Colorful wildflowers blooming in Illinois' woodlands are a delight to behold! Nearly every week of spring and summer you can observe new species.
 
What is a wildflower? It is a plant with an herbaceous (not woody) stem. It produces flowers that are easily seen, and it grows naturally in native habitats.
 
Wildflowers growing in forested areas must be able to survive changing conditions. They adapt to these changes in several ways. Some woodland wildflowers complete their life cycle in early spring. They grow quickly, flower and produce seeds in a short period of time. By doing so, they are able to take advantage of sunlight that will soon be blocked when leaves on large trees unfurl. The seeds of these wildflower species can survive until conditions for growth are favorable, most likely the next spring.
 
Several species grow from underground structures that store food produced during the short growing season. Other wildflowers of woodland habitats are adapted to conditions of low light, blooming later in the year and for a longer period of time. Those wildflowers growing near the edge of woodlands have access to more light than interior woodland species.
 
Here are some of the native woodland wildflowers that you can find in Illinois.
