providing Water and Shelter

Butterflies need water and shelter to survive. Provide these essential resources in your refugium to create a welcoming environment. A simple butterfly puddler can be created with a shallow dish and some wet sand. The U.S. Forest Service provides more information about creating pollinator-friendly habitats.

Water Source

Provide a shallow dish of water with pebbles or marbles for butterflies to drink from. The pebbles provide a safe landing spot.

Shelter

Plant shrubs or trees to provide shelter from wind and predators. Butterflies also need sunny spots to bask and warm up.

Basking Spots

Place flat stones or rocks in sunny areas where butterflies can bask. These basking spots help butterflies regulate their body temperature.
