  • Except for three species in South America, all Helianthus species are native to North America. (wikipedia.org)
  • producers
  • Some of these species affect the producers' ability to increase seed production and thus have become economic pests. (ndsu.edu)
  • Small
  • Helianthus elongatus Small, Fl. (usf.edu)
  • A good butterfly garden needs a variety of nectar plants that will produce continuous blooms throughout the season, including both tall and short species and large and small flowers, Janis says. (dailypress.com)
  • Helianthus eggertii was first described by John Kunkel Small in 1903 in his Flora of the Southeastern United States. (wikipedia.org)

  • Spatial Relationships of Helianthus paradoxus (Compositae) and associated salt marsh plants. (wikipedia.org)
  • Given our economic zeitgeist, it isn't hard to imagine hordes of people trampling the countryside, harvesting wild plants like strip miners-decimating species, destroying habitat and frantically hastening our own demise. (wordpress.com)
  • wild
  • In 2004-2008, 400 accessions of these wild species were evaluated using the most effective artificial inoculation procedure with a combination of ascospores and ground sclerotinia-infected millet seed. (usda.gov)
  • found
  • Among weed species, the greatest reduction was observed for Papaver rhoeas L., with full inhibition recorded at a concentration of just 5% DM w/v. Complete inhibition was also found for other weed species, but at higher concentration. (sggw.pl)
  • Helianthus eggertii is only found in the Interior Low Plateaus area of Tennessee, Kentucky, and Alabama, where it lives in barren forest openings. (wikipedia.org)
  • Helianthus paradoxus (paradox sunflower, puzzle sunflower, Pecos sunflower) is a threatened species of sunflower found only in west Texas, Utah, and New Mexico salt marshes by the edges of inland salt lakes and salt flats. (wikipedia.org)
  • Helianthus paradoxus is found in areas with salinity levels range from 10 to 40 parts per thousand. (wikipedia.org)
  • range

  • Any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range. (usf.edu)
  • large
  • As the large, yellow-gold heads of many species tend to follow the sun, the Italian-derived 'girare-sole', literally meaning 'turning sun', is also a cognate with 'Jerusalem', as in Jerusalem Artichoke. (wikipedia.org)
  • work
  • The objective of this work was to study the effect of allelocompounds contained in leaf extracts (at five concentrations: 1.25, 2.5, 5, 7.5 and 10% DM w/v) of the 'Ogrodowy' variety of sunflower on the germination of 33 weed species. (sggw.pl)
