New Guinea Impatiens: Big Blooms, Bold Foliage, Easy Care

Botanical Name: Impatiens × hawkeri hybrids

These hybrids deliver a shrubby habit, large single flowers (5 flat petals) in pink, red, mauve, and white, and stunning foliage — lance-shaped leaves often tinged red-bronze or splashed with bright green or yellow. Perfect for bright windowsills, sunrooms, or summer patios (shaded from hot sun).

Keys to Continuous Bloom

Light: At Least 4 Hours Bright Indirect

Insufficient light = no flowers. Indoors, a sunny window (no direct summer sun) or summer outdoors in shade works.

Water Consistently

Keep soil evenly moist, not soggy. Flowering plants in pots dry fast — check often. Wilting = too dry.

Deadhead and Pot-Bound

Cut faded flowers promptly. Repot only when roots fill the pot (fall after flowering) — they bloom best slightly pot-bound.
