Wild Lettuce (Lactuca virosa) is grown medicinally for the milky white sap that oozes from the plant when cut or broken. 

Germination and Growing instructions: 
Scatter seeds on moist soil, and press lightly into the soil. Do NOT cover the seeds as Lactuca needs sunlight to germinate. Germination takes 5 days to two weeks. 

Transplant seedlings to rich, moist soil and full sun, spacing them 2 ft apart. 
Wild Lettuce is a biennial, which means in the first year it will make a rosette of leaves, and in the second year the flower stalk(s) will shoot up in early to mid summer to 4-6ft and produce seeds in late summer/early fall. If you're lucky, it will make seeds the first year. 

Wild Lettuce is hardy to zone 6 (-10F/-23C).
