When it comes to the variety of plants in the two parks, the only limiting factor is the high altitude; otherwise, the diversity of terrain, weather, and soils permits a fairly wide range of vegetation.
All said there are more than 1,100 native plant species found in Yellowstone, and 218 non native plant species. Wildflowers are abundant with more than 200 unique wildflower species found here.
Yellowstone has two distinct growing regions, above 10,000 feet and 7,000 feet to 10,000. Because of low temperatures and copious snow, Yellowstone trees are mostly hearty coniferous trees, like Lodgepole pines, Douglas firs and Blue Spruce. Lodgepole pines cover approximately 80% of the park. Some of the more common and interesting plants found Yellowstone’s various ecosystems are the Glacier Lily (found even at elevations over 7,500 feet!), Indian Paintbrush, the Wyoming State flower, as well as the Silky Phacelia and The Fairyslipper, two of the most beautiful and photogenic plants in the whole park. Though it may be tempting to investigate these plants of trail, remember the dangers associated with of-trail walking.
