A number try out the French shrubs (7)

I believe the answer is:

myrtles

'shrubs' is the definition.
(myrtle is a kind of shrub)

'a number try out the french' is the wordplay.
'a number' becomes 'm' (M is an example).
'out' indicates an anagram (out can mean wrong or inaccurate).
'the french' becomes 'les' (plural form of 'the' in French).
'try' is an anagram of 'yrt'.
'm'+'yrt'+'les'='MYRTLES'

(Another definition for myrtles that I've seen is " Sly term for the evergreen shrubs?".)

I've seen this clue in The Globe and Mail.
