Scientific Name: Malaxis unifolia
USDA Hardiness Zone: 3 – 10
Average Mature Size: 20 inches

Green Adder’s Mouth might not be the most aesthetically pleasing wildflower in Tennessee, but the state doesn’t have a shortage of them. The plant typically has large leaves near the base, and the flower extends out of that leaf. Sometimes, the plant can reach up to 20 inches off the ground, but it has a very small spread.


6. Giant Coneflower

Giant coneflower in the yard

Scientific Name: Rudbeckia maxima
USDA Hardiness Zone: 5 – 9
Average Mature Size:
5 – 7 feet

Few wildflowers can grow higher than the average human, but the Giant Coneflower is one of them. These plants can grow up to 7 feet off the ground, and each stem produces only a single yellow flower. The petals usually point downward, and the Giant Coneflower will grow in bunches.


7. Common Blue Violet

Common Blue Violet plan

Scientific Name: Viola sororia
USDA Hardiness Zone: 3 – 10
Average Mature Size:
4 inches

“Common” is right in the name of the Common Blue Violet, and you can find them all over the place in Tennessee. Unlike many of the wildflowers on our list that reach far into the sky, the common blue violet usually only reaches about 4 inches off the ground. And while they might be common wildflowers, their bright purple petals make them extremely beautiful.


8. Tall Hairy Agrimony

Scientific Name: Agrimonia gryposepala
USDA Hardiness Zone: 3 – 9
Average Mature Size:
5 feet

Technically a part of the rose family, the Tall Hair Agrimony doesn’t bear much resemblance. They grow on long stalks that can reach up to 5 feet high, and they have tons of small yellow flowers throughout. They typically bloom between June and September.


9. Clustered Mountain Mint

Scientific Name: Pycnanthemum muticum
USDA Hardiness Zone: 4 – 8
Average Mature Size:
1 – 3 feet

Clustered Mountain Mint has a strong mint smell, and it works great as an insect repellant. They also do a great job of attracting butterflies, making them a favorite addition to many backyard gardens.


10. Lesser Periwinkle

Common periwinkle plant

Scientific Name: Vinca minor
USDA Hardiness Zone: 4 – 8
Average Mature Size:
3 – 6 inches

Common Periwinkle often goes by the name dwarf periwinkle, and it’s a small wildflower you can find throughout Tennessee. The tallest varieties sit just 6 inches off the ground, bringing blue or purple flowers.


11. Yellow Trefoil

Yellow trefoil growing in the yard

Scientific Name: Medicago lupulina
USDA Hardiness Zone: 3 – 9
Average Mature Size:
2 – 3 feet

Many people call it Yellow Trefoil, or Black Medick, but no matter what you call it, it’s a type of clover. They spread like crazy, and they bloom with small yellow flowers. They’re extremely invasive, and if you have some in your garden, it’s likely to try and take over everything.


12. Fire Pink

Fire Pink plant in the garden

Scientific Name: Silene virginica
USDA Hardiness Zone: 4 – 8
Average Mature Size:
1 – 2 feet

Fire pink doesn’t bloom for long, but with bright red flowers, it’s an interesting-looking wildflower when it does. The flowers themselves consist of five petals that form a star. They have a limited temperature tolerance, but if they can survive the temperatures, they don’t need much space to thrive.


13. Teasel

Teasel plant in the garden

Scientific Name: Dipsacus
USDA Hardiness Zone: 3 – 8
Average Mature Size:
2 – 8 feet

Teasel is another invasive species in Tennessee, and they’re not the most aesthetically pleasing. They’ll have trace amounts of purple when in full bloom, but for the most part, they’re brown. The most astounding part of these plants is how tall they can get, with some varieties growing up to 8 feet tall.


14. Blue Toadflax

Blue Toadflax with blue sky backdrop

Scientific Name: Nuttallanthus canadensis
USDA Hardiness Zone: 4 – 8
Average Mature Size:
1.5 feet

You can find Blue Toadflax all along the East Coast from Canada to Texas, and Tennessee is no exception. This wildflower grows in thin stalks that quickly climb, and they have tons of blue, purple, and sometimes white flowers when they’re in bloom.


15. Red-Center Prickly Pear

Red-center prickly pear plant

Scientific Name: Opuntia cespitosa
USDA Hardiness Zone: 4 – 11
Average Mature Size:
6 – 12 inches

The Red-Center Prickly Pear is actually a type of cactus, and very few varieties can survive in Tennessee. However, some varieties make it in the warmer parts of the state. These plants don’t look like much when they’re not in bloom, but when they flower, they produce gorgeous large yellow and red blooms.


16. Virginia Bluebells

Scientific Name: Mertensia virginica
USDA Hardiness Zone: 3 – 8
Average Mature Size:
1.5 – 2 feet

Sure, Virginia is in the name, but that doesn’t mean you can’t find these plants in Tennessee. They love the warmer climate, and when they bloom, their clusters of blue bell-shaped flowers are breathtaking.


17. Wood Anemone

Wood anemone growing in the garden

Scientific Name: Anemone nemorosa
USDA Hardiness Zone: 3 – 8
Average Mature Size:
1 foot

Wood Anemone is what many people think of when they think of a wildflower. They’re smaller plants with white flowers and grow in bunches. They flower in early spring, and they will quickly spread throughout your yard or garden if you have them.


18. Red Bee Balm

Red bee balm fower

Scientific Name: Monarda didyma
USDA Hardiness Zone: 4 – 9
Average Mature Size:
2 – 4 feet

Red Bee Balm gets its name because folklore deemed crushing these leaves and applying them to a bee sting would help with swelling. While there’s little evidence to support this, though, the name stuck. The plant itself has bright pink petals, and you can crush the leaves and add them to tea.
