Plant nuts and a beer (10)

I believe the answer is:

cuckoopint

'plant' is the definition.
(cuckoopint is a kind of plant)

'nuts and a beer' is the wordplay.
'nuts' becomes 'cuckoo' (I've seen this before).
'and' says to put letters next to each other.
'a beer' becomes 'pint' (beer is typically served by the pint).
'cuckoo'+'pint'='CUCKOOPINT'

I've seen this clue in the Sydney Morning Herald.
