Plant that grows on rocks, trees etc (6)

Ross

I believe the answer is:

lichen

(Other definitions for lichen that I've seen before include "Crusty, tufty growth on trees and stones" , "Small plants found on tree-trunks and stones" , "Tiny plants found on rocks and trees" , "It grows on rocks and trees" , "Growth found on tree trunks and rocks" .)

I've seen this clue in The Telegraph.
