Platform that is provided with small flowers (7)
I believe the answer is:
daisies
'flowers' is the definition.
(daisy is a kind of flower)
'platform that is provided with small' is the wordplay.
'platform' becomes 'dais' (dais is a kind of platform).
'that is' becomes 'ie' (abbreviation for id est, 'that is' in Latin).
'provided with' says to put letters next to each other.
'small' becomes 's' (abbreviation - e.g. clothes size).
'dais'+'ie'+'s'='DAISIES'
(Other definitions for daisies that I've seen before include "Asides I make to the flowers" , "Lawn flowers" , "Pushing up the --" , "Sis, idea about the little flowers" , "Flowers with yellow centres" .)
