Postponed gardener finally dividing exposed tall climbing honeysuckle (8)

'honeysuckle' is the definition.
(I've seen this before)

'postponed gardener finally dividing exposed tall climbing' is the wordplay.
'postponed' becomes 'onice' (I've seen this in another clue).
'finally' indicates one should take the final letters.
'dividing' means one lot of letters goes inside another (inserted letters divide the word).
'exposed' means to look at the middle letters (outside letters removed).
'climbing' says the letters should be written in reverse (in a down clue, letters climb up).
The middle of 'tall' is 'al'.
The last letter of 'gardener' is 'r'.
'al' in reverse letter order is 'la'.
'onice'+'r'='onicer'
'onicer' inserted into 'la' is 'LONICERA'.
