Attracting Butterflies


There’s something so enchanting about seeing butterflies flutter around your garden! You can encourage butterflies to visit your garden by providing an assortment of nectar- and pollen-rich plants. Butterflies will visit a large variety of plants but tend to prefer those with umbel shaped flowers, which provide them a place to stand while collecting nectar. Generally, any composite flower (those in the aster family, Asteraceae) is a good choice. Many weeds, including dandelion, nettle, plantain, and thistle, can also be left for butterflies to enjoy.

In addition to providing these food sources for adult butterflies, you can encourage butterflies to breed in your yard. Plant some of the larval host plants on which butterflies lay their eggs. The caterpillars then munch on these plants until they are ready to form their chrysalises. Be prepared though – these plants will get eaten! You can plant host plants away from the rest of your garden to prevent caterpillars from munching on other plants, but there’s no need to be too careful, most species will only feed on specific plants. For best results, plant your host plants and nectar plants close together or mixed in the garden. 

Butterflies also like to bask in the sun during the cool mornings. Provide them a place to do this by placing some large, flat rocks in a sunny spot. You can also provide butterflies with a place to drink water. While they cannot drink from open water, filling a shallow container with wet sand will allow them to perch and drink happily.
