I follow after father leaves (6)

Ross

I believe the answer is:

frisee

'leaves' is the definition.
(leafy plant)

'i follow after father' is the wordplay.
'follow' becomes 'see' (both can mean to understand).
'after' says to put letters next to each other.
'father' becomes 'fr' (abbreviation as in a priest's title).
'i'+'see'='isee'
'isee' put after 'fr' is 'FRISEE'.

I've seen this clue in The Telegraph.
