Grand Canyon National Park contains 129 vegetation communities, and the composition and distribution of plant species is influenced by climate, geomorphology and geology.
Along the Colorado River and its perennial tributaries, a riparian community exists. Coyote willow, arrowweed, seep willow, western honey mesquite, catclaw acacia, and exotic tamarisk (saltcedar) are the predominant species. Hanging gardens, seeps and springs often contain rare plants such as the white-flowering redbud tree, stream orchid, and McDougall's flaveria.
Above the river corridor a desert scrub community, composed of North American desert flora, thrives. Typical warm desert species such as creosote bush, white bursage, brittle brush, catclaw acacia, ocotillo, mariola, western honey mesquite, four-wing saltbush, big sagebrush, blackbrush and rubber rabbitbrush grow in this zone.
Above the desert scrub and up to 6,200 feet is a pinyon pine, Utah and one seed juniper woodland. Within this woodland one can find big sagebrush, snakeweed, Mormon tea, Utah agave, banana and narrowleaf yucca, snakeweed, winterfat, Indian ricegrass, dropseed, and needlegrass.
A permit is required for collecting plants in the park.

President Theodore Roosevelt said of Grand Canyon, "Leave it as it is. The ages have been at work on it, and man can only mar it. What you can do is to keep it for your children, your children's children, and for all who come after you, as one of the great sights which every American should see."
