*ghre:- "to grow"

 To grow, become green. Contracted from *ghreH1-. 1. O-grade form *ghr-. grow, from Old English grwan, to grow, from Germanic *gr(w)an. 2. Suffixed o-grade form *ghro:-n-yo-. green, from Old English grne, green, from Germanic *gro:njaz, green. 3. Suffixed zero-grade form *ghr&-so-. grass, graze¹, from Old English graes, grass, from Germanic *grasam, grass. (Pokorny (ghr-) 454.)

 

Is there any example of this root outside Germanic?

Perhaps Greek khronos "time" ?
