Bloomers causing wild stares? (6)
I believe the answer is:
asters
'bloomers' is the definition.
(type of flowering plant)
'wild stares?' is the wordplay.
'wild' indicates anagramming the letters.
'stares' anagrammed gives 'ASTERS'.
'causing' is the link.
(Other definitions for asters that I've seen before include "Stares at bright flowers" , "Daisylike flowers" , "Stares oddly at the flowers" , "Stares around at the flowers" , "Otherwise known as Michaelmas daisies" .)
