Spring has sprung across much of the country, and with the change in season comes an eruption of color as wildflowers burst into bloom from coast to coast.

From desert valleys to grassland prairies and alpine meadows to big city parks, you’ll find them in profusion — daisies, buttercups, sunflowers, verbena, poppies and paintbrush in all their glory.

Here are seven places that have been recognized by experts and ordinary wildflower watchers alike as the best flower fields in the nation.

North Cascades National Park, Washington

Visitors flock in large numbers each spring and summer to this sprawling half-million-acre park to catch the beautiful flower displays that can be found nearly everywhere in North Cascades. They appear across a wide range of habitats from wet hillside seeps and shady forest floors to dry east-side slopes and exposed alpine ridges.

Flowering times range from March in low-elevation forests and meadows to August in alpine zones. Varietals vary across the park but you can expect to see bountiful displays of fireweed, tiger lily, Indian plum, red-flowering currant, alpine aster, evergreen violet and more. www.nps.gov/noca.

Cedar Breaks National Monument, Utah

Cedar Breaks is a massive half-mile-deep natural amphitheater, stretching across three miles of rugged canyon country in southwestern Utah. The park sits at an elevation of 10,000 feet, so spring arrives late and wildflower season is short. But come late May to early June, the rim of the canyon bursts to life with aspen bluebells, kittentails, lupine and cushion phlox.

Peak season is mid-July, when a host of other wildflowers appear, most notably Colorado columbine, scarlet paintbrush, sunflowers and elkweed. It is celebrated at the monument with a two-week-long Wildflower Festival featuring guided hikes and photography classes. www.nps.gov/cebr/wildflowers.

Fort Pierre National Grassland, South Dakota

Composed of 116,000 acres of gently rolling hills and mixed-grass prairie in central South Dakota, this national recreation area teems with wildflowers native to the Great Plains prairies from late spring through summer. Among the flowers to be seen here: fleabane, blue daisy, purple coneflower, prairie clover, blue flax, bluebell, columbine and silver bladderpod. www.fs.fed.us/wildflowers/viewing.

There’s no more iconic area to spot a field of bluebonnets than the Texas Hill Country.

Hill Country, Texas

The Texas Hill Country is renowned worldwide for its annual wildflower display that blankets the fields and roadways across a vast swath of south central Texas. The star of the floral show is the Texas bluebonnet — the Texas State Flower — but there’s also a profusion of primrose, Indian paintbrush, winecup and Indian blanket.

Many visitors go first to the Lady Bird Johnson Wildflower Center in Austin to learn how the state’s wildflower craze began under the passionate guidance of the former First Lady. Also worth a visit is Wildseed Farms near Fredericksburg. At 200 acres, it’s the nation’s largest wildflower farm. Trial gardens are free and open to the public from March to October.

A popular half-day wildflower tour follows Texas State Highway 16 from Medina through Kerrville to Llano. For current blooming info, call the Texas Department of Transportation Wildflower Hotline, 800-452-9292.

Shenandoah National Park, Virginia

Straddling Virginia’s Blue Ridge Mountains — and the heavily traveled Skyline Drive that runs through it — this leafy national park is a safe haven for 862 species of wildflowers. The show usually gets underway in March with displays of liverwort, white bloodroot, purple trillium, wild geraniums, pink lady slippers and violets.

As summer begins, so does an amazing array of wildflowers, including columbines, oxe-eye daisies, goldenrods, asters and sunflowers. Visitors driving through the park can gain some excellent wildflower sightings right from the highway, especially during late summer, but the best viewing goes to those who venture off the Skyline Drive.

Look for blooms in lower-lying areas and along streams, including Rose River, South River, Hughes River and Mill Prong. Close by, in Washington, D.C., there’s the celebrated annual blooming of cherry blossoms along the Capitol’s Tidal Basin, predicted to occur this year sometime during the first week in April. www.nps.gov/shen/learn/nature/wildflowers.htm.

The Great Smoky Mountains are synonymous with wildflowers.

Great Smoky Mountains National Park, North Carolina/Tennessee

Stretching across a half-million acres of Tennessee and North Carolina, Great Smoky is a world-renowned preserve of wildflower diversity. More than 1,500 kinds of plants have been identified there — more than in any other national park. That’s why it’s been dubbed the “Wildflower National Park.”

It is most famous among flower fanciers for its glorious displays of mountain laurel, rhododendron and azalea. Here again, get off the Parkway and make time for a wildflower hike along one of the park’s many trails.

Time your stay to join the annual Spring Wildflower Pilgrimage, April 24-27, for professionally guided walks and naturalist lectures. www.nps.gov/grsm/learn/nature/wildflowers.htm.

Death Valley National Park, California

Death Valley has not received the early season rains needed for a “superbloom” like the park experienced in 2016, but there has been some rain (and snow!) of late, so prospects are improving for some action later this spring.

At lower elevations, look for desert gold, the fragile white gravel ghost, desert sunflowers, primrose, desert five-spot and several variations of phacelia. At higher elevations, including the volcanic hillsides north of Ashford Junction, you’ll likely see some brittlebush, Mohave aster, desert paintbrush, lupine, bear poppy and sage — most flowering into June and early July.

Two other spots in Southern California famous for their wildflower blooms include Antelope Valley’s California Poppy Reserve, and Anza-Borrego State Park. www.nps.gov/deva.
