Tall Blue Lettuce vs Woodland Lettuce
These species are sometimes confused in the limited zone in which their ranges overlap, but are easily distinguished by differences in flower size and bloom timing. Both tend to grow in partly-shaded, moist, disturbed habitats in rich soils, and for the most part, L. biennis is the more northerly species occupying a similar niche as L. floridana, the more southerly species. Where they overlap, L. floridana tends to prefer shadier, moister, and slightly less disturbed habitats than L. biennis.
