Impatiens New Guinea Group

New Guinea hybrids

New Guinea Group Impatiens are hybrids of Impatiens plants with a great variety of flower and leaf colours and are sold in nurseries and garden centres for summer bedding and patio plants. The species 'hawkeri' has often been crossed with Impatiens aurantiaca and Impatiens platypetala to improve characteristics such as drought resistance and floriferousness and to increase the colour range and improve the habit and compactness of plants.
