16 types of purple wildflowers in Nevada:

 


#1. Bull Thistle

  • Cirsium vulgare

Types of Purple Wildflowers found in Nevada

Also known as Boar Thistle, Common Thistle, Dodder, and Spear Thistle.

Growing Information

  • USDA Hardiness Zone: 3a-8b
  • Life Cycle: Biennial
  • Approximate mature size: 2-6′ (.6-1.8 m)
  • Bloom Time: Summer, Fall
  • Sun Exposure: Full Sun, Sun to Partial Shade

 

Bull Thistle is a spiny and common purple wildflower in Nevada.

 

So be careful if handling! It’s also a great flower if you want to attract giant bees and butterflies.

 

The seeds of this thistle are the preferred menu item for the American Goldfinch. However, these birds also use the thistledown to line their nests; thus, they wait until the flowers bloom in late summer to raise their young.

 


#2. Alfalfa

  • Medicago sativa

Purple Wildflowers species that live in Nevada

Also known as Lucerne.

Growing Information

  • USDA Hardiness Zone: 3a-11
  • Life Cycle: Perennial
  • Approximate mature size: 1-3′ (30-90 cm)
  • Bloom Time: Spring, Summer, Fall
  • Sun Exposure: Full Sun

 

Farmers often plant alfalfa as a food crop for farm animals, and it fixes nitrogen from the air into the soil through its roots.

 

This purple wildflower is native to warmer climates and attracts many bees, butterflies, and birds.

 


#3. Smooth Blue Aster

  • Symphyotrichum laeve

Common Purple Wildflowers species in Nevada

  • Bloom Time: Summer, Fall
  • Sun Exposure: Full Sun, Partial Sun

 

You will find this striking purple wildflower in plains, meadows, and hillsides throughout Nevada.

 

Like the hairs on a dandelion, the Smooth Blue Aster pappi (ring of fine feathery hairs surrounding seeds) allows the seeds to be spread by the wind.

 


#4. Winter Vetch

  • Vicia villosa

Nevada Purple Wildflowers species

Also known as Vicia Species, Fodder Vetch, and Hairy Vetch.

  • Approximate mature size: 1-3′ (30-91 cm)
  • Bloom Time: Summer, Fall

Often gardeners plant Winter Vetch as a companion plant to tomatoes. This is done because the Winter Vetch helps put nitrogen in the soil, which helps keep weeds from sprouting.

 

This purple wildflower grows in various places such as forests, grasslands, meadows, old fields, roadsides, and disturbed areas. It also is considered invasive in some areas.

 


#5. Common Burdock

  • Arctium minus

purple wildflowers

Growing Information:

You will find this purple wildflower in pastures, open prairies, hayfields, roadsides, old fields, barnyards, railways, and other disturbed areas in Nevada.

 

Common Burdock has large leaves and deep purple flowers resembling rhubarb, making this plant easy to identify. After the flower head dries, they are similar to velcro because they stick onto humans and animals to transport the entire seed head.

 

This purple wildflower attracts bees, butterflies, and birds. Powdery mildew and root rot often affect it. But be careful if you handle this plant; it may cause skin irritation or an allergic reaction.

Also known as Wild Bergamot, Horsemint, and Wild Bee Balm.

Growing Information

  • USDA Hardiness Zone: 3a-9b
  • Life Cycle: Perennial
  • Approximate mature size: 2-4′ (60-120 cm)
  • Bloom Time: Summer
  • Sun Exposure: Sun to Partial Shade

 

Look for this fragrant clump-forming perennial with beautiful lilac-purple wildflowers in dry areas of fields, prairies, and along roads in Nevada.

 

Bee Balm leaves make a refreshing tea that provides many health benefits, as its antimicrobial properties help ward off colds and the flu. Steaming the plant can also help clear nasal passages, while creating a poultice from Bee Balm could prove helpful in treating headaches, sores, muscle cramps, or fungal infections. Lastly, Monarda can stimulate uterine contractions, so expecting women shouldn’t use it.

 

The main reason that I grow Bee Balm in my flower garden is to attract hummingbirds, butterflies, and pollinator bees. When this NATIVE perennial is in full bloom, birds and insects won’t be able to resist visiting the nectar-rich flowers. Many people claim that Bee Balm is so effective at drawing in hummingbirds that they no longer have to worry about filling their feeders!

You will usually find these wildflowers along roads and open fields throughout Nevada.

 

This purple wildflower is considered a weed in many places because it can crowd out other plants. However, it is also an allelopathic plant, which chemically changes the soil to discourage other plants from growing and favor its offspring. I can’t believe how rude Spotted Knapweed can be, but it is an effective evolutionary advantage!

It’s hard to believe this is an invasive plant, but this purple wildflower is considered a weed because it takes over and pushes out native plants.

In some areas, this plant is considered invasive. However, the young leaves of this spring-blooming flower are high in Vitamin C, can be eaten in salads, and have a slightly bitter taste.

 

Dame’s Rocket is often confused with native Phlox species with similar large flower clusters. However, you can tell the difference between them by Dame’s Rocket has alternately arranged leaves and four petals per flower, while phloxes have opposite leaves and five petals.
