Plant Details

Of the hundreds of species, only the following are usually seen in gardens. Most of these are annuals or tender perennials treated as annuals; all are valuable for long bloom period (most flower in summer, and a few continue into fall).

impatiens New Guinea hybrids

  • Perennials in Zone TS; USDA 10-11; annuals anywhere.
  • A varied group of striking plants developed from a number of species native to New Guinea, especially Impatiens hawkeri.
  • Plants can be upright or spreading; most are 12 feet tall and as wide or wider.
  • Leaves are typically large, often variegated with cream or red.
  • Flowers usually large (212 inches wide) though not profuse, held well above foliage; colors include lavender, purple, pink, red, orange, and white.
  • Once considered primarily potted plants, they also perform well as bedding plants; provide ample fertilizer and give somewhat more sun than you would Impatiens walleriana.

Popular strains include 'Celebration' (with 3 inches flowers), 'Paradise', 'Sunshine', and 'Pure Beauty'. Most New Guinea hybrids are cutting-grown plants, but 'Spectra' ('Firelake') and 'Java' strains can be grown from seed. 'Spectra' offers a mix of flower colors and has leaves variegated with cream or white; bronze-leafed 'Java' is available in single or mixed colors. 'Tango', also seed grown, has bright orange blooms and bronze-green foliage.

SunPatiens strain is the result of a cross between New Guinea hybrids and a wild species. These are long-lived, free-blooming plants that can take full sun in all but the hottest areas. Flower colors range from pinks and reds through coral and orange and white. Three form-based series are offered: Compact (upright and bushy, to 23 feet tall and wide); Spreading (mounding growth to 23 feet tall and 3 feet wide); and Vigorous (vase-shaped, 34 feet tall and 3 feet wide).
