Scattered snow about (4)
I believe the answer is:
sown
'scattered' is the definition.
(I've seen this in another clue)
'snow about' is the wordplay.
'about' is an anagram indicator.
'snow' anagrammed gives 'SOWN'.
(Other definitions for sown that I've seen before include "Placed in ground as seed" , "(Of seeds) planted" , "(Of seed) planted" , "set out to grow" , "Broadcast" .)
