Helping You Become a More Successful Gardener
Gerald L. Klingaman
This diverse genus of herbaceous plants holds some of the most popular bedding ornamentals on the market. Most impatiens are evergreen and of tropical and subtropical origin, with a few woodland species extending into north temperate regions. It is a huge genus with nearly 1000 species to its name and thousands of cultivated varieties. These may be annual or perennial, with many tropical perennial species grown as “annuals” in temperate zones.
The leaves and stems of impatiens are often fleshy and succulent and vary widely in color. There are two floral forms in this genus; the common garden form being a large flat-faced flower with five colorful, luminescent petals and the other being a tubular flower with a distinctive spurred nectary. Blooms come in a wide range of colors to include red, yellow, orange, pink, burgundy, salmon, white and purple-red, and all are followed by a bulbous green seedpod that explodes when squeezed.
The two most commonly grown impatiens are common impatiens (Impatiens walleriana) and the New Guinea hybrids (Impatiens hawkeri, I. schlechteri and I. platypetala crosses). The suite of species that comprise the New Guinea hybrids are known to have particularly colorful foliage of bronze, purple and various shades of green and large, colorful, flat-faced flowers. Common impatiens (Impatiens walleriana) are grown primarily for their beautiful flat-faced flowers. Both common and New Guinea impatiens will bloom continuously, if growing conditions are favorable, and do not require deadheading.
Overall, Impatiens prefer partial sun to shade and fertile, evenly moist soil with adequate drainage. They are ideal for shaded borders, containers and hanging baskets.
