Why can Alliums have different colors?

Alliums can display different colors due to variations in their pigments, which include anthocyanins, carotenoids, and flavonoids. The specific combination and concentration of these pigments, influenced by genetic factors and environmental conditions, determine the color of the flowers. Additionally, hybridization and selective breeding have contributed to the wide range of colors seen in Allium species. Environmental factors such as soil pH and sunlight can also affect pigmentation, leading to further color diversity.
