Schoolmaster's bloomer? (5)
I believe the answer is:
aster
'bloomer?' is the definition.
(I know that aster is a type of bloomer)
'schoolmaster's' is the wordplay.
'ASTER' is hidden within the letters.
However, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for aster that I've seen before include "Purple pink flowered plant" , "Plant of Michaelmas daisy family" , "Flowering plant; tares (anag.)" , "Flower of the daisy family - rates (anag)" , "eg Michaelmas daisy" .)
