Today, we will look at 4 ORANGE wildflowers you can find in Idaho.

 


#1. Orange Hawkweed

  • Hieracium aurantiacum (synonymous with Pilosella aurantiaca)

Also known as: Orange Hawkbit, Orange Aster, Devil’s Paintbrush, King Devil Hawkweed, Devil’s Weed, Tawny Hawkweed, Red Daisy Flameweed, Grim-the-collier, Fox and Cubs

Orange wildflowers in Idaho

Growing Information

  • USDA Hardiness Zone: 5-10
  • Life Cycle: Perennial
  • Approximate Mature Size: 10-24 in (25-61 cm) tall
  • Bloom Time: Summer to Early Fall
  • Sun Exposure: Full Sun or Partial Shade

 

Orange Hawkweed is a favorite of many gardeners for its coppery, orange-red to yellow flowers with black tips that attract many pollinators. Did you know the ancient Greeks believed that the milky sap of hawkweeds gave hawks their sharp eyesight?

 

This orange wildflower was introduced to Idaho in the 1800s. Interestingly, research in 2009 revealed that most Orange Hawkweed populations collected in North America are genetic clones of one another. This reveals that they all came from the same original plant!

 

Beware! Orange Hawkweed grows aggressively fast!

 


#2. Spotted Touch-Me-Not

  • Impatiens capensis (formerly known as Impatiens biflora)

Also known as: Orange Balsam, Orange Jewelweed, Jewelweed, Common Jewelweed, Spotted Jewelweed, Snapweed, Spotted Snap Weed, Silver Leaf, and Silver-cap

Idaho orange wildflowers

Growing Information

  • USDA Hardiness Zone: 2-11
  • Life Cycle: Annual
  • Approximate Mature Size: 24-60 in (61-152 cm) tall
  • Bloom Time: Summer
  • Sun Exposure: Shade to Partial Sun

 

Spotted Touch-Me-Not is famous for its yellowish-orange flowers with brown spots. As the name suggests, its seed pods will explode if you touch them!

 

The Spotted Touch-Me-Not comprises approximately one-tenth of the Ruby-throated Hummingbird’s diet. The long tubular flowers of the Spotted Touch-Me-Not are especially attractive to hummingbirds who use their slender beaks to collect the nectar.

 

Plant this orange wildflower in Idaho if you want to attract birds!

 

In addition to hummingbirds feasting on the nectar, the seeds are eaten by birds such as the Ruffed Grouse and the Ring-necked Pheasant.

 


#3. Tropical Milkweed

  • Asclepias curassavica

Also known as: Scarlet Milkweed, Bloodflower, Cotton Bush, Sunset Flower, Swallow Wort, Silkweed, Indian Root, Curassavian, Cancerillo (Spanish); Bloodflower, and Mexican Milkweed

Growing Information

  • USDA Hardiness Zone: 8b-11
  • Life Cycle: Perennial
  • Approximate Mature Size: 24-48 in (61-122 cm) tall
  • Bloom Time: Late Spring to Early Fall
  • Sun Exposure: Full Sun or Partial Shade

 

Tropical milkweed’s distinctive blossom has five orangish-red petals that bed backward, with a yellow star-shaped crown. Although it isn’t a native orange wildflower, it has become invasive across much of the country.

 

Unfortunately, Tropical Milkweed planted in Idaho may do more harm than good.

 

It carries a parasite that affects Monarch Butterflies called Ophryocystis elektroscirrha, or OE, which can cause defects in the wings of Monarchs. Since it doesn’t die back and can bloom late, the plant may also confuse Monarchs by signaling a breeding season when it’s time to migrate.

 

You can help reduce the spread of OE by cutting back Tropical Milkweed plants at the end of summer. Cut them all the way to the ground and dispose of the cuttings to get rid of the parasite.

 

To ensure you’re planting milkweed that will help your local ecosystem and attract native pollinators, always choose a native species!

 


#4. Orange Agoseris

  • Agoseris aurantiaca

Also known as: Orange-flowered False-dandelion and Mountain Dandelion

Orange wildflowers in Idaho

Growing Information

  • USDA Hardiness Zone: Unknown
  • Life Cycle: Perennial
  • Approximate Mature Size: 12-36 in (30-91 cm) tall
  • Bloom Time: Late Summer to Early Fall
  • Sun Exposure: Full Sun

 

The Orange Agoseris belongs to the Sunflower family, which includes asters, daisies, and sunflowers. Its coppery-orange flower heads can be used to make Dandelion beer or wine. You can even eat the leaves!

 

Once this orange wildflower in Idaho has gone to seed, the flower head turns into a white, puffy ball. The wind carries each seed to create new plants.
