  • Bold variegated foliage and large coral flowers make Celebrette ‘Light Coral’ New Guinea impatiens a real attention grabber. Here it’s combined with ‘Gartenmeister Bonstedt’ fuchsia and Sweet Caroline ‘Bronze’ ipomoea.

  • Cool shade

    Maroon coleus makes a perfect partner for bronzy red-leafed Celebrette ‘Strawberry Star’ and dark green-leafed Celebrette ‘Scarlet Improved’ New Guinea impatiens.

 

Among the New Guinea impatiens and related hybrids are six that we grew and liked in Sunset's test garden. Their flowers, which now come in a broader color range than ever before, vary from brilliant solid hues to bicolors and measure about 3 inches across.

Great combos

New Guinea impatiens look particularly striking mingled with coleus, heuchera, and other colorful foliage plants that thrive in part sun.

• Celebrette 'Purple Improved' and Magilla 'Purple' perilla

• Infinity 'Scarlet' with 'Black Heart' ipomoea, red-leafed Abyssinian banana, and 'Troy's Gold' plectranthus

• Paradise 'Orchid' with 'Illustris' colocasia, lime green coleus, and 'Purple Ruffles' heuchera

• Sonic 'Cattleya' with maroon and pink 'Kingswood Torch' coleus and 'Margarita' ipomoea

• SunPatiens 'Tropical Ice' with Chinese taro and white bacopa

Care

Temperature. Plant after the soil warms and nighttime temperatures are above 50°. In general, plants stop blooming when temperatures soar to 85° or more. In hot, inland areas, choose plants from one of the heat-resistant series ― Celebrette, Fanfare, or SunPatiens.

Sun. New Guinea impatiens need some sun to bloom well. Choose an area that gets morning sun and afternoon shade (protect from midday sun). In cool, coastal areas, plant in full sun.

Soil. Plant in soil that's well drained but not too rich. Mix in an organic or a controlled-release fertilizer low in nitrogen.

Water. Keep the soil moist but not soggy.
