Daisy's kin (5)
I believe the answer is:
aster
'daisy's kin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aster that I've seen before include "Plant of Michaelmas daisy family" , "Flowering plant; tares (anag.)" , "Kind of daisy" , "(Starlike) flower" , "Daisy-like garden flower" .)
