Stare wildly at bloom (5)
I believe the answer is:
aster
'bloom' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Maybe there's a link between them I don't understand?
'stare wildly' is the wordplay.
'wildly' indicates an anagram.
'stare' anagrammed gives 'ASTER'.
'at' is the link.
Can you help me to learn more?
(Other definitions for aster that I've seen before include "Daisy-like plant" , "Tears (anag) - plant" , "Purple pink flowered plant" , "Stare oddly at the flower" , "Flowering plant; tares (anag.)" .)
