Impatiens

Impatiens /ɪmˈpeɪʃəns/ is a genus of about 850 to 1,000 species of flowering plants, widely distributed throughout the Northern Hemisphere and the tropics. Together with Hydrocera triflora, impatiens makes up the family Balsaminaceae.

Common names include impatiens, jewelweed, touch-me-not, snapweed, and, for I. walleriana in Great Britain, "busy lizzie", as well as, ambiguously, balsam. As a rule-of-thumb, "jewelweed" is used exclusively for Nearctic species, "balsam" is usually applied to tropical species, and "touch-me-not" is typically used in Europe and North America.
