Reagan is irritated about Democrat presenting the Bushes (9)

I believe the answer is:

gardenias

'the bushes' is the definition.
(gardenia is a kind of bush)

'reagan is irritated about democrat' is the wordplay.
'irritated' is an anagram indicator (I've seen this in other clues).
'about' means one lot of letters goes inside another.
'democrat' becomes 'd'.
'reagan'+'is'='reaganis'
'reaganis' with letters rearranged gives 'garenias'.
'garenias' enclosing 'd' is 'GARDENIAS'.

'presenting' acts as a link.

I've seen this clue in The Telegraph.
