Daisy relative (5)
I believe the answer is:
aster
'daisy relative' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aster that I've seen before include "eg Michaelmas daisy" , "bloomer" , "Stare at pretty flower" , "Garden plant" , "Michaelmas daisy genus" .)
