Are staggering around the street making a bloomer (5)
I believe the answer is:
aster
'a bloomer' is the definition.
(aster is a kind of flowering plant)
'are staggering around the street' is the wordplay.
'staggering' indicates anagramming the letters (letters stagger around).
'around' is an insertion indicator.
'the street' becomes 'st' (abbreviation).
'are' anagrammed gives 'aer'.
'aer' going around 'st' is 'ASTER'.
'making' is the link.
(Other definitions for aster that I've seen before include "It grows" , "Tears (anag) - plant" , "Kind of daisy" , "Tears about bright flower" , "Purple pink flowered plant" .)
