There are at least eight species of Impatiens (Jewelweeds) in the northeast, including native and non-native species, species of temperate and subtropical origins, and wild and planted species. The two native jewelweeds, I. capensis and I. pallida, are common in the region, and I. capensis has been introduced in Europe. Impatiens glandulifera is a non-native species that is locally well established and has the potential to become invasive in the region. The introduced I. balfourii and I. parviflora infrequently naturalize in the Northeast. Three Impatiens species of tropical origins, I. balsamina, I. walleriana, and I. hawkeri, may be able to establish in the Northeast with continued horticultural pressure. We review the descriptions and known distributions of these species, the direct experimental comparisons of their biological traits, and the histories of their introductions and horticultural uses. Such information is beneficial for assessing the invasive potential of these species in the northeast and abroad, and may help to set priorities for control efforts and regulation of horticultural uses.
