Flower sprang up by soft verge (8)
I believe the answer is:
primrose
'flower' is the definition.
(I've seen this before)
'sprang up by soft verge' is the wordplay.
'sprang up' becomes 'rose' (rise can mean to spring up).
'by' is a charade indicator (letters next to each other).
'soft' becomes 'p' (musical abbreviation for 'piano').
'verge' becomes 'rim' (both can mean an edge).
'p'+'rim'='prim'
'rose' put after 'prim' is 'PRIMROSE'.
(Other definitions for primrose that I've seen before include "Yellowish" , "Wild flower (connected to an attractive path?)" , "Rip morse up to find the flower" , "something in the bed!" , "Spring woodland flower" .)
