| Identification | Canada Lettuce should be familiar to most readers, with its weedy aspect, raggedly cut and lobed leaves, and open inflorescence of small yellow heads. Our only other native yellow-flowered wild lettuce is L. hirsuta, which differs in its pubescent stem (vs. smooth or nearly so) and blunt-lobed and blunt-tipped leaves (vs. pointy lobed and tipped). As with others in the genus, some plants can reach up to 8-9 feet tall. This is, by far, the most frequently encountered Lactuca in the state. | |
