Pigment Distribution
Variegation in Impatiens hawkeri arises from the uneven distribution of pigments within leaf tissues. Chlorophyll, responsible for the green color, may be partially or completely absent in certain areas, revealing underlying pigments such as carotenoids (yellow, orange) or anthocyanins (red, purple). This uneven distribution results in patterns ranging from subtle marbling to distinct sectors of contrasting colors. The specific pattern of variegation is genetically determined and can vary significantly between cultivars.
-
Common Variegation Patterns
Several distinct variegation patterns are observed in New Guinea impatiens. These include marginal variegation, where a contrasting color outlines the leaf edge; central variegation, with the contrasting color concentrated in the center of the leaf; and splashed variegation, characterized by irregular patches of contrasting color across the leaf surface. Cultivars like ‘Celebration Fusion Glow’ exhibit striking variegated patterns that complement their vibrant flower colors.
-
Influence of Environmental Factors
Environmental factors, such as light intensity and temperature, can influence the expression of variegation. In some cultivars, higher light levels may intensify the contrasting colors, while lower temperatures might enhance the expression of anthocyanin pigments, leading to more pronounced red or purple hues in the variegated areas. Understanding these influences allows gardeners to optimize growing conditions for desired variegation effects.
-
Interaction with Flower Color
The combination of variegated foliage and flower color is a key consideration in garden design. The contrasting colors of the leaves can either complement or contrast with the flower colors, creating diverse visual effects.
