Impatiens balsamina (garden balsam, garden jewelweed, rose balsam, touch-me-not) is a species of Impatiens native to southern Asia in India and Burma. Other common names include ‘elepe in Hawaiian, mírame lindo in Spanish, and kamantigi in Chamorro.

It is an annual plant growing to 20–75 cm tall, with a thick, but soft stem. The leaves are spirally-arranged, 2.5–9 cm long and 1–2.5 cm broad, with a deeply toothed margin. The flowers are red, pink, purple, or white, and 2.5–5 cm diameter; they are pollinated by bees and other insects, and also by nectar-feeding birds. The ripe seed capsules undergo explosive dehiscence.

This is the first flower I ever plant as a little girl. And now our backyard has a few left though I am barely at home. When I first discovered it from my great uncle's backyard and transplanted it to our yard, we never knew it would flourish the next 5 or more years. The thing about this flower is that it would grow by itself and didn't need any care.
