Deliver, as I arranged, the plant (7)
I believe the answer is:
freesia
'plant' is the definition.
The answer is an example.
'deliver as i arranged' is the wordplay.
'deliver' becomes 'free' (I've seen this before).
'arranged' indicates an anagram (letters rearranged).
'as'+'i'='asi'
'asi' with letters rearranged gives 'sia'.
'free'+'sia'='FREESIA'
'the' is the link.
(Other definitions for freesia that I've seen before include "Fragrant flower (sounds rather cold?)" , "Highly scented flower" , "Plant of the iris genus" , "bloomer" , "Fragrant-flowered plant; faeries (anag.)" .)
