No! Greenery (and landscapes in general) is pretty dark. That's why many people speak of "Sunny 11" instead of "Sunny 16". If you don't believe me, don't argue, just try with a light meter that allows both incident and reflected measurements. If the subject is a lanscape, the exposure from reflected measurement will be approx. 1 stop more than from incident (looking at light same as scene, i.e. opposite direction compared with reflected measurement).Green grass is pretty close to an 18 percent gray.
