I came a cross a webpage http://myfolia.com/plants/745-american-wintergreen-gaultheria-procumbens with an interesting statement:"American wintergreen normally grows to a ground-cover habit with a max height of 5.85 inches (that's 15.0 cm metric)."
I wonder if the case of the metric value being a reasonable one is a matter of tongue-in-cheek writing or if it just worked out that way.
Of course, 3-digit precision for a plant height is silly. Jim
