Features
The number one selling bedding plant offering bold dependable color all summer long in shaded areas. New Guinea impatiens (Impatiens hawkeri) offer the addition of colorful foliage to go along with larger, more colorful flowers and can also be used in areas receiving more sun. 
 
Culture
Impatiens do best in shade, with the exception of the New Guinea type that tolerates and does better in areas receiving partial sun. All benefit from at least afternoon shade. Soils that retain moisture is beneficial to maintaining quality. Good drainage is important for New Guinea types.
