Flower
Impatiens parviflora (Small Balsam or Small-flowered Touch-me-not) is a species of annual herbaceous plants in the family Balsaminaceae, native to some areas of Eurasia, naturalized elsewhere and found in damp shady places. Impatiens parviflora can grow in sandy, loamy, and clay soils and prefer moist soil.[1]

Pollination[edit]
Impatiens parviflora flowers are considered hermaphroditic which means that they contain both stamen (male) and pistil (female) structures. These plants are largely pollinated by insects.[2]
Uses[edit]
Impatiens parviflora has many uses. If cooked, the leaves are completely edible. You can eat the seeds either raw or cooked. It is also used as a treatment for warts, ringworm, and nettle stings. Impatiens parviflora is also used for a hair rinse to relieve an itchy scalp.[1]
