Several studies on diverse plants like petunia, tomato, impatiens, maize etc. But hummingbirds are not the only pollinators of "Impatiens capensis". Flowers of "Impatiens capensis" have these nectar spurs. Due to hummingbirds and bees, the pollination of "Impatiens capensis" is very high. Virus members include the tomato spotted wilt virus and the impatiens necrotic spot viruses. Most "Impatiens" species are annual or perennial herbs with succulent stems. Most "Impatiens" species are perennial herbs. "Erythranthe guttata" is pollinated by bees, such as "Bombus impatiens". Curvature angles of nectar spurs of "Impatiens capensis" are variable. Parasitic plants that use impatiens as hosts include the European dodder ("Cuscuta europaea"). Impatiens glandulifera is a large annual plant native to the Himalayas. "Bombus impatiens" are hosts to other bees. "Impatiens parviflora" has many uses. The genus "Impatiens" is characterized by a large variety of flower architectures. The zygomorph flowers of "Impatiens" are protandric.
