Mistakes made with flowers (8)

I believe the answer is:
bloomers
'mistakes' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bloomers that I've seen before include "Undergarments popularised by Amelia" , "displayed in bed" , "Mistakes, underpants, loaves or flowers" , "Boobs" , "of bakers, gardeners and > underwear suppliers?" .)
