Today, we will look at 5 different PINK wildflowers found in Oregon.


#1. Spreading Dogbane

  • Apocynum androsaemifolium

Also known as: Fly-trap Dogbane, Bitterroot

Pink wildflowers in Oregon

Growing Information:

  • USDA Hardiness Zone: 2-9
  • Life Cycle: Perennial
  • Approximate Mature Size: 24-60 in (61-152 cm) tall
  • Bloom Time: Summer
  • Sun Exposure: Full Sun to Full Shade

As you might have guessed from its name, Spreading Dogbane is a prolific grower, which is why you’ll find it widespread across both North America and Europe. It’s called “dogbane” because it is highly poisonous to dogs (and humans too).

Spreading Dogbane has small, pink bell-shaped flowers and a scent similar to lilac. Look for this pink wildflower in Oregon in the sandy soil of streambanks.


#2. Crown Vetch

  • Securigera varia

Also known as: Purple Crownvetch, Crownvetch

Oregon pink wildflowers

Growing Information:

  • USDA Hardiness Zone: 3-9
  • Life Cycle: Perennial
  • Approximate Mature Size: 12-72 in (30-183 cm) tall
  • Bloom Time: Summer to Fall
  • Sun Exposure: Full Sun to Partial Shade

Even though the large, pink clover-like blooms of Crown Vetch are beautiful, this plant is invasive in North America. Native to Europe, Asia, and Africa, Crown Vetch was introduced locally to be used as a groundcover in controlling soil erosion.

This pink wildflower grows in Oregon on sunny, sandy banks where it can push out less hardy plants.

If you plant Crown Vetch on your property, choose an isolated location far away from flower gardens. Don’t forget to control its growth so it doesn’t spread to other areas and invade native species and ecosystems.


#3. Wild Mint

  • Mentha arvensis

Types of pink wildflowers in Oregon

Growing Information:

  • USDA Hardiness Zone: 4-8
  • Life Cycle: Perennial
  • Approximate Mature Size: 3.9-39 in (10-99 cm) tall
  • Bloom Time: Late Spring to Early Summer
  • Sun Exposure: Full Sun to Light Shade

Wild Mint is a native wildflower with dense clusters of lavender, pink, or white bell-shaped flowers. Like other species of mint, the fragrance is most potent when the leaves are damaged.

Look for this pink wildflower in Oregon in wetlands with partial sunlight. It grows best on stream and river banks.


#4. Fireweed

  • Chamerion angustifolium

Also known as: Willow Herb

Pink wildflowers in Oregon

Growing Information:

  • USDA Hardiness Zone: 2-8
  • Life Cycle: Annual or Perennial
  • Approximate Mature Size: 18-120 in (46-305 cm) tall
  • Bloom Time: Late Spring and Summer
  • Sun Exposure: Full Sun to Partial Shade

True to its name, Fireweed is a resilient plant that will be the first to grow in clearings recently devastated by forest fires. In fact, Fireweed was seen growing throughout Washington State one year after Mount St. Helens erupted in 1980.

To find Fireweed, look for striking spikes of purplish-pink flowers covering a landscape. Hummingbirds, moths, and butterflies like to feed on this pink wildflower in Oregon.


#5. Deptford Pink

  • Dianthus armeria

Also known as: Grass Pink

Growing Information:

  • USDA Hardiness Zone: 3-8a
  • Life Cycle: Annual or Biennial
  • Approximate Mature Size: 12-30 in (30-76 cm) tall
  • Bloom Time: Spring to Fall
  • Sun Exposure: Full Sun to Partial Shade

The blooms of the Deptford Pink may be tiny, but they make up for their small size with their gorgeous coloring. A closer look at the petals will reveal an intricately dotted pattern of pink, white, and purple.

Deptford Pink is native to Europe, but this pink wildflower is a naturalized species in Oregon. It grows so well that it can take over roadsides, ditches, and fields.

Although the nectar is attractive to butterflies, skippers, and bees, Deptford Pink is a self-pollinating plant that doesn’t rely much on these insects.
