Plants of Yellowstone National Park
The 15 plants you can find at Yellowstone National Park, like the American pasqueflower — sizes, diets, and whether you should worry.
-
Plant American pasqueflower
Pulsatilla patens ssp. multifida
A furry, purple-blue prairie flower that beats the grass out of the ground each spring, blooming before almost anything else is green.
-
Plant Big sagebrush
Artemisia tridentata
The silver-leaved, sharp-smelling evergreen shrub of the high desert West, and the main food of the greater sage-grouse nearly all year.
-
Plant Black huckleberry
Vaccinium membranaceum
The dark purple berry that feeds Glacier's bears and half the pancakes in Montana, growing on open and burned slopes all over the park.
-
Plant Colorado blue columbine
Aquilegia coerulea
Colorado's blue-and-white state flower, its long spurs full of nectar that only a hawkmoth's tongue can reach.
-
Plant Douglas-fir
Pseudotsuga menziesii
One of the tallest trees on Earth, not actually a true fir, whose cones carry little three-pointed flaps a Native story calls the tails and legs of hiding mice.
-
Plant Engelmann spruce
Picea engelmannii
A high-elevation spruce with scaly bark and sharp, squarish needles, whose Colorado stands have lost more than a million acres to a beetle since 1996.
-
Plant Fireweed
Chamerion angustifolium
A tall pink-purple wildflower that is often the first color to return to a burned mountainside.
-
Plant Glacier lily
Erythronium grandiflorum
A nodding yellow spring flower whose bulb is such important grizzly bear food that the bear's digging can grow bigger flowers the following year.
-
Plant Indian paintbrush
Castilleja miniata
A scarlet mountain wildflower that steals water and food from its neighbors' roots, and whose bright color comes from leaves, not petals.
-
Plant Lodgepole pine
Pinus contorta var. latifolia
The thin-barked pine covering 80% of Yellowstone's forest, some of whose cones only open in the heat of a fire.
-
Plant Quaking aspen
Populus tremuloides
A white-barked mountain tree whose flat-stemmed leaves shiver in the lightest breeze, turning whole hillsides gold each fall.
-
Plant Subalpine fir
Abies lasiocarpa
A narrow, spire-shaped high-mountain fir with smooth gray bark and flat, soft needles, moving in wherever fire has stayed away long enough.
-
Plant Western wheatgrass
Pascopyrum smithii
A blue-green prairie grass whose underground rhizomes weave a tough sod — the official state grass of North and South Dakota.
-
Plant Whitebark pine
Pinus albicaulis
The twisted pine at Glacier's treeline that feeds grizzlies and Clark's nutcrackers, holds the snowpack in place, and is dying faster than it grows.
-
Plant Yellowstone sand verbena
Abronia ammophila
A white-flowered relative of desert sand verbenas found nowhere on Earth except a few beaches on Yellowstone Lake.
