Fast Fact

Due to the chemical structure of chlorophyll and the process of photosynthesis, there is no such thing as a blue flower. Photosynthesis works by absorbing sunlight and converting it into energy for the plant to use. Since chlorophyll is able to convert blue light much better than the rest of the visible spectrum, plants don’t reflect that light (as it is all converted); hence, no blue flowers. Most “blue” flowers are actually a shade of purple. For all you greenthumbs out there, this means growing your plants under blue lights will increase their size and health.
