    Spiderwort (Tradescantia) is a New World genus of herbaceous perennials, named by Carl Linnaeus in honor of John Tradescant the Elder (ca. 1570–1638). Although all spiderworts listed in New York are considered to be native to eastern North America, none are listed as New York natives by the New York Flora Atlas.

        Tribe Commelineae
        The Commelineae in New York include the dayflowers (Commelina spp.) and dewflowers (Murdannia spp.).
          Commelina
          Commelina erecta L.
          slender or whitemouth dayflower
          The only dayflower (Commelina sp.) listed as native to New York is Commelina erecta (slender dayflower),[1] which is thought to be extirpated from the state.

          The introduced Asiatic dayflower (Commelina communis) is fairly common in many parts of the state. It is reported to be invasive in Pennsylvania, Maryland, West Virgina, Virginia, and Kentucky.[2]

              water hyacinth
              Eichhornia crassipes (water hyacinth) is an attractive free-floating aquatic perennial that is known to be very invasive in the south. It has been reported outside of cultivation in New York State, but it's not able to overwinter this far north. However, it may be able to grow as an annual, and there is concern that water hyacinths may eventually evolve resistance to the cold.[1][2]
