Below are selected plants found in ecosystems of the park and preserve, beginning with alpine tundra.
These alpine phlox were on Marble Mountain at approximately 13,000' (3963m). Access Marble Mountain via Music Pass in Great Sand Dunes National Preserve.

Alpine phlox look somewhat like "flocks" of sheep on a grassy hillside. They grow in a mossy mat, and are common on alpine tundra.
NPS/Patrick Myers
Dwarf clover are tiny magenta clover that grow out of a soft mat, hugging the ground closely to stay close to the earth's warmth on chilly alpine tundra.
NPS/Patrick Myers
Alpine forget-me-nots are dwarfed, brilliant blue versions of their larger low-elevation cousins. They grow in small bunches on alpine tundra.
When hiking on tundra, please step carefully to avoid crushing small alpine plants. Some plants take decades to reach maturity in the slow growing conditions.
NPS/Patrick Myers
Fairy primrose, like most alpine tundra plants, are small, fragile, and close to the ground to survive arctic-like conditions. These magenta-lavender flowers have daisy-like petals.
Alpine avens are one of the most common tundra plants, resembling small yellow buttercups.
Bristlecone pines receive heavy snow and rain most years.
NPS/Patrick Myers
Bristlecone pines (left) grow best along high, wet ridges in the Sangre de Cristo Mountains. Bristlecones and limber pines are the two primary conifers in krummholz at treeline in the Rocky Mountains of Colorado.
Tall subalpine conifers and wildflowers contrast the arid habitats of the valley floor below.
NPS/Patrick Myers
Subalpine forests receive heavy precipitation each year in rain and snow, allowing for tall subalpine firs and pines. Blue penstemon are common along trails in Great Sand Dunes National Preserve.
NPS/Patrick Myers
Subalpine flowers grow in high, wet meadows surrounded by forest. At left, red Indian paintbrush, white lousewort, and blue-purple penstemon seem to be patriotic with colors of the United States flag. Small aspen daisies at lower left, and yellow western paintbrush at upper left are also part of this natural garden photographed high in the Sangre de Cristo Mountains.
NPS/Great Sand Dunes NPP
Elephantella or "Little Pink Elephants" are an aptly named magenta stalk of little elephant-head-shaped flowers, blooming in mid-summer in subalpine meadows.
These flowers are already fully formed as the snowfield shrinks in late June.
NPS/Patrick Myers
Snow buttercups begin growing under the snow, as sunlight and water begin filtering through in spring. When the snowfield disappears, the flowers are ready to open up for a short subalpine summer season.
The montane zone is along the foothills of the Sangre de Cristo Mountains. This autumn view is from the Montville Trail.
NPS/Patrick Myers
Douglas fir and aspen trees can live in either subalpine or montane forests, as long as there is plenty of moisture. In drier montane woodlands, they are only found near drainages where there is sufficient groundwater.
Some junipers along the foothills have been dated at over 700 years old.
NPS/Patrick Myers
Rocky Mountain juniper trees mix with pinyon trees along the montane foothills of the Sangre de Cristo Mountains.
NPS/Phyllis Pineda Bovin
Pinyon trees are the predominant tree of drier montane woodlands along the foothills of the Sangre de Cristo Mountains. They are mixed with Rocky Mountain junipers (above). Pinyon nuts are enjoyed by animals and people.
Three-leaf sumac is also known as "lemonade bush" because of its lemony red berries.
NPS/Patrick Myers
Three-leaf sumac is a montane shrub that can turn brilliant shades of crimson or gold in fall. In summer, it produces sticky red berries that taste like a sour lemon drop; these have been used by pioneers and Indian tribes to make lemonade.
NPS/Phyllis Pineda Bovin
Smith's draba is a small, magenta-purple flower endemic to the Sangre de Cristo and San Juan Mountains surrounding the San Luis Valley of southern Colorado. This rare plant is not often seen. Look for it in rocky areas of the montane foothills.
NPS/Carol Sperling
Scurfpea is the most common leafy plant that grows on the dunefield. With tiny purple blossoms in spring, scurfpea attracts pollinating insects who seek its flowers, and other insects who simply seek its shade.
NPS/Great Sand Dunes NPP
Indian ricegrass (left) and blowout grass are the most common grasses that grow on the dunefield itself. Containing small black rice seeds, ricegrass is an important food source for Ord's kangaroo rats.
As the wind moves blowout grass, it may make unusual circles in the sand.
NPS/Great Sand Dunes NPP
Blowout grass looks similar to Indian ricegrass (above), but lacks the characteristic black rice seeds. Along with ricegrass, it is a common grass found in the dunefield.
These sunflowers bloomed in August 2006 after heavy rains.
NPS/Patrick Myers
Prairie sunflowers can number in the millions during wet summers in grasslands surrounding the dunes, and also grow in patches on the dunes.
NPS/Patrick Myers
Rocky Mountain beeplants generate a lot of questions from visitors in mid-summer. They resemble some kind of exotic tropical flower, and like tropical flowers need abundant moisture. They grow profusely in wet summers or in wet areas of grasslands or montane woodlands.
NPS/Patrick Myers
Rubber rabbitbrush is the most common shrub of the park's grasslands. In September, it flowers out to match the golden aspens on the mountains.
NPS/Patrick Myers
Speargrass, also known as needle-and-thread grass, is popular with children who throw the little "spears" at others' clothing. The spears stick not only to clothes, but also occasionally to animals and passersby, transporting the plant's seeds to other locations in the grasslands.
NPS/Patrick Myers
Small-flowered sand verbena has a large, pinkish seedpod that is often mistaken for a flower. The flowers on this plant are actually tiny, white and trumpet-shaped. Look for these in summer months in the park's grasslands.
NPS/Patrick Myers
Narrowleaf yuccas bloom in early summer with creamy white blossom that attract deer and elk. Common in grasslands, yuccas are also found on drier south-facing slopes in montane woodlands.
NPS/Patrick Myers
Prickly pear cactus are the most common of the cactus varieties in the park. They occur in drier parts of grasslands, and on dry south-facing slopes in montane woodlands.
NPS/Patrick Myers
Visitors are sometimes puzzled by ring muhly, a grass that grows in a circle in drier parts of the park's grasslands. This grass grows outward, releasing a chemical inside the circle that prevents other grass from growing there. In this way, a "bucket" is formed that captures rainfall in this desert climate.
Inland saltgrass can survive wide variances between water saturation in early summer and dry, salty conditions in late summer. This is the primary type of grass around sabkha wetlands in the park.
NPS/Patrick Myers
Slender spiderflower is a somewhat rare plant, growing only in alkali wetlands in the western United States. It is related to Rocky Mountain beeplant (above), but prefers even wetter habitats.
NPS/Patrick Myers
Wild iris color wet meadows in and around wetlands in May and June each year.
NPS/Great Sand Dunes NPP
White water buttercup blooms mid-summer in wetlands west of the main dunefield. Chorus frogs and toads use the floating leaves as a resting or hiding place while in the water.
