Common Wildflowers In Idaho
Idaho has over 3,000 native plant species. That’s a lot to remember. But you don’t need to know them all. Start with these 15 common wildflowers. They grow in many parts of the state, from low deserts to high mountains.
Arrowleaf Balsamroot
This is one of the most iconic flowers in Idaho. You’ll see it covering hillsides in bright yellow during spring. It grows in dry, open areas. The leaves look like arrowheads, which gives it the name.
- Blooms: April to June
- Height: 1 to 2 feet

Indian Paintbrush
This flower adds red, orange, or pink to the landscape. It’s not a true paintbrush, but it looks like one. The color comes from modified leaves called bracts. The actual flowers are small and green.
You’ll find it in meadows and along roadsides. It grows best in well-drained soil. Indian paintbrush is a hemiparasite, meaning it gets some nutrients from other plants.
Lupine
Lupine stands tall with spikes of blue, purple, or pink flowers. It’s common in mountain meadows and along streams. The leaves are palmate, shaped like a hand with fingers spread out.
Lupine fixes nitrogen in the soil, which helps other plants grow. But be careful: it’s toxic to livestock and humans if eaten in large amounts.
Blue Flax
This delicate flower has five petals that are sky blue. It opens in the morning and falls off by afternoon. Each flower lasts only one day, but new ones appear daily.
Blue flax grows in dry, rocky soil. It’s often used in wildflower seed mixes. You’ll see it along highways and in open fields.
Yarrow
Yarrow has flat clusters of small white or pink flowers. The leaves are feathery and fern-like. It’s a tough plant that grows in many conditions.
Native Americans used yarrow for medicine. It can stop bleeding and reduce fever. Today, it’s a common sight in meadows and disturbed areas.
Penstemon
Also called beardtongue, penstemon has tubular flowers in shades of blue, purple, red, or pink. The flowers are shaped like little trumpets. They attract hummingbirds and bees.
There are over 30 species of penstemon in Idaho. They grow in dry, sunny places. Some species are found only in specific mountain ranges.
Wild Rose
Wild roses have five petals and a sweet scent. They range from pale pink to deep rose. The hips (fruits) are red and rich in vitamin C.
You’ll find wild roses along streams and in moist meadows. They form thickets that provide cover for birds and small mammals. The petals are edible and can be used in teas.
Fireweed
Fireweed is tall with spikes of magenta flowers. It’s one of the first plants to grow after a fire. The seeds spread easily in the wind.
This flower grows in disturbed areas, clearings, and along roads. The young shoots are edible and taste like asparagus. Fireweed honey is a local specialty.
Mule’s Ear
Mule’s ear looks like a sunflower but with larger leaves. The leaves are long and fuzzy, resembling a mule’s ear. The flowers are bright yellow with many petals.
It grows in dry, open areas like sagebrush plains. It blooms from May to July. The plant can survive drought by storing water in its roots.
Glacier Lily
This is one of the first flowers to bloom in spring. It has yellow, nodding flowers with petals that curve backward. It grows in moist, shady areas near melting snow.
Glacier lilies are common in the Sawtooth and Bitterroot mountains. They often form large colonies. The bulbs were eaten by Native Americans and early settlers.
Shooting Star
Shooting star has unique flowers that point downward. The petals are swept back, giving it a shooting star look. Colors range from white to pink to purple.
It grows in wet meadows and along streams. It blooms in late spring. The flowers are pollinated by bumblebees, which land on the petals to reach the nectar.
Wild Iris
Wild iris has showy blue or purple flowers with three petals and three sepals. It grows in wet areas like marshes and stream banks. The leaves are sword-shaped.
There are several species in Idaho, including the Rocky Mountain iris. The roots contain compounds that can cause skin irritation. Handle with care.
Bitterroot
Bitterroot is Idaho’s state flower. It has pink to white petals that open in the sun. The leaves are fleshy and succulent. It grows in dry, gravelly soil.
The roots were a staple food for Native Americans. They were dried and stored for winter. The name comes from the bitter taste of the raw root.
Silky Lupine
This is a smaller lupine with silky hairs on the leaves and stems. The flowers are blue or purple. It grows in sandy soil and open forests.
Silky lupine is common in the northern part of the state. It blooms from May to July. Like other lupines, it fixes nitrogen in the soil.
