Flowering - April - June.
Habitat - Open woods, prairies, fields, lawns, waste ground.
Origin - Native to Asia.
Other info. - This small introduced species can be found throughout much of Missouri. The bright yellow flowers are easy to see in the spring as are the bright red fruits that follow. Although the fruits look mighty tasty, they are quite bland and dry and are certainly no substitute for real strawberries, genus Fragaria.
