There are hundreds of species of Impatiens, though four are much more commonly grown in gardens than the rest{{SSN}}. Most are annuals, or perennials treated as annuals{{SSN}}. They are grown for their flowers, which continue until frost. When the seed capsules are ripe, they explode upon being lightly touched, shooting little seeds around.{{SSN}}

They are grown for their flowers, which continue until frost. When the seed capsules are ripe, they explode upon being lightly touched, shooting little seeds around.{{SSN}} Stems are usually succulent{{RHS}}, and flowers, which may be solitary or in groups, usually have 3 (or rarely 5) sepals{{RHS}}. In some species the lowest sepal is large and extended backwards into a spur{{RHS}}.

Need moist soil, good drainage, humus-rich soil, as well as a cool site (except for I. mirabilis){{RHS}}. Perennials should be kept relatively dry in the winter dormancy period{{RHS}}. Pinch plants regularly if you want to keep them bushy{{RHS}}, otherwise some can get leggy. For tall-flowering I. balsamina shoots, remove the side shoots and initial flower buds{{RHS}}.

Most are frost tender, but ''[[Impatiens glandulifera|I. glandulifera]]'', ''[[Impatiens noli-tangere|I. noli-tangere]]'' and ''[[Impatiens capensis|I. capensis]]'' can not only survive, but self-sow where winter temperatures drop to -15°C (5°F){{RHS}}. These species can also become invasive in ideal conditions.

Seed can be short lived in some species{{RHS}}, sow as fresh as possible. Softwood cuttings can be taken of plants you like{{RHS}}.
+
+
Seeds of frost-sensitive sorts should be planted under glass in spring, then picked out and planted in individual pots of loamless or loam of medium fertility{{RHS}}. Grow in a sunny, airy spot, free of frost, and pinch to keep compact{{RHS}}. Plant outdoors only after danger of frost is passed, and water well.

Softwood cuttings can be taken in spring, and placed in soilless potting mix, best with some bottom heat{{RHS}}.
