ROADWEEDS OF THE UPPER PENINSULA
|Sow Thistle (Sonchus arvensis)|
This is the tall "dandelion" that most of us are familiar with. Sometimes the plants can reach five feet, but they are usually around 3-4 feet tall. The seeds and seed heads also resemble dandelions. The leaves are variably shaped but often with prickles. All three Michigan species are from Europe.
