Please be aware that today I’m ONLY listing and focusing on the most COMMON plants. There are so many species, varieties, and subspecies that it would be impossible to name them all. But if you want to dive deeper into all the white wildflowers in Oklahoma, check out this field guide!
Here are 17 different WHITE wildflowers found in Oklahoma!
#1. Common Chickweed
- Stellaria media
Also known as: Chickenwort, Winterweed, Starwort
Growing Information

Despite being native to North America, this white wildflower is considered an aggressive weed in Oklahoma.
You’ll likely find it in dry, rocky woods, meadows, and prairies. Unfortunately, it also thrives on farms where it’s known to reduce the yield of corn, soybeans, and other crops.
In addition to its invasive nature, all parts of Indian Hemp are highly toxic to humans, dogs, and livestock. Avoid touching the milky sap, which can cause blisters on your skin. Its stiff, reddish stems and bushy lance-shaped leaves will help you identify this plant.
The small white flowers are rich with nectar, so don’t be surprised to see lots of butterflies and moths where Indian Hemp grows.
#7. White Trout Lily
- Erythronium albidum
Also known as: White Fawnlily, White Dog’s-tooth Violet, Yellow Snowdrop, Adder’s Tongue
Growing Information
- USDA Hardiness Zone: 3-8
- Life Cycle: Perennial
- Approximate Mature Size: 6-12 in (15-30 cm) tall
- Bloom Time: Spring
- Sun Exposure: Partial Sun
The elusive beauty of a White Trout Lily flower lasts for only two weeks in mid-spring. This plant forms impressively large colonies on forest floors, serving as nutrient pools for the soil. However, only a few mature plants will bloom at a time.
Look for White Trout Lily in deciduous woodlands where it’s native. It blooms into a single white flower with bright yellow anthers or pollen fronds. Mature plants have two dark green leaves with mottled purple blotches.
If you want to attract bees, butterflies, and skippers to your garden, you can purchase White Trout Lily plants from your local nursery. Seeds, on the other hand, will take about four years to bloom. This plant prefers partial shade and deep, loamy soils.
