A flower can make you stare wildly (5)
I believe the answer is:
aster
'a flower' is the definition.
(type of flower)
'stare wildly' is the wordplay.
'wildly' indicates anagramming the letters.
'stare' is an anagram of 'ASTER'.
'can make you' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for aster that I've seen before include "bloomer" , "eg Michaelmas daisy" , "Stare (anag.)" , "Garden plant" , "(Starlike) flower" .)
