Sorry, but this is definitely not real. I'm including the best short article to explain why we see green, yellow, reds, sorta purples but not blue leaves. There is a plant that while the leaves are young produce a blue pigment (reflects blue light) to protect the new leaves from herbivores and there is ONE fern in the rain forest that is very blue. Cyanobacteria are blue but color varies with different colors of the light spectrum today. They were here 3.5 billion years ago and because of this bacteria, which is still a huge part of life on this planet now, we were able to be here. Otherwise, there would be no Oxygen in the atmosphere. These blue cyanobacteria changed our atmosphere completely, killing off the rest of life where Oxygen was toxic.
Cyanobacteria were the precursors of our green plants today. Chloroplasts evolved to do the photosynthesis necessary to make food and because of them, green light is reflected. Now we see green LEAVES (flowers don't photosynthesize).
This blue Japanese Maple is produced by either a filter on the camera or photo shopped, etc.
So definitely NOT TRUE! I did find Amazon was selling maple seeds which is a joke as there is no way to tell what that seed will turn out phenotypically or genetically. The samaras look dark and people will get fooled.
Great question. I had to actually pull up an old dusty stored in my brain about the light spectrum and what and why we see the colors we do get to see. Which is a very tiny, tiny part of the spectrum of light. blue plants and why
