Flower in centre of Beijing adorning bedcover, detailed (7)
I believe the answer is:
jonquil
'flower' is the definition.
(I've seen this before)
'centre of beijing adorning bedcover detailed' is the wordplay.
'centre of' means to look at the middle letters.
'adorning' becomes 'on' (I am not sure about this - if you are sure you should believe this answer much more).
'bedcover' becomes 'quilt' (I've seen this before).
'detailed' means to remove the last letter (the word must be end-less or 'de-tailed').
The middle of 'beijing' is 'j'.
'quilt' with its last letter taken away is 'quil'.
'j'+'on'+'quil'='JONQUIL'
'in' is the link.
Can you help me to learn more?
(Other definitions for jonquil that I've seen before include "Species of narcissus" , "Kind of narcissus (but not in fact a daffodil!)" , "Flowering plant" , "Flower" , "Name used colloquially for any yellow daffodil" .)
