Lactuca – Lettuce –
This widespread genus of around 100 species is best represented in temperate Eurasia. It includes a number of weed but is best known in the from of Lactuca sativa-the common lettuce- which appears to have been in cultivation for least 5,000 years and is thought to be derived from the weedy ‘Prickly Lettuce’, L. serriola, whose seeds also yield an edible oil. Species may be annual, biennial, or perennial and range in size from 4″ to 6′ feet high. If allowed to flower, it quickly becomes apparent that lettuces are in the daisy family, they have large sprays of small blooms, often mauve or yellow.The non-edible species contain very bitter compounds that have sedative properties and some have been used medicinally.
They are easily grown in any moist but well drained soil in full sun or part shade. In cool climates sow seed from early spring to late summer, in warm climate from fall to mid spring, though some heat tolerant varieties can be grown in summer. For tender, succulent leaves it is important that there be no check in growth, so ensure soil remains moist. Shade young plants in hot weather and feed at intervals with weak liquid manure.
