Plant Blindness

An excellent overview of the phenomenon - how people don't see plants - from Tuesday's Science Times.

We barely notice plants, can rarely identify them and find them incomparably inert. “Animals are much more vivid to the average person than plants are,” Dr. Raven said, “and some people aren’t even sure that plants are alive.”

*sigh* sadly, it's true. Although, in my experience, people do notice trees, and care a heck of a lot about garden flora.
