Don’t let that pretty foliage fool you. This case in Botany Hall is full of local plant species that are poisonous or irritating to humans.
Of the nearly 3,500 plant species in Pennsylvania, about 100 can cause rashes, skin irritation, or even death.
Plants like poison ivy, primrose, common ragweed and other nefarious plants found in and around Pittsburgh are included in the case. Take a closer look at Carnegie Museum of Natural History!
