Stare wildly at plant (5)
I believe the answer is:
aster
'plant' is the definition.
(aster is a kind of plant)
'stare wildly' is the wordplay.
'wildly' indicates anagramming the letters.
'stare' is an anagram of 'ASTER'.
'at' is the link.
(Other definitions for aster that I've seen before include "Kind of daisy" , "Stare (anag.)" , "Purple pink flowered plant" , "Flower of the daisy family - rates (anag)" , "Daisy-like garden flower" .)
