Wildflowers are a type of flowers that form in the wild, without any assistance from people.
Some may choose to plant wildflowers in their backyards, but in most cases, wildflowers are native. They can grow in a lot of different environments, like wetlands, meadows, and forests.
Native plants are important for nature, as they provide nutrients and shelter for many animals, as well as humans.
There are a lot of wildflowers that grow around North America, some of which are more common in certain states. You’ll find some examples of common wildflowers seen in the state of Oklahoma, which all have distinct colors, fragrances, and characteristics.
As you go through this list, keep in mind that some of the wildflowers in this post are invasive species, so they shouldn’t be planted in your home’s garden.
