Borders can be grand with seed scattered around (5)
I believe the answer is:
edges
'borders' is the definition.
('edge' can be a synonym of 'border')
'grand with seed scattered around' is the wordplay.
'grand' becomes 'g' ('G' can be a synonym of 'grand').
'with' is a charade indicator (letters next to each other).
'scattered around' indicates anagramming the letters (I've seen this in other clues).
'g'+'seed'='gseed'
'gseed' is an anagram of 'EDGES'.
'can be' is the link.
(Other definitions for edges that I've seen before include "Bounds" , "Borders, rims" , "They're used for cutting" , "Outside limits" , "Margins" .)
