Shrub sprang up (4)
I believe the answer is:
rose
I believe this is a double definition.
'shrub' is the first definition.
(rose is a kind of shrub)
'sprang up' is the second definition.
(I've seen this before)
(Other definitions for rose that I've seen before include "''That which we call a ..., by any other name would smell as sweet'' (Romeo and Juliet)" , "vacated bed" , "Prickly garden plant" , "Wine colour; plant" , "came up" .)
