But how did they meter? If the flora and earth/rock meter the same, then of course they blend in together. A red ball will pop out visually to the eye when sitting on green grass, but if they metter about the same, then in B&W the ball will not pop out visually on the film. Not really about panachromatic B&W film's responce to color, but the intensity of light reflected off the ball and the grass.
Now, the amount of light objects are reflecting might change due to the color balence of the light hitting them, but your meter will tell you that. Your brain is differentiating between the earth and the flora on the basis of color...but your film is differentiating between them based on the amount (not color) of light reflecting off of them.
In your example, you may wish to use a filter to seperate the values of the earth and the foliage -- green to lighten the flora relative to the brown earth...or an red/orange filter to darken the flora relative to the earth.
