Want to see more butterflies? Plant a butterfly garden!

The most successful butterfly gardens include a variety of host plants (food sources for butterfly caterpillars, which draw in adult butterflies who want to lay eggs on them) and nectar plants (food sources for adult butterflies). Native plants are ideal both because they are best suited to survive in your region and because they are the best food & habitat sources for your local butterflies.
​
Check out our Butterfly Garden & Landscaping Tips for more ideas and recommendations! On this page, you will also find some ways to make your outside space more butterfly friendly no matter what landscaping you have.
 
See below for a list of some plants we recommend for home landscapes that support butterflies and other pollinators in and around Central Illinois. Most of these plants are tough, native species that grow well in our area, but a few non-natives are listed as well. 
​
Note: some of these plants – especially the flowers such as purple coneflower – are often available as horticultural cultivars from garden centers and big box stores. These cultivars have usually been bred for appearance rather than usefulness for butterflies, so planting the “wild” varieties from nature centers and native plant outlets is best (see our list of potential sources). â€‹

BEWARE!

Plants from large nurseries have often been treated with systemic insecticides that are incorporated into the plants and may harm the very animals you are trying to help!

UBI Quick Guide to Butterfly Gardening

  • Use plants that are 3 feet tall or less. Patches with all tall plants may look more ‘wild’ than you or your neighbors desire, so in locations where this may be an issue, use shorter plants for most of your butterfly landscape (see Short Flowering Plants below).

  • Have a border of some type. Borders such as a path, line of rocks or timbers, etc, can help make your butterfly area look ‘intentional.’

  • Beware of turf grass around the edges of your planted area. Most turf grass is extremely aggressive and will quickly invade your native planting, making the landscape look more “weedy,” competing with the natives and increasing maintenance.

  • Pros and cons of planting seeds. Using seeds is slower but much more economical than buying already started plants. Plant starts will often bloom the first year, while plants grown from seed will sometimes take a year or two (or sometimes longer) to get mature enough to bloom. Keep in mind that most native seeds also need to overwinter in the ground (or in damp sand in the refrigerator for 1-3 months) to break dormancy. Prairie Moon Nursery is a great online resource for individual plant needs, site preparation, and planting technique.

  • Plant some of the caterpillar host plants as well. Without food for their caterpillars, there will be no beautiful adults! These plants also draw in adult female butterflies looking for a place to lay their eggs as well as adult male butterflies looking for females. See our Recommended Butterfly Plants below.

  • Include native grasses (see Grasses below) in your design to fill space between flowering plants. Bare ground means more unwanted “weeds” and more maintenance. The best butterfly garden designs consist of integrated plant communities, not isolated plants separated by mulch. If you’re interested in reading more about this design concept, check out the books: Garden Revolution (L. Weaner & T. Christopher), Planting: a New Perspective (P. Oudolf & B. Kingsbury), and Planting in a Post-Wild World (T. Rainer & C. West).

  • Try to plant your garden in a sunny area. Most of the flowers and grasses listed do best with at least 6 hours of direct sun per day.

Happy gardening!!

No matter what your yard looks like, whether you have a butterfly garden or not, or even if you rent or live in an apartment, you can make your outdoors more butterfly friendly without even changing your landscaping!
 
Butterflies are very sensitive to toxic chemicals, even those that drift over from nearby areas. Many butterflies also feed on the flowering "weeds" that often get sprayed in lawns, such as clover.

​
Flowers from the "weeds" in your lawn get cut off by mowing, removing a vital food source for butterflies. Also, some caterpillars feed on grasses, and the higher you cut, the more likely they are to survive the mowing.

​
Many butterflies don't migrate, but instead stay where they are and overwinter as pupa or adults. To survive the cold temperatures, they often hide in fallen leaves or rely on the layer of leaves to insulate the soil. Leave the leaves! xerces.org/blog/leave-the-leaves
​
Artificial light at night messes with the internal clocks of monarchs and disrupts their navigational abilities. It also interferes with the normal mating behaviors of many moths, including the gorgeous luna moth!
