Beaver resolved to consume new plant (7)
I believe the answer is:
verbena
'plant' is the definition.
The answer is an example.
'beaver resolved to consume new' is the wordplay.
'resolved' is an anagram indicator.
'to consume' indicates putting letters inside.
'new' becomes 'n'.
'beaver' with letters rearranged gives 'verbea'.
'verbea' enclosing 'n' is 'VERBENA'.
(Other definitions for verbena that I've seen before include "Ornamental plant with showy flowers" , "Garden plant" , "Herbaceous plant" , "Ornamental pant" , "Vervain (plant)" .)
