Tall Rattlesnakeroot (Nabalus altissimus) vs. Three-leaved Rattlesnake Root (Nabalus trifoliolatus)

Updated August 24th, 2026

These two species are visually similar and frequently confused. They can be distinguished by flowers, lower leaf shape, and with some effort, by seeds. N. altissimus ranges much farther west, farther north, and slightly farther south, and prefers slightly shadier habitats. N. trifoliatus extends farther east (closer to the coast) in the central portions of its range, prefers slightly sunnier habitats, and is tolerant of some soil salinity.

Tall Blue Lettuce (Lactuca biennis) vs. Woodland Lettuce (Lactuca floridana)

Updated August 3rd, 2026

These species are easily confused in the limited zone in which their ranges overlap. They can usually be distinguished by differences in flower size and seeds. They have differences in leaf shape and bloom time, but with some overlap in both characteristics. 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, but L. floridana ranges farther north in the central US, and L. biennis is also found in the West. Where they overlap, L. floridana tends to prefer shadier, moister, and slightly less disturbed habitats than L. biennis.

Jumpseed (Persicaria virginiana) vs. Asian Jumpseed (Persicaria filiformis)

Updated July 14th, 2026

These species are visually similar and are easily confused. The confusion is worsened by nurseries mislabeling P. filiformis as P. virginiana. They can be distinguished by leaf shape, chevron pattern, and flower color. Some plants are cultivars that are easily identifiable as P. filiformis, but wild-type plants warrant closer examination. P. filiformis is less common throughout, but mostly found in the same range and similar habitats to P. virginiana.
