This species is very variable in habit and pubescence; 
in high alpine regions it has short rigid branches, while in 
cultivation the branches elongate and become slender and 
procumbent. The pubescence varies on the same plant, 
the flowering branches have the leaves villous-pubescent 
beneath, while the leaves of the sterile branches are often 
quite glabrous. Also in the preceding species the leaves 
of the sterile branches become sometimes glabrous and at 
the same time the glossy upper surface changes to dull 
bluish-green.
