Why Are Some Plants Blue?
Plants are predominantly green, so it is out of the norm to find one with blue leaves or stems.
Essentially, some plants are blue so that they are in a better position to absorb the light required for photosynthesis.
This is especially so when they are growing in a shady area.
In some plants like the Begonia pavonina, the chloroplasts, which are responsible for light absorption, are arranged in stacks to form crystals.
Normally, chloroplasts have a random arrangement inside the leaf of a plant.
The photonic crystals in Begonia pavonina give the leaves of the plant a blue hue.
When a plant has a blue leaf, it mainly absorbs green and red light frequencies. In essence, it absorbs more light energy than plants with green leaves.
