Gardening for Butterflies. Because butterflies are attracted to flowers, it is easy to plant a garden that both you and they can enjoy. Some of the species you may attract are listed in the table at right. A butterfly-friendly garden contains both adult nectar plants and caterpillar host plants. A few common vegetables also serve as caterpillar host plants. Many butterfly gardeners plant extra vegetables, enough for them and their caterpillars. As an added bonus, butterfly gardens often attract hummingbirds.
Butterflies and moths use specific host plants. The host plant is the plant or plants that specific species of butterflies or moths can eat. For example, Gulf Fritillary caterpillars eat only specific passionvine plants. Butterflies with a short proboscis cannot drink nectar from a flower with a deep throat and nectar at the base of the flower. Some butterflies seem attracted to specific flowers and/or colors.
