Prickly Lettuce
Lactuca serriola
In the United States:
Invasive
· also called wild lettuce, compass plant
Listed as invasive. Check local regulations — several jurisdictions restrict planting.
Honeybees forage on prickly lettuce for small amounts of nectar and pollen during its summer-to-fall flowering period, with peak bloom in late summer in temperate zones. This tall annual thrives in full sun on disturbed, dry soils and can reach 6 feet, offering incidental support to colonies in weedy habitats. While primarily self-pollinating, it draws some insect visitors, but beekeepers may need to manage its spread in apiary vicinities.
