If the thought of carotenoid, anthocyanin and flavonol pigments conjures up visions of unfathomable beauty, then you’ll definitely want to make the hibiscus family of flowering plants an important part of your gardening experience. The carotenoids create the dazzling yellow, orange and red colors, while the less stable anthocyanins contribute a range of hues that span the blue, purple, pink, red, and black regions of the spectrum depending on variety and growth conditions. Finally, the flavonols cover the lighter range of colors spanning pale yellow to white. In response to temperature, season and soil conditions, the hibiscus flowers undergo a color metamorphosis as the composition and ratio of these pigments change.
