Redwood or dogwood
I believe the answer is:
tree
I believe this clue is a double definition.
'redwood' is the first definition.
(thesaurus)
'dogwood' is the second definition.
(thesaurus)
(Other definitions for tree that I've seen before include "Theme" , "A number" , "Hazel for instance" , "Chestnut or elm?" , "Shoe stretcher" .)
