Flowering plant: leave it to revert, surrounded by a lot of wood (7)
I believe the answer is:
godetia
'lot of wood' is the definition.
The definition suggests a singular noun which matches the answer.
'flowering plant leave it to revert surrounded by a' is the wordplay.
I cannot quite see how this works, but
'leave' could be 'go' (to go is to depart or leave) and 'go' is present in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found within the answer.
'a' is present in the answer.
The remaining letters 'dei' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for godetia that I've seen before include "Showy plant, I'd go eat (anag.)" , "Showy plant; got idea (anag.)" , "Garden flower" .)
