Why are there different colors of lupines?

Different colors of lupines are primarily due to variations in pigments produced in their flowers, such as anthocyanins and flavonoids. These pigments can create a range of hues, including blue, purple, pink, and white. Additionally, selective breeding and genetic diversity within lupine species contribute to the variety of colors observed in cultivated and wild populations. Environmental factors may also influence pigmentation, resulting in subtle differences in color.
