Of many hundreds of species,m only a few are usually seen in gardens.Most of these are annuals or tender perennials treated as annuals; all are valuable for long summer bloom.When lightly touched, ripe seed capsules burst open and scatter seeds.
A varied group of striking perennials usually grown as annuals; they were developed from a number of species native to New Guinea, especially Impatiens hawkeri (Impatiens schlechteri). Plants can be upright to spreading; most are 1 to 2 ft. tall and as wide or wider. Leaves are typically large, often variegated with cream or red. Flowers usually large (3 in. wide) though not profuse, held well above foliage; colors include lavender, purple, pink, red, orange, and white. Once considered primarily pot plants, they may also be grown in the open ground; provide ample fertilizer and give somewhat more sun than you would common impatiens (Impatiens wallerana).
