Parking on verge, went up for flower (8)
I believe the answer is:
primrose
'for flower' is the definition.
(I've seen this before)
'parking on verge went up' is the wordplay.
'parking' becomes 'p' (abbreviation on road signs).
'on' says to put letters next to each other.
'verge' becomes 'rim' (both can mean an edge).
'went up' becomes 'rose' (I've seen this in another clue).
'p'+'rim'+'rose'='PRIMROSE'
(Other definitions for primrose that I've seen before include "Pale yellow- a primula" , "Woodland plant with pale yellow flowers" , "something in the bed!" , "Yellowish" , "Wild flower (connected to an attractive path?)" .)
