Versatile New Guinea Impatiens
What makes these impatiens so different is that they actually tolerate sun, although 6 hours a day is plenty. They also like to be slightly dry between waterings, another bonus for busy gardeners. The large blooms are up to 3 inches wide and range from pastels to hot electric pink, salmon, orange, and red. New Guinea impatiens will bloom until late August and are perfect in pots, hanging baskets, and borders. They are compact, bushy plants reaching 10 to 12 inches in height and width, with either solid green or variegated green-and-white leaves. The cultivars with the largest blooms have quickly become my favorites. Look for 'Paradise' and 'Pure Beauty' when shopping for New Guinea impatiens.
