Its chief characteristic is its open airy clumps of yellow flowers. Each "flower" is actually a composite flower, consisting of 4–5 petal-like flowers (strap or ray flowers), each approximately 5–7 mm (0.20–0.28 in) in length. There are no disc flowers. Lactuca muralis grows about 2–4 feet (0.6–1.2 m) tall with the lower leaves pinnately toothed and clasping.
