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 an anagram.
'stare' with letters rearranged gives 'ASTER'.
'can make you' acts as a link.
This may not be correct. Some or all of it may be part of 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" .)
