Bloomer from bloke on bike perhaps confusing whereabouts of AE (8)
I believe the answer is:
cyclamen
'bloomer' is the definition.
(cyclamen is a kind of flowering plant)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for cyclamen that I've seen before include "Flower giving its name to a shade of pink" , "Garden flower" , "Perennial" , "Common house/garden plant" , "Plant with turned-back petals" .)
