Lactuca saligna, commonly known as willowleaf lettuce or least lettuce, is an annual herb that is native to a variety of habitats in Eurasia, including open woodlands, grasslands, and disturbed areas. It has been introduced to North America, where it can be found in similar disturbed habitats. This plant typically grows up to 3 feet tall and features spindly, erect stems with long, narrow, willow-like leaves. The inconspicuous yellow flowers bloom in the summer and are followed by small, dandelion-like seed heads.

Willowleaf lettuce is not commonly cultivated but may be of interest for naturalized areas or wildflower gardens where it can be allowed to self-seed. It is drought-tolerant and can thrive in poor, well-drained soils, making it suitable for xeriscaping. In cultivation, it requires minimal care, thriving in full sun to part shade. However, gardeners should be cautious as Lactuca saligna can become weedy and potentially invasive outside its native range. It is advisable to check local regulations before planting to ensure it is not considered invasive in your area.CC BY-SA 4.0
