Growing Guide: Wild Lettuce

Growing Tips

Wild Lettuce thrives in well-drained soil and grows well in full sun to partial shade. It is naturally found in waste areas, along roadsides, and in fields, making it an adaptable herb under a range of growing conditions. Under optimal conditions, plants can reach up to 6 ft. tall and develop a thick, fibrous central stem often tinged with reddish-purple. The long green or bluish-green leaves have toothed or wavy edges and a waxy feel, while the lower leaves gradually drop off as the plant grows. Small yellow flowers resembling dandelions appear in clusters on branching stems from late spring to early fall. After flowering, the plant produces small, dry achenes with fluffy structures that allow the seeds to spread on the wind.
