Flower, note, stemmed? (3,4)
I believe the answer is:
tea rose
'flower' is the definition.
(I've seen this before)
'note stemmed?' is the wordplay.
'note' becomes 'te' (musical note as in do re mi fa so la ti).
'stemmed?' becomes 'arose' (stem can mean to appear or arise).
'te'+'arose'='TEA-ROSE'
(Other definitions for tea rose that I've seen before include "Scented garden flower" , "Eats roe (anag.)" , "Flowering bush" , "Bloom" , "Garden plant" .)
