Flower out of bed — nothing raised around it (5)
I believe the answer is:
lupin
'flower' is the definition.
(I've seen this before)
'out of bed nothing raised around it' is the wordplay.
'out of bed' becomes 'up' (synonyms).
'nothing' becomes 'nil' (eg nil is zero in football).
'raised' is a reversal indicator (going up in a down clue).
'around it' means one lot of letters goes inside another.
'nil' back-to-front is 'lin'.
'up' going within 'lin' is 'LUPIN'.
(Other definitions for lupin that I've seen before include "Plant with flowers on long spikes" , "Spiked flower" , "9 [BLOOM]" , "bloomer" , "Fodder plant" .)
