Impatiens namchabarwensis (Blue Diamond Impatiens) is a 40–50 cm tall plant, native to the Himalaya. It is an annual plant, although it may live for several years in mild climates that do not freeze in winter.
It was growing at an elevation of 930 m in a very limited area.
Stems are much branched, slightly woody at base; lower stems decumbent, often rooting at nodes.
Flowers are bright ultramarine blue, with small white markings at center and yellow in throat.
It has explosive seedpods, like the other species of the Balsaminaceae family. Seeds are brown when ripe, ca. 1 mm.
The scientific name is sometimes misspelled as "Impatiens namchabawensis".
