Plant life I’d removed from US state (5)
I believe the answer is:
flora
'plant life' is the definition.
(I've seen this before)
'i'd removed from us state' is the wordplay.
'removed from' indicates named letters should be taken away.
'us state' becomes 'florida' (I've seen this before).
'florida' with 'id' taken away is 'FLORA'.
(Other definitions for flora that I've seen before include "growing flowers" , "For example, Miss Macdonald" , "Botanical specimens" , "collection of plants" , "Plants collectively" .)
