I have never seen that, and there is still a possible physical
explanation! It is a moderately drought-resistant plant, and could
well be good at extracting water. B. darwinii, at least, isn't as
nearly as drought-resistant as its leaves would imply.

From a gardener's point of view, there is little difference.
