Which plant is a winter annual and may be confused with dandelions because the leaves form a rosette in the fall?

• A. Shepherdspurse
• B. Dandelion
• C. Goosegrass
• D. Annual Bluegrass

Answer: (A)

Winter annual weeds germinate in the fall, survive the winter as a low growing rosette, and then flower in the spring. Shepherd’s purse fits this pattern: it sprouts in autumn, stays over winter as a rosette of lobed leaves, and in spring sends up a flowering stem with tiny white blossoms before setting seed. That rosette form in the fall can look very much like a dandelion rosette, which is why they’re often confused. The key difference is life cycle—dandelion is not a true winter annual, and shepherd’s purse produces distinctive seed pods that resemble little purses as it flowers. Goosegrass and annual bluegrass are grasses, not broadleaf plants forming that kind of rosette, so they don’t fit the description.
