Impatiens hawkeri aka Impatiens

Impatiens hawkeri is known as New Guinea impatiens. It belongs to the balsam family, Balsaminaceae. Its native range runs from New Guinea to the Solomon Islands. It grows in damp mountain forests, often near streams and rivers. These sites offer shade or part shade in a wet tropical climate. Wild forms vary in flower color and leaf shape. Growers also raise it as an ornamental plant.

This soft-stemmed perennial often serves as an annual bedding plant. It forms a mound with stems that branch. Some stems stand upright, while others lie along the ground. Garden plants reach about 0.5–2 feet [0.15–0.61 metres] tall. They spread about 1.5–3 feet [0.46–0.91 metres] wide. Another account gives heights up to 3.3 feet [1 metre]. Growth is moderate, and the stems may show red tints. The simple leaves grow in opposite pairs or whorls. Their shapes range from oval to narrow and pointed. The edges have rounded teeth with small, stalked glands. Leaves may show bronze or purple tints, or mixed colors. Their lower faces often look red or purple.

Single flowers sit on long stalks and bear a clear spur. Flower colors include pink, red, orange, white, and purple. Garden plants bloom from spring through fall and attract butterflies. In tropical settings, plants can flower and set seed year-round. The fruit is a ribbed capsule with a fleshy texture. Ripe capsules burst open and curl inward, scattering their seeds. Growers can raise new plants from seed.

Part shade suits this plant best, though it tolerates deeper shade. It can also grow in sun with enough water. Protect it from the hottest sun for better growth. Use moist soil rich in organic matter that drains well. Plants need more water as sun exposure rises. NC State lists hardiness in USDA zones 10–12. Gardeners use it in beds, borders, pots, and hanging baskets. It also suits small spaces beside patios and paths.

NC State reports no major insect or disease problems. It lists resistance to downy mildew and phytophthora. Useful Tropical Plants records no known hazards or food uses. NC State marks it as non-toxic to cats, dogs, and horses. Traditional medicine uses include cooked plants for children's stomach pain. Leaves also feature in a mixed-plant rub for labor pain. These records describe local uses, not proof of safe treatment.
