Why do hibiscus flowers change color? An analysis of the reasons
The hibiscus blooms brilliantly, and what is astonishing is that its flowers go through a color change process from white to pink and then to deep red, making it deeply loved by many people. So why do hibiscus flowers change color? Let's take a look together.
1. Temperature reasons
Hibiscus flowers change color because of temperature and nutrients. When the temperature of its growing environment rises or falls, its flower color changes accordingly. In the morning it is normally white, at noon when the temperature rises it turns pink, and in the afternoon at sunset it turns deep red. This is mainly because when the content of anthocyanin substances contained in the hibiscus flower increases, a chemical reaction occurs, and this chemical reaction is the main reason for the hibiscus flower's color change.
2. Different varieties
There are many varieties of hibiscus. With some varieties, as the growth time lengthens, the flower color also changes. For example, with the white-flowered hibiscus (Hibiscus mutabilis), in the first year the flower color is pink, and by the second year the flower color changes to bright red. With some varieties, however, the flower color does not change, such as the double-petaled hibiscus.
3. Different soil
Sometimes, when the soil used for planting is different, the flower color also changes. If acidic soil is used for planting at the beginning, then the flowers produced by some varieties will have a relatively lighter color. Later, during the care process, if some alkaline soil is added, then the color of the hibiscus flower will become a bit deeper.
4. Different work
With some varieties, the flower color is also different in the morning and in the evening. For example, the common drunken hibiscus (Hibiscus mutabilis 'Zui Furong') has red flowers in the early morning, but as evening approaches, its flower color changes to purple-red. This is because it has absorbed enough light, so the color also changes.
