Following Asian primate to test expertise in plants (9)

Ross

I believe the answer is:

floristry

I'm a little stuck... Click here to teach me more about this clue!

'expertise in plants' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'following asian primate to test' is the wordplay.
'following' becomes 'f' (used when citing page numbers etc).
'asian primate' becomes 'loris' (I've seen this in another clue).
'to test' becomes 'try' (synonyms).
'f'+'loris'+'try'='FLORISTRY'

Can you help me to learn more?

I've seen this clue in The Independent.
