| Edible [1] | May be edible. See the Plants For A Future link below for details. | | Flower Type [1] | Hermaphrodite | | Hazards [1] | Although no specific mention of toxicity has been seen for this species, many plants in this genus contain a narcotic principle, this is at its most concentrated when the plant begins to flower. This principle has been almost bred out of the cultivated forms of lettuce but is produced when the plant starts to go to seed; | | Lifespan [1] | Biennial | | Pollinators [1] | Insects, Lepidoptera | | Structure [2] | Herb |  | | Height [1] | 3.936 feet (1.2 m) |
