Rubbish is said about English flowers (7)
I believe the answer is:
daisies
'flowers' is the definition.
(daisy is a kind of flower)
'rubbish is said about english' is the wordplay.
'rubbish' indicates anagramming the letters (a poor quality or rubbish spelling of the letters).
'about' is an insertion indicator.
'english' becomes 'e' (abbreviation).
'is'+'said'='issaid'
'issaid' with letters rearranged gives 'daisis'.
'daisis' placed around 'e' is 'DAISIES'.
(Other definitions for daisies that I've seen before include "Sadie is wild about these flowers" , "As I side with the flowers" , "Flowers with yellow centres" , "Small grassland flowers" , "Asides I address to the flowers" .)
