This plant can be steeped in tea, and crushed leaves can be a natural mosquito repellant. Bee Balms are hardy, fast growers. So, they don’t require much care to grow, but you’ll have to keep an eye out for overgrowth and trim them back regularly to ensure they don’t overtake your entire garden.

3. Bloodroot

Bloodroots are early bloomers with flowers that start appearing in early spring and become dormant by midsummer. They grow in woodlands and floodplains and prefer moist, well-draining soil in shaded areas.

Bloodroot is known to have medicinal properties and is used for dental plaque and gingivitis. The stem contains reddish sap, which is used as a natural dye for shades of red, orange, and yellow.

4. Common Blue Violet

Scientific name Viola sororia
Colors Violet

Common Blue Violets can be seen throughout Illinois. This hardy plant grows naturally in forests, but they’re also known to thrive along busy roadsides and sidewalk cracks. Due to their hardiness and abundance, they’re often mistaken as weeds. However, these plants benefit the natural ecosystem and attract bees and butterflies.

The flowers and leaves are also edible and can be consumed cooked or raw. They’re often harvested from spring to summer when they’re producing leaves. It’s important to note that the roots are inedible and can cause an upset stomach.

5. Dutchman’s Breeches

Scientific name Dicentra cucullaria
Colors White

Dutchman’s Breeches are easy to identify due to their unique flowers that are shaped like pantaloons. The flowers grow on leafless stalks, and the foliage consists of feathery, deep green leaves.

Dutchman’s Breeches are preferred by bumblebees and other insects with long tongues. They mostly grow in wooded areas and should be handled with care, as all parts of the plant are toxic and can cause mild skin irritation.

6. Goldenseal

Scientific name Hydrastis canadensis
Colors Green and white

Goldenseal belongs to the buttercup family and is known for its medicinal properties. It’s often used to alleviate inflammation and indigestion. It grows abundantly in the eastern half of the US in woodlands.

Goldenseals produce fruit that looks like raspberries, but they’re inedible for humans. The flowers don’t have any petals. Instead, they grow numerous stamens and pistils, and they’re known to attract bees.

7. Jacob’s Ladder

Scientific name Polemonium reptans
Colors Blue

Jacob’s Ladder blooms beautiful bunches of small blue flowers with pops of yellow anthers. Its foliage is a stunning emerald and has small leaves that stick out from the stem and resemble ladder rungs.

Jacob’s Ladders are perennials that grow best in well-draining soil. It prefers partial shade and starts to bloom in early spring. This wildflower requires very little additional maintenance other than deadheading old blooms. It also does well in containers and lasts a while in vases.

8. Liverwort

Colors Blue, pink, white

Liverwort grows well in partial shade and well-draining, moist soil. The flowers come in several different shades and grow like anemones. They grow on hairy stems, and the leaves have a leathery appearance.

Liverwort grows in valleys and wooded areas along streams. While they’re hardy plants, they’re difficult to transplant and grow in new locations. Once they take root and bloom, they’ll attract pollinators, particularly butterflies.

9. Mayapple

Scientific name Podophyllum peltatum
Colors White

Mayapples grow with just two leaves and one flower per plant. You’ll most likely identify these plants by the wide, umbrella-like leaves rather than the dainty white flowers. Mayapples can grow in considerably large colonies in wooded areas.

The plant’s leaves, roots, and seeds are toxic if they’re eaten in large quantities, but small amounts have been used to treat indigestion, jaundice, and fevers. Mayapples bear a yellow fruit that looks similar to a small, wrinkly lemon. The fruit is safe to eat when it’s completely ripe and has toxic properties when unripe.

10. Prairie Trillium

Scientific name Trillium recurvatum
Colors Maroon

Prairie Trilliums are rarer than most other wildflowers, but you can usually find them in wooded areas with a lot of shade. They also grow well in clay soil that’s kept moist. They grow beautiful, wine-colored flowers and have unique leaves with mottled patterns on them.

Once Prairie Trilliums are fertilized, they’ll produce berries that contain seeds. These berries are toxic and shouldn’t be eaten. However, the plant’s young leaves are edible and are often used for medicinal purposes.

11. Shooting Star

Scientific name Dodecatheon meadia
Colors Pink, white

This wildflower is commonly found in the central and eastern US in meadows, prairies, and woodlands. It prefers partial shade but can grow in full sun in cooler climates. It naturally thrives in well-draining soil, but it can grow in clay soil with a little extra care and attention.

Shooting Stars bloom in early spring, and the flowers usually fade by summer. Since the flowers don’t last very long, they should be planted near other plants that bloom later in the summer if you’d like them in an ornamental garden.

12. Solomon’s Seal

Scientific name Polygonatum commutatum
Colors White

Solomon’s Seal produces a line of delicate, white flowers along a single stem. Some varieties will have stems that grow upright, while others will arch. While the flowers are beautiful, they’re quite small and inconspicuous, so Solomon’s Seal’s foliage is more commonly used in spring bouquets.

This wildflower grows best in moist soil with partial to full shade. It prefers receiving morning sun, and the flowers may be too delicate for areas that receive strong afternoon light. It also has medicinal properties and is often incorporated into tea blends.

13. Spring Beauty

Scientific name Claytonia virginica
Colors Pink and white

Spring Beauties produce beautiful white petals with delicate pink stripes on them. They’re hardy wildflowers that grow throughout Illinois, and they’re often regarded as sure signs of spring. Since they grow so well on their own, their absence in wooded areas often indicates severe degradation in the past.

Spring Beauties grow best in loamy soil and partial shade. The flowers bloom fairly early and usually disappear by mid-summer.

14. White Trout Lily

Scientific name Erythronium albidum
Colors White

The White Trout Lily is a perennial flower that grows a single white flower on a flowering stalk. The flowers eventually bend downward, so they appear to grow upside down when you look at them from a distance.

White Trout Lilies grow in most regions in Illinois, except for the northwestern corner of the state. You can mostly find them in woodlands, and they can quickly grow in large colonies if left undisturbed.

15. Woodland Phlox

Scientific name Phlox divaricata
Colors Light blue, violet, white

Woodland Phloxes grow best in wooded areas with moist, well-draining soil and prefer partial shade. They can be quite resilient once they establish themselves and can even grow in clay soils.

This wildflower has a long stem and attracts pollinators with long tongues, such as butterflies and hummingbirds. So, these flowers are a great option if you’re looking to plant a butterfly or hummingbird garden.
