Carl Linnaeus spent the 18th Century like an enchanted child, pointing at and naming (in Latin) all the life forms that he found. His own child, Elizabeth, noticed that when she looked at nasturtium flowers in the evening they seemed to flash. Research by different scientists of the day into the incident proposed different conclusions including electricity, phosphorescence, and the paranormal. Carl and his budding botanist daughter seemed content to dub it the Elizabeth Linnaeus Phenomenon and leave it at that. You may have a similar experience with these gleaming blooms, but not to worry, you are not being hauntedâitâs probably simply an optical illusion cased by the interaction of green and orange in the pale light of dusk.
