Variety traits

Iris flower color

Iris L.

Iris color is a key ornamental trait determined by the distribution of anthocyanins and carotenoids. The standardized RHS color chart is used for its assessment.

In the reference 10 varieties crop Iris, where this is mentioned in the description.

The Royal Horticultural Society (RHS) color chart is used for an objective description of iris colors. Breeding programs distinguish several pigment distribution patterns: self, bitone, and amoena, where white standards are combined with colored falls. The contrasting color of the beard in bearded irises is also an important element.

Currently, the iris genotype lacks genes that provide for the expression of absolute black, bright red, or green coloration. Intense breeding for complex color combinations sometimes leads to a decrease in plant resistance to diseases and climatic factors, which requires the incorporation of wild species to restore vigor.
