Lewis and Clark

A Route to the Pacific

Today, in 1806, Lewis and Clark returned to St. Louis after spending over two years exploring the headwaters of the Missouri River in an effort to find a route to the Pacific. 

They returned with their journals and with plant specimens. Here's just a handful of the plants they discovered (I picked the ones you might be the most familiar with):
Snow-on-the-mountain (Euphorbia marginata)
Creeping juniper (Juniperus horizontalis)
False indigo (Amorpha fruticosa)
Needle-and-thread grass also called porcupine grass (Hesperostipa comata)
Purple coneflower (Echinacea angustifolia)
Rough gayfeather also called large button snakeroot (Liatris aspera)
Wild four-o'clock (Mirabilis nyctaginea)
Wild rice (Zizania palustris)
Wild rose (Rosa arkansana)
