The following plants will attract and encourage butterflies in Iowa. Most provide nectar for adults; others (marked with a C ) are a necessary food source for specific caterpillars. Refer to Food Preferences of Common Iowa Butterflies. Some plants support both caterpillars and adult butterflies (for example, asters, milkweeds and thistles). Inclusion of a plant does not constitute an endorsement of its use. Evaluate carefully your site and all available information before deciding to plant or retain any plants in your landscape.
