 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.

 One of the sure signs of spring at Leaning Oaks is the sound of the first singing Orange-crowned Warblers (Oreothlypis celata). Their arrival here in the last week of March is more or less timed to the blooming of the Big Leaf Maple, which are the same yellow-green as the lutescens subspecies of Orange-crowns. Once in a while an individual linger into the winter months, but most disappear by the 3rd week of September. Orange-crowned Warblers are most often seen foraging in the Oceanspray (133) or bathing in the stream we built. It is one of our most abundant warblers on the property and its dry trill a common sound from April to July.
