Unusual hues in irises, such as deep chocolate browns, true blacks, clear pinks, vibrant oranges, and dazzling greens, emerge through specific genetic combinations and selective breeding. For example, a deep velvety black iris results from a high concentration of anthocyanin pigments, while a bright orange iris may indicate the presence of carotenoids. These unique colors are often highly sought after by collectors and hybridizers.
The pursuit of these exceptional blooms has driven significant advancements in iris breeding, expanding the color palette and contributing to a richer understanding of iris genetics. Historically, certain colors held symbolic significance, enhancing their desirability. Moreover, the development of new colors expands the options for garden design and floral arrangements, adding visual interest and aesthetic appeal.
