Examples of Blue House Plants

Imagine a world in which the oceans are filled with purple algae, and forests are swaying in blue-colored leaves. Of course we’re not talking about something from a science-fiction book, either.

It is a common belief that all life forms must be green. This is due to the fact that plants produce energy through chloroplasts. Chloroplasts comprise chlorophyll and chlorophyll is green.

Begonia pavonina, also known as Peacock Begonia, Sedum Blue Pearl, Silver Sword Philodendron, Blue Agave, Blue Hosta, Crassula Ovata Blue bird’ as well as Cebu Blue Pothos are all examples of blue leaf houseplants. The blue leaf is due to special photonic crystals that are able to more efficiently absorb solar energy.

The results of research show that the first photosynthesis organisms were violet because they utilized photosynthetic chemicals that absorb light at various wavelengths.

What Causes Blue Leaves on Plants?

The Begonia pavonina, also known as peacock begonia, usually has vibrant blue leaves in addition to the more typical green leaves.

Scientists at Bristol University University of Bristol wrote in Nature Plants ( Source) that the begonia required blue leaves as they better absorb the light required to produce photosynthesis. This is particularly important in the case of B. pavonina that grows in the shade of the trees of Malaysian forests.

It is known that plant cells absorb sunlight through organs within their cells, which are known as chloroplasts.

These tiny organelles, referred to as chloroplasts, are the places plants keep their chlorophyll.

In the begonia B. pavonina, the chlorophyll stacks do not appear randomly , as in other plants, but instead form photonic crystals.

The blue hue of the leaves of begonia pavonina is due to the photonic crystals. The most important aspect is the fact that chlorophyll of this type is better able to absorb the red and green light frequencies.

Thus, B. pavonina receives 10 percent more energy than its peers, which aids them in growing in the lower forests floors.
