Montana is one of the states with meadows and prairie wildflowers. Some of the species adapted to cool climates and high elevations are specific to Montana.
Some of the wildflowers found here can be grown in gardens while others have a rich history going back to the times they were used in traditional health practices.
Both native and introduced species are found around the state. Here are some of the typical wildflowers of the state with their most common traits.
1. Common Yarrow
With a long season spreading from March to October, The Common Yarrow (Achillea millefolium) is a typical wildflower across various habitats in the state.
This species does well on disturbed land as well.
This species has multiple white flowers with a size of up to 8mm.
Its white flowers grow in groups, typically numbering 8 or fewer flowers.
Common Yarrow has a toxic effect on pets and wild animals in Montana. Vomiting and diarrhea are among the typical symptoms when animals eat them.
A higher toxicity risk is associated with cattle as cows transmit the toxins of the plant through milk.
Fireweed (Chamaenerion angustifolium) is a wildflower with an erect inflorescence. Purple-violet coloring is specific to its inflorescence which blooms on the bottom first.
This species has quick-establishing roots and it enjoys popularity across disturbed lands, mainly in those affected by fire.
Its deep roots spread quickly and help stabilize the soil. Even more, its roots can be the first to establish on fire-disturbed land.
Its capacity to grow even on some of the most difficult terrains is what may make the flower an unexpected sight on the state’s granite terrains.
3. Glacier Lily
Common spotted around the state and Missoula, Glacier Lily (Erythronium grandiflorum) is a species that grows and re-grows from bulbs.
Its globular yellow flowers often make this species resemble yellow tulips.
The mountainous regions across the state are its ideal habitats.
While it doesn’t grow at the highest elevation, Glacier Lily Grows in subalpine areas.
Clearings in woodlands, open sunny spaces next to woodlands, and sunny slopes are among its preferred habitats.
Glacier Lilies grow to an average size of 9-11 inches.
This plant is edible. Animals such as bears feed on their yellow flowers.
4. Common Beargrass
A type of perennial herb, Common Beargrass (Xerophyllum tenax) is a species tied to subalpine regions.
The leaves of the species grow on the base of the plant with white tiny flowers forming a globular shape on top.
This species isn’t food for bears as other animals such as deer prefer to feed on it.
A native species in Montana, Common Beargrass has now expanded its reach outside of state borders.
Common Beargrass is now expanded throughout the entire West Coast.
The high elevation and the presence of sufficient rainfall in the spring favor the spread of The Common Beargrass.
5. Sticky Geranium
A type of wild geranium, Sticky Geranium (Geranium viscosissimum) is native to Montana and the extended Northeast.
This is a species that grows into a short wildflower with blooming dark pink flowers.
Its season extends to October and depends on elevation.
Subalpine habitats are specific to Sticky Geranium, a species that grows at an altitude of up to 8.000 feet.
While the species may also be seen at a lower elevation, Sticky Geranium is most likely to be seen in gardens outside its subalpine areas.
Its fragrant colorful flowers attract moths and butterflies.
6. Arrowleaf Balsamroot
The Arrowleaf Balsamroot (Balsamorhiza sagittata) is native to Montana and to numerous other Western habitats, particularly at high elevations.
A preference for cold habitats is specific to this plant. A sunflower family member, this species has yellow florets, a combination of multiple small yellow flowers.
Like true sunflower, this species has pointy petals.
Arrowleaf Balsamroot, also known as Oregon Sunflower is a species an edible wildflower. Some reports say this wildflower was eaten by local natives for its nutritional value as its high in oil.
Arrowleaf Balsamroot was and still is boiled into a tea which boosts energy levels.
7. Great Blanketflower
The colorful Great Blanketflower (Gaillardia aristata) is another common species in subalpine areas found in Montana.
The species is also native to the entire West Coast up to British Colombia.
Orange and yellow colors are specific to their bright colors, which attract wildlife such as bees and butterflies.
This is a species that grows in full sun, preferably in prairies.
Great Blanketflowers rarely reach their maximum height of just over 20 inches as they need plenty of moisture.
They can be grown at home in enriched soil containers and remain in bloom from spring to early summer.
Saskatoon (Amelanchier alnifolia) is a species native to Canada and Montana that bear fruit.
The fruits of this species taste similarly to berries and are rich in nutrients such as riboflavin.
These fruits are ripe at the beginning of the summer as opposed to earlier in the season West of Montana.
Known for its multiple blooming white flowers, Saskatoon also has edible leaves which wild animals like.
Deer are among the species that feed on the wildflower.
Saskatoon is a species that grows considerably. It can reach a height of up to 30 feet within years.
Its leaves and fruits can be used to make different drinks, including flavored craft beer.
An atypical appearance is specific to the Fiary-Slipper (Calypso bulbosa). This wildflower is part of the orchid family, bearing resemblance to other orchids in its flowers.
Only one flower per stem is specific to this species. Its flowers are pink-violet and may come with white margins.
Fairy-Slipper flowers attract pollinators but are a rare sight as they are only found in high-elevation woodlands.
Pine woodlands are among their ideal habitats. This species never grows in an exposed area as it requires shelter.
A single leaf grows on this type of wildflower.
10. Common Harebell
Common Harebell (Campanula rotundifolia) is a species found across the state and outside Montana in many temperate climates.
It grows to a height between 7 and 14 inches and it blooms bell-shaped flowers. Its flowers are blue, purple, or pink.
