Today, we will look at 38 common wildflowers that are purple in Connecticut.


#1. Bull Thistle

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

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.

  • Life Cycle: Perennial
  • Approximate mature size: 1-3′ (30-90 cm)

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.

Common Purple Wildflowers species in Connecticut

Also known as Glaucous Aster and Michealmas Daisy.

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.

#5. Common Burdock

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.

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 Connecticut.

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!


#9. Spotted Knapweed

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

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!

This plant grows in large groups in moist semi-shaded areas and tolerates the sun very well. Many species of wild bees collect pollen from the Creeping Charlie as well.

This purple wildflower is invasive in some places. For example, it is considered an aggressive weed in woodlands and lawns in Connecticut mainly because the plant’s extensive root system makes it difficult to get rid of by hand-pulling or mowing. I have personally battled with Creeping Charlie in my yard before!

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.
