Man on Later playing purely to show off? (10)

I believe the answer is:

ornamental

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

'purely to show off?' is the definition.
I can't judge whether this defines the answer.

'man on later playing' is the wordplay.
'playing' indicates an anagram.
'man'+'on'+'later'='manonlater'
'manonlater' with letters rearranged gives 'ORNAMENTAL'.

Can you help me to learn more?

(Other definitions for ornamental that I've seen before include "Fancy" , "Decorative" , "Plant grown for attractive appearance" , "showy" , "non-functional" .)

I've seen this clue in The Independent.
