Here are 10 different WHITE wildflowers found in Montana!


#1. Wild Strawberry

  • Fragaria vesca

Also known as: Common Strawberry, Mountain Strawberry, Thick Leaved Wild Strawberry, Virginia Strawberry, Scarlet Strawberry

White wildflowers in Montana

Growing Information

  • USDA Hardiness Zone: 4-9
  • Life Cycle: Perennial
  • Approximate Mature Size: 4-7 in (10-18 cm) tall
  • Bloom Time: Spring to Fall
  • Sun Exposure: Partial Shade to Full Sun

The commercial strawberries we enjoy today were hybridized from Wild Strawberry, a white wildflower that grows natively in Montana. You can find this plant in disturbed habitats, meadows, river shores, woodlands, and even roadsides.

White, five-petalled flowers carpet the ground in spring where Wild Strawberries grow. The fruit of Wild Strawberries is much smaller than the ones we cultivate in gardens, but they are just as nutritious and tasty.

Birds and mammals also enjoy eating the tart fruits of the Wild Strawberry. In addition, the flower blooms attract bees, butterflies, and insect pollinators. In a garden setting, you can use this plant as a ground cover or for erosion control.


#2. English Plantain

  • Plantago lanceolata

Also known as: Ribwort Plantain, Lanceleaf Indianwheat, Ribgrass

Montana white wildflowers

Growing Information

  • USDA Hardiness Zone: 5-9a
  • Life Cycle: Perennial
  • Approximate Mature Size: 4-20 in (10-51 cm) tall
  • Bloom Time: Spring to Fall
  • Sun Exposure: Full Sun

The English Plantain is an introduced white wildflower in Montana, originally native to Europe and Asia.

It’s one of the most recognizable lawn weeds with its long, hairy, flowering spikes. These spikes contain small and inconspicuous white flowers.

You can spot English Plantain growing in disturbed habitats, dry meadows, grazing pastures, and roadsides. Its flowers are pollinated by flies and beetles, while songbirds eat their seeds.

Interestingly, English Plantain can adapt to different conditions depending on how humans try to eradicate it! For example, this plant naturally grows in tall stalks, but if the area where it grows is frequently mowed, it will grow low to the ground to avoid being cut.


#3. Hoary Alyssum

  • Berteroa incana

Also known as: False Hoary Madwort, Hoary Berteroa, Hoary Alison

Types of white wildflowers in Montana

Growing Information

  • USDA Hardiness Zone: 3b-7
  • Life Cycle: Biennial
  • Approximate Mature Size: 12-24 in (30-61 cm) tall
  • Bloom Time: Midsummer
  • Sun Exposure: Partial Shade to Full Sun

Hoary Alyssum is an invasive weed that you might find growing in pastures, riverbanks, roadsides, and lawns. Not only does it compete with native plants, but it can also be fatal to horses that eat it.

To identify this white wildflower in Montana, look for small white flowers on branching stems.

Each petal is deeply notched, so it might look like there are eight petals instead of four on every flower. The green leaves are covered with gray hairs.

Although bees, wasps, and other insects will eat Hoary Alyssum pollen, you’re better off killing this weed before it takes over your property. It can survive cold winters and hot summers. In addition, it thrives in poor soils and spreads prolifically, making it incredibly difficult to eradicate.


#4. White Clover

  • Trifolium repens

Also known as: Dutch Clover, Shamrock, Honeysuckle Grass

White wildflowers in Montana

Growing Information

  • USDA Hardiness Zone: 3-10a
  • Life Cycle: Perennial
  • Approximate Mature Size: 4-6 in (10-15 cm) tall
  • Bloom Time: Spring to Fall
  • Sun Exposure: Partial Shade to Full Sun

White Clover is native to Europe and Asia, but this white wildflower is considered a naturalized species in Montana. It grows so well that it can take over lawns, roadsides, pastures, and waste areas. Fortunately, however, White Clover doesn’t usually compete with native vegetation!

From spring to fall, White Clover blooms with an abundance of creamy white, rounded flowers. You might be familiar with its green leaves, which typically have three leaflets. But if you find one with four, you can consider yourself lucky! 🙂

Interestingly, all parts of the White Clover are edible. You can use the dried flowers to make tea or the young leaves in a salad. You can also grind the flowers and seed pods to be sprinkled as a seasoning on cooked food. It has a subtle vanilla-like flavor.


#5. Indian Hemp

  • Apocynum cannabinum

Also known as: Dogbane, Hemp Dogbane, Prairie Dogbane, Amy Root, Rheumatism Root, Wild Cotton

Growing Information

  • USDA Hardiness Zone: 3b-11
  • Life Cycle: Perennial
  • Approximate Mature Size: 24-60 in (61-152 cm) tall
  • Bloom Time: Spring to Summer
  • Sun Exposure: Partial Shade to Full Sun

Despite being native to North America, this white wildflower is considered an aggressive weed in Montana.

You’ll likely find it in dry, rocky woods, meadows, and prairies. Unfortunately, it also thrives on farms where it’s known to reduce the yield of corn, soybeans, and other crops.

In addition to its invasive nature, all parts of Indian Hemp are highly toxic to humans, dogs, and livestock. Avoid touching the milky sap, which can cause blisters on your skin. Its stiff, reddish stems and bushy lance-shaped leaves will help you identify this plant.

The small white flowers are rich with nectar, so don’t be surprised to see lots of butterflies and moths where Indian Hemp grows.


#6. Yarrow

  • Achillea millefolium

Also known as: Bloodwort, Carpenter’s Weed, Devil’s Nettle

Growing Information

  • USDA Hardiness Zone: 3-9
  • Life Cycle: Perennial
  • Approximate Mature Size: 24-36 in (61-91 cm) tall
  • Bloom Time: Summer

Planting Yarrow in your garden will reward you with abundant flowers that grow in clusters. They have small feathery leaves that look like ferns, and their scent might remind you of chrysanthemums (mums).

Some Yarrow plants were introduced from Europe in colonial times. However, there are many native subspecies of this white wildflower in Montana. Together, they form colorful hybrids that will attract bees, wasps, beetles, moths, and butterflies to your garden.

Yarrow plants naturally occur in disturbed areas, grasslands, open forests, and roadsides. They can tolerate drought and survive in less than perfect conditions.

  • Life Cycle: Perennial
  • Approximate Mature Size: 24-36 in (61-91 cm) tall

  • Sun Exposure: Partial Shade to Full Sun

Catnip is a famous plant with a long history of medicinal and culinary uses. Of course, you might know of Catnip as a recreational stimulant for cats. As a member of the Mint family, it has aromatic leaves that can repel mosquitoes, cockroaches, and termites.

Catnip is native to Europe and Asia, but this white wildflower is naturalized in Montana.

You can find it growing on roadsides, streams, waste grounds, dry banks, and fields. The triangular, veiny leaves and the small white or purple spotted flowers will help you recognize this plant.

Bees, butterflies, wasps, flies, and many pollinators love the nectar-laden flowers of Catnip. In addition, you can expect goldfinches and other birds to eat the seeds in the fall. Catnip grows best in full sun and well-drained soils.

  • Life Cycle: Biennial or Perennial
  • Approximate Mature Size: 47-94 in (119-239 cm) tall
  • Bloom Time: Summer
  • Sun Exposure: Partial Shade to Full Sun

Cow Parsnip is a relative of the cultivated parsnip. However, this white wildflower in Montana is not something you should eat. Be exceeding careful when gardening near this plant! The sap released from its broken leaves can cause blisters on your skin that take months to heal.

Typical of members of the carrot family, Cow Parsnip’s flowers occur in small, white clusters called umbels. The stems are tall and hairy, while the leaves are very large and divided into three lobes. Look for this plant in meadows, streamsides, and moist areas.

Cow Parnsip’s blooms are irresistible for birds and butterflies. The roots are also an important food source for wild animals. Bears are especially fond of them, so be careful of growing this plant in your backyard.

  • Asclepias verticillata

Also known as: Eastern Whorled Milkweed, Horsetail Milkweed

Growing Information

  • USDA Hardiness Zone: 4-9a
  • Life Cycle: Perennial
  • Approximate Mature Size: 12-36 in (30-91 cm) tall
  • Bloom Time: Summer

Whorled Milkweed is a single-stemmed perennial wildflower with flat-topped clusters of 7-20 small flowers. The fragrant white blooms are common in dry prairies, open woods, fields, and roadsides.

If you find this native white wildflower in Montana, you’re likely to also see hummingbirds, bees, wasps, butterflies, flies, skippers, and beetles. In addition, it’s an especially important food source for Monarch butterflies and their caterpillars.

Although Whorled Milkweed spreads quickly through underground rhizomes, it’s not considered invasive, so it’s a perfect choice for your garden! It stands well against drought, easily self-seeds, and tolerates most soil types.


#10. Oxeye Daisy

  • USDA Hardiness Zone: 3-8a
  • Life Cycle: Perennial
  • Approximate Mature Size: 12-24 in (30-61 cm) tall
  • Bloom Time: Spring to Summer
