Here's a tip: cultivate white wood aster (1,4,2,3,4)

Ross

I believe the answer is:

a word to the wise

'here's a tip' is the definition.

'cultivate white wood aster' is the wordplay.
'cultivate' indicates anagramming the letters (I've seen 'cultivated' mean this).
'white'+'wood'+'aster'='whitewoodaster'
'whitewoodaster' is an anagram of 'A WORD TO THE WISE'.

(Another definition for a word to the wise that I've seen is " some advice".)

I've seen this clue in The Everyman puzzle in The Observer.
