July Wildflower Guide

July in Grand Teton National Park is a time when the landscape truly bursts into a vibrant tapestry of color. At Wildlife Expeditions of Teton Science Schools, we’re not just passionate about wildlife; we’re also captivated by the dazzling display of wildflowers that blanket the meadows, forests, and alpine slopes this time of year. 

 

July is typically peak wildflower season in many areas of the park, offering incredible photographic opportunities and a chance to immerse yourself in the beauty of the Greater Yellowstone Ecosystem. Whether you’re hiking up Cascade Canyon or enjoying the shores around Jenny Lake, these floral gems are sure to catch your eye and capture your heart. 

 

Based on our years of exploring these incredible landscapes and drawing inspiration from resources like the National Park Service and Wildflower Search, we are proud to share a glimpse into what you may encounter during your July adventures. So here is our guide on where to look and what you may see:  

Valley Floor Meadows (Antelope Flats Road, Oxbow Bend, Mormon Row): These lower elevation areas often see an abundance of early to mid-season bloomers. Look for:

Bright red stalks of Indian Paintbrush
  • Indian Paintbrush (Castilleja coccinea) Its vibrant red, orange, and yellow bracts are iconic. You’ll likely see several different species.
Meadow of Wildflowers in Scenic Mountain Canyon – Springtime bloom of colorful, vibrant wildflowers.
  • Lupine (Lupinus perennis): Tall spires of purple, blue, and sometimes white flowers add a splash of color to the meadows.
Monkey flowers grow in sunlight and semi-shade (light woodland) and require moist to wet soil. As illustrated here, they can grow in water. The flowers have blobs of red along the nectar line, leading into the corolla, similar to the smaller (and more spectacular) blood drop emlets. The foliage is edible, raw or cooked, and has been used to add a slightly bitter flavour to salads. In this way, the leaves have been used as a substitute for lettuce. (The photographer tested none of this.) Mimulus guttatus is a native of western North America, where it is a complex and variable species. In Britain and Europe, it is widely naturalised but does not show the same variability.
  • Cinquefoil (Potentilla): Yellow, five-petaled flowers are common.
Achillea millefolium, common yarrow, white flowers with green leaves.
  • Yarrow (Achillea millefolium): Flat-topped clusters of white or pink flowers are easily recognizable.
Small purple asters, wildflowers, background, deep in the field.
  • Various Asters and Fleabanes (Asteraceae family): Keep an eye out for purple, pink, and white daisy-like flowers starting to appear.

Lakeshore Trails (Jenny Lake, String Lake, Leigh Lake): The edges of these pristine lakes offer a mix of sun and moisture, supporting a variety of species:

Fireweed blooms on the summer plateau.
  • Fireweed (Chamerion angustifolium): Tall stalks adorned with magenta-pink flowers create stunning displays, especially in areas that have experienced disturbance.
Monkey flowers grow in sunlight and semi-shade (light woodland) and require moist to wet soil. As illustrated here, they can grow in water. The flowers have blobs of red along the nectar line, leading into the corolla, similar to the smaller (and more spectacular) blood drop emlets. The foliage is edible, raw or cooked, and has been used to add a slightly bitter flavour to salads. In this way, the leaves have been used as a substitute for lettuce. (The photographer tested none of this.) Mimulus guttatus is a native of western North America, where it is a complex and variable species. In Britain and Europe, it is widely naturalised but does not show the same variability.
  • Monkeyflower (Mimulus ringens): Look for their distinctive snapdragon-like flowers in various shades of yellow and orange, often in damp areas.

  • Gentians (Gentiana): Deeper blues and purples will start to appear later in July in some areas.
Blue wildflower, blue mist penstemon, penstemon virens, growing on the side of Pike’s Peak Mountain in Colorado in the Western United States of America.
  • Small-flowered Penstemon (Penstemon procerus): Clusters of small, tubular blue to purple flowers.

 

Mid-Elevation Hikes (Taggart Lake & Bradley Lake Trail, Hidden Falls & Inspiration Point Trail): As you gain a bit of elevation, you’ll encounter a new suite of wildflowers:

A bunch of wild Colorado Blue Columbine blooming at the side of Isabelle Glacier Trail in Indian Peaks Wilderness, Colorado, USA.
  • Columbine (Aquilegia): Delicate spurred flowers in shades of purple, yellow, and red are a treat to discover in shadier spots.
Wild roses in the summer sun.
  • Wild Rose (Rose acicularis): Pink blossoms with a sweet fragrance.
Phlox subulata flowers in a rock garden.
  • Various Phlox species (Phlox): Clusters of pink, purple, or white flowers.

 

Higher Elevation/Alpine Zones (Cascade Canyon, most Teton Crest Trails): For those venturing into the alpine zone, be prepared for a different, often smaller, but equally beautiful array:

Alpine forget-me-not, a plant with blue flowers that may be found in alpine zones in the Colorado Rocky Mountains.
  • Alpine Forget-Me-Not (Myosotis asiatica): Tiny, brilliant blue flowers that thrive in harsh conditions.
Silene acaulis is a small mountain-dwelling wildflower that is common all over the high Arctic and tundra in the higher mountains.
  • Moss Campion (Silene acaulis): Forming dense cushions of pink or purple flowers close to the ground.
Bird’s-eye primrose (Primula farinosa) on the bank of the ditch. Light purple flowers of the bird’s-eye primrose, Primula farinosa, bloom in nature during springtime
  • Parry’s Primrose (Primula parryi): Vibrant magenta flowers are often found near melting snowfields.

  • Sky Pilot (Polemonium viscosum): Clusters of bright blue flowers that seem to reach for the sky.

 

Our tips for Wildflower Viewing:

  • Time of Day: Early mornings and late afternoons often provide the best lighting for photography, making vibrant colors pop.
  • Respect the Environment: Please stay on trails to avoid trampling delicate wildflowers and their habitats. Remember the Leave No Trace principles.
  • Bring a Field Guide or App: Resources like the NPS Wildflower Guide and the Wildflower Search database, as well as plant identifier apps like Picture This, can help you identify what you’re seeing.
  • Be Bear Aware: July is an active time for wildlife. Carry bear spray and know how to use it. Make noise while hiking.
  • Elevation Matters: Wildflower blooms progress with elevation. Lower elevations will bloom earlier, while higher elevations will peak later in the season.
  • Weather Dependent: Bloom times can vary slightly depending on snowmelt and weather patterns.

At Wildlife Expeditions, our guides are knowledgeable about the local flora and fauna and can help you spot and identify the beautiful wildflowers you encounter on your tour. We believe that appreciating the intricate details of the natural world, like the delicate beauty of a wildflower, enhances our connection to this incredible place. 

So, lace up your boots, pack your camera, and join us in celebrating the July wildflower bloom in the Greater Yellowstone Ecosystem. We look forward to sharing the wonders of Wyoming’s natural beauty with you. Book your tour here.
