DescriptionTwinleaf (Jeffersonia diphylla) is a low plant found in moist forests and floodplains of eastern North America, including southern Ontario. Its fruit is a pear-shaped capsule that opens with a lid at the top. Twinleaf’s genus name, Jeffersonia, commemorates Thomas Jefferson, the third president of the United States, who had a wide knowledge of natural history and was an enthusiastic supporter of scientific expeditions. The species name and the common name both refer to its “twin” leaflets (di = two; phylla = leaves), which resemble somewhat a pair of butterfly wings. The leaves are not fully expanded until after the twinleaf plant has flowered.
