Butterflies Prefer Natives!

Nectar Plants

There are many foods one can “survive on,” but we do have our favorites. Butterflies are no different. Many flower types will attract a few dining butterflies, but the dinner fare offered up by native plants for both butterflies and their caterpillars is tops! Studies have shown that native blooms and leaves attract many more butterfly species and individuals than their non-native counterparts.

The nectar sipping apparatus of butterflies and other pollinators are well matched to the native plants with which they have co-evolved. Highly modified horticultural varieties can lose characteristics that originally guided a pollinator to its food, or they may lose their nectar and pollen entirely.

Among the most well known and popular plants for Butterfly Gardens include Blazingstars (Liatris) and Milkweeds (Asclepias) for Monarchs, but there are numerous other choices. To create your own butterfly restaurant, choose nectar plants with bloom times throughout the growing season: Lupine and Phlox in spring through Asters and Goldenrods in the Autumn.

Host Plants

While many native plants serve as general nectar sources, host plants for butterfly caterpillars can be absolutely specific.

Providing host plants plays a role in attracting these colorful pollinators to your landscape. Here’s a butterfly-centric list with prefered and/or exclusive host plants. Add host plants to your butterfly garden and see who shows up for dinner!
