They look harmless in the garden — until they escape. Uprooted: Plants Out of Place, a long-term exhibition at Carnegie Museum of Natural History, tells the surprising story of invasive plants: how kudzu, Japanese knotweed, garlic mustard and other botanical travelers crossed oceans (often in suitcases and seed catalogs) and rewrote Pennsylvania’s forests.
The exhibition mixes museum science with backyard relevance — because the front line of this story is your own garden. Displays trace the museum’s botany research, show how scientists track plant invaders, and share what gardeners can plant instead: native species that feed local birds, bees and butterflies.
Uprooted is at Carnegie Museum of Natural History, 4400 Forbes Avenue in Oakland, and runs for several years as part of the museum’s long-term galleries — plenty of time to see it, and to rethink your flowerbeds. Included with admission.
