New Guinea Impatiens (Impatiens hawkeri) is a tender flowering perennial, usually grown as a seasonal bedding or container plant in India. It is prized for its unusually large, flat flowers in shades of red, pink, orange, coral, purple and white, set against thick, lance-shaped leaves that are often tinted bronze or variegated.
Compared with the common Balsam (Impatiens balsamina), the New Guinea types are bushier, bloom almost continuously and tolerate brighter light. In most Indian cities they perform best in the cooler months and in the partial shade of a balcony or verandah, where they flower freely with minimal effort.

| Fertilizer |
Feed every 2-3 weeks in the growing season with a balanced liquid fertilizer for continuous flowering. |
| Pruning |
Pinch growing tips to encourage bushiness; remove spent flowers and leggy stems to keep plants compact. |
