Kratz, there are lists and lists of plants
you can try for butterflies! Another thing you need to think of is host plants
for the caterpillar stage. That will attract more butterflies too as the females want to lay there eggs on or near the host plant
for her babies and the males will come to attract the females for mating, well, you get the picture.
Some butterflies and caterpillars eat very specific things, for example the Black Swallowtail caterpillar will only feed on members of the carrot family, specifically parsley, dill, Queen Anne's lace, monarch caterpillars only eat milkweed plants
, others will eat clover, violets, etc. So you need that food and nectar for the adult butterfly, liatris, garden phlox, black-eyed susans, purple coneflower, asters, joe pye weed
, coreopsis,lantana and the flowers
that Thorny has mentioned and many, many more!
The butterflies at The Butterfly Place as far as I know are not released and live their entire life cycle inside.
