Butterflies are fascinating to watch and relatively easy to attract to your yard. Plant your butterfly garden in a sunny spot and be sure not to use pesticides. In order to maximize the number of butterflies coming to your garden, you should provide plants for both the winged adults and the less well known larval form, the caterpillars. Additional features that butterflies will appreciate include flat rocks for basking and a damp mud puddle or area of moist sand (many butterflies seek moisture and minerals from such areas). Certain species may be attracted best by putting out an occasional piece of overripe fruit.

Below is our Top Ten list of some of the most common and easy-to-attract butterflies for North Carolina. Each is shown along with the host plant(s) most preferred by their caterpillars. Although many host plants can be purchased from a nursery, others are best grown from seed or should be protected if found growing near your garden.

Top Ten ButterfliesHost Plants
American LadyEverlasting, Pussytoes, Cudweeds (all are plants common to grassy areas and disturbed sites)
Black SwallowtailParsley family (Bronze Fennel, Dill, Parsley, Carrots, Queen Anne's Lace)
BuckeyePlantain, Snapdragons, Purple Gerardia
Cloudless SulphurWild Senna(Cassia sp.)
MonarchMilkweed family; especially Butterflyweed (Asclepias tuberosa) and Swamp Milkweed Asclepias Incarnata)
Pearl CrescentAster species
Red-spotted PurpleWild Cherry*, Willow*
Silver-spotted SkipperWild Cherry*, Willow*
Spicebush SwallowtailSassafras*, Spicebush
Tiger SwallowtailWild Cherry*, Tulip Poplar*
*Trees in butterfly gardens are best kept closely cropped, both to keep them from shading out the flowers and to make it easier to find caterpillars on them!

Below is our list of the Top Ten easy-to-grow, sun-loving plants recommended as excellent general nectar sources for adult butterflies in our area (consult local nurseries for availability);

Black-eyed Susans (Rudbeckia hirta and other Rudbeckia species)

Butterfly Bush (Buddleia sp.); not native

Cardinal Flower (Lobelia Cardinalis)

Goldenrods (Solidago sp.)

Ironweed (Vernonia noveboracensis)

Joe-Pye weed (Eupatorium purpureum)

Milkweeds (especially Butterflyweed (Asclepias tuberosa) and Swamp Milkweed (Asclepias Incarnata)

Ox-eye Daisy (Leucanthemum valgare; formerly Chrysanthemum leucanthemum)

Purple Coneflower (Echinaecea purpurea)

Verbena (Verbena hastata and various other species)

Note: Most of these plant recommendations are species native to North Carolina. We encourage the use of native plants in your landscape for several reasons:

Local wildlife is generally better adapted to using native plants so efforts to attract wildlife may prove more successful.

Teaching children about local plants helps give them a sense of ownership to their local environment. Once they begin to know and appreciate wildflowers and native trees and shrubs, they are more likely to care about preserving them.

Native plants are adapted to local conditions and generally require less maintenance. They are also more likely to be resistant to local pest populations.

Native plants provide teachers with a wealth of teaching tools from natural history information to folklore and cultural uses (edible and medicinal properties, etc.). It is also generally easier to locate resource information about native species.

The planting of native species is ecologically important and serves as a model of habitat conservation for students.
