Native Butterfly Plants in Pennsylvania

Nectar and host plants that bring butterflies to your garden — and give their caterpillars something to eat once they arrive. Every species here is genuinely native to Pennsylvania and the wider flora of the Mid-Atlantic and hardy through zones 5–7 — proven performers for Pennsylvania's humid continental climate across Appalachian ridge-and-valley & Piedmont, not a generic list. Local standouts include Wild Bergamot and Serviceberry. A real butterfly garden does two jobs: nectar for the adults and host leaves for the caterpillars. Flat-topped flowers make the best landing pads, and warm, sheltered, sunny spots out of the wind get the most visits. Tolerate a little leaf damage — those chewed leaves are the whole point, and a caterpillar today is a butterfly next month.
