Wild or Opium Lettuce (Lactuca virosa) is grown medicinally for the milky white sap that oozes from the plant when cut or broken. Every order will receive 25-30, non-GMO seeds. Germination and Growing instructions: Soak the seeds in water overnight then scatter seeds on moist soil and press them lightly into the soil. Do NOT cover the seeds as Lactuca needs sunlight to germinate properly. Germination can take anywhere from 72 hours to two weeks but usually four to six days if the seeds are soaked overnight. 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).
