Wall lettuce (Mycelis muralis ) is an introduced annual, biennial or perennial herb often found in the garden, in cracks in rocks and in disturbed areas around Leaning Oaks. It is yet another yellow-flowered introduced weed in the garden, and like Dandelion, Hairy Cat's Ear and Sow Thistle, it is spread by wind borne seeds. It was formerly included in the genus Lactuca which includes the familar garden lettuce, and like those species has a milky sap.
