The flower language of morning glory, what color is morning glory

1. Flower Language

The flower language of morning glory is everlasting honor and love. It also symbolizes the indomitable spirit. As a twining herb, its stem is relatively weak, but it grows upward resolutely and climbs to higher places. This never-give-up spirit is still touching. More importantly, it is an annual plant with a short life but higher aspirations.

2. Color

Morning glory comes in many colors, the most common ones are blue-purple and purple-red, in addition to pink and white. The cultivated varieties have even richer colors, including crimson, pink, bright red, pink and white, yellow, and cyan, etc. Since the flower contains anthocyanin, it changes color over time, so it is one color in the morning and another color at noon.

3. How to change color

1. Control the temperature: The anthocyanins contained in morning glory will be affected by the temperature, because controlling the temperature is one of the ways to change the color. However, the temperature cannot be too high or too low, as this will be detrimental to plant growth. It is usually appropriate to keep the temperature above 10°C.

2. Supplement nutrients: The color change of morning glory is also related to the metal ions in the soil. Fertilizers can be used to supplement specific metal ions, thereby achieving the effect of changing color. However, do not apply fertilizer excessively. Be sure to pay attention to the amount and usage to avoid fertilizer damage.

3. Adjust the pH: The content of anthocyanins is also closely related to the pH of the soil, but an environment that is too acidic or too alkaline is not conducive to plant growth, so it is necessary to adjust appropriately. Generally, watering with ferrous sulfate solution can acidify the soil and lower the pH.
