The United States is home to some of the most biodiverse landscapes on the planet, many of which are protected within its vast network of national parks. From misty mountain ranges to sun-scorched deserts, these unique ecosystems are the last remaining sanctuaries for some of the world’s rarest and most resilient plants.
In certain parks, you’ll find plants that exist nowhere else on Earth — not even in neighboring regions. Think of the Giant Sequoia, which towers exclusively in California’s Sierra Nevada, or the striking Saguaro Cactus, found only in the Sonoran Desert around Arizona’s Saguaro National Park. These rare species not only define the identity of the parks they inhabit, but they also tell stories of ancient climates, evolution, and adaptation.

Whether you’re a traveler, a nature lover, or a botany enthusiast, these plants are well worth the pilgrimage.
