Wild Impatiens

Wild impatiens are widely distributed in South-East Asia and native to the Philippines and Indonesia (Jawa, Sulawesi, Lesser Sunda Islands). This plant is harvested from the wild for local use as a medicine. The tall stature puts the blooms closer to eye level than typical Impatiens and even without flowers, still it is an attractive plant, with its glossy, ribbed leaves.

This plant can be found in lowland and montane forest, growing in gullies, along streams, in damp, shaded and semi-shaded localities, forest clearings, often gregarious, at elevations from 100-1,600 m. It prefers fertile, well-draining soil that's kept evenly moist. Over about 40% humidity is best.

• Flowers - solitary, with slender pedicel and 4-6.5 cm long. The lat­eral sepals are lance-shaped to ovate, 7-12 mm long and acuminate.
