Choosing Plants for a Butterfly Garden

Butterflies need two types of plants to survive: the host plant and the food plant. Attracting butterflies to your garden takes more than just planting a few flowers for nectar because most people only focus on this one thing. One of their worst mistakes is planting alien, non-native plants that are often promoted as being good for butterflies when they actually aren’t! To have beautiful, healthy butterfly populations again in North America we need to replace our lost native host plants with species like buddleia bushes – it’s all about providing what these amazing insects need!

Butterflies Need to Lay Eggs

Butterflies lay their eggs only on the plant species to which their larvae are adapted. Their larvae only feed on the plants that are appropriate for them as caterpillars. Caterpillars, in turn, become either a new moth or butterfly, or a source of food for birds.

Here are some plants you can use to attract butterflies. Willows attract viceroys; black cherry trees attract tiger swallowtails. Viola feed fritillary butterflies. Virginia Creeper enables the Pandora sphinx to reproduce. Oaks provide food for the polyphemus moth and others. Flowering dogwood (Cornus florida) and any of our native Viburnums hosts the spring azure (Celastrina ladon), an early spring butterfly.

Butterflies Are Good Pollinators

Pollination is essential to plant life, and only about ten percent of plants are self-pollinating. All the rest need butterflies, bees and other pollinators to help them reproduce. As pollinator populations fall, we are more and more at risk of losing entire species of plants.

Without butterflies and other pollinators, many food crops, flowers, and wild plants would be at risk of dying out. Losing these plants would negatively affect people and the natural world. [source]

In addition to helping plants pollinate, butterflies also help ensure the genetic strength and diversity of plants because they travel long distances in the course of their lives.

They carry pollen from one population of plants to another, and this helps plants to better resist disease. When plants are strong and healthy, they also resist pests, so butterflies are instrumental in helping control plant pest populations.

Butterflies Are A Tasty Meal!

Although some butterflies (e.g., Monarch butterfly) are bad tasting and poisonous when ingested, many are important sources of food for birds and other beneficial wildlife.

When butterfly populations drop, so do the populations of animals that eat them. Negative impacts on plant and animal populations have a domino effect throughout the food chain and can cause the complete collapse of ecosystems.

Planting A Butterfly Garden Is Fun & Helpful

It’s easy to see that butterflies are more than just a pretty face. When you select plants especially to attract these useful insects, you beautify your immediate environment and benefit the environment as a whole.

Here are 17 of the best plants you can choose to create a stunning butterfly garden.

10 Tips For Creating A Safe, Inviting Butterfly Garden

Butterflies may come for the flowers, but if other conditions are not right, they may not have a successful visit. Here are ten things you can do to be sure your garden is safe for butterflies and conducive to butterfly reproduction.

• #1 – Avoid pesticides. Turn to natural pest control – especially in your butterfly garden. Stay away from poisons like Sevin, diazinon, and malathion as they will kill off everything, including butterflies.
• #2 – Include native plants as often as possible. Learn about wildflowers and natural plants that thrive in your area. Creating a native plant garden or adding native plants to your garden makes a pretty, easy-care butterfly attraction that will also support other beneficial native fauna
• #3 – Take advantage of the sun. You’ve probably noticed that all the plants listed love full sun. Even if you only have a little space, such as a sunny deck or balcony, use it to its best advantage to encourage and support butterflies. They love the sun, and often will only feed in areas that have full sun.
• #4 – Pay attention to your color combinations. The brighter the colors, the more attractive your garden will be to butterflies. They especially like purple, pink, orange and yellow. Red is also a favorite with both butterflies and hummingbirds.
• #5 – Pay attention to shape. Flowers with flat tops and those that with short flowering tubes are the most accessible for butterflies.
• #6 – Choose your milkweed well. Learn about the types of butterflies in your area and the types of milkweed that are native to your area. Be sure to plant an ample amount of your native milkweed to accommodate your native butterflies. Add other types for color and interest, but understand that they may not be edible or useful as host plants for your local butterflies and caterpillars.
• #7 – Set up butterfly baths. Butterflies like birdbaths, but there is always the risk they might fall in and drown. That’s probably why they prefer to “puddle.” They like to rest, relax and drink water in puddles of mud or damp sand. To provide this, fill a plant saucer or other shallow dish with sand and water to provide a safe cooling and drinking place for butterflies. Change the water every day or two.
• #8 – Set up sunbathing areas. Butterflies like to bask in the sun, so be sure your garden has some flat surfaces for them to alight upon. Flat rocks, tables and lawn furniture are all good choices.
• #9 – Remember butterflies are for looking, not touching. Enjoy watching them wild and free, and teach your children to do the same. Don’t catch them to look at them as they are delicate and can be badly harmed or killed by handling. When you kill a butterfly, you are also killing all of its offspring.
• #10 – Learn the difference between pest caterpillars and butterfly caterpillars. Take a little time to learn to recognize the offspring of your local butterflies. If you have a good butterfly garden, they are unlikely to turn up in your veggie garden. If they do, simply transfer them to their own space to live and grow in peace.
