Salad leaf could shoot up (6)
I believe the answer is:
rocket
This might be a double definition.
'salad' is the first definition.
(I know that rocket is a type of salad)
'shoot up' is the second definition.
(I've seen this before)
'leaf could' is the link.
I am not very happy about this link. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for rocket that I've seen before include "In salad it's prepared" , "Self-propelled firework or missile" , "Roasting" , "Salad plant - shoot up" , "Salad vegetable" .)
