Plants adult donated to society (6)

I believe the answer is:

agaves

'plants' is the definition.
The answer is an example.

'adult donated to society' is the wordplay.
'adult' becomes 'a' (abbreviation).
'donated' becomes 'gave' (give can mean to donate).
'to society' becomes 's' (common abbreviation in names of organisations).
'a'+'gave'+'s'='AGAVES'

(Another definition for agaves that I've seen is " Spiky plants".)

I've seen this clue in The Independent.
