It was originally collected in Zanzibar in 1865 and was named Impatiens Sultana to honor the sultan of Zanzibar. Sultana is a popular name for the flower.
Impatiens is Latin for impatient a fact that is attributed to the act of sudden discharges of seeds from the ripe seed capsules.
Many gardeners, especially when they were children, love to touch or squeeze the green seed pods gently and watch the seeds pop out.
Other common names are Touch-me-nots and Jumping Betty.
