What is the word for a plant covered in fine white hairs?

There are some plants whose leaves and stems are not the usual glossy green, but which are covered in very fine white hairs, or white fuzz. One example I have right now in my kitchen would be sage.

I am sure that there is a word in the English language which describes the appearance of such plants (not just fuzzy plants, but specifically ones covered in white fuzz). But I don't remember the word. Does someone know it?
