Foolish coming up with question, girl in plant (6,4)
I believe the answer is:
damask rose
'plant' is the definition.
The answer is an example.
'foolish coming up with question girl in' is the wordplay.
'foolish' becomes 'mad' ('mad' can be similar in meaning to 'foolish').
'coming up' says the letters should be written in reverse.
'with' means one lot of letters go next to another.
'question' becomes 'ask'.
'girl in' becomes 'rose' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'mad' in reverse letter order is 'dam'.
'dam'+'ask'+'rose'='DAMASK ROSE'
Can you help me to learn more?
(Other definitions for damask rose that I've seen before include "Sweet-scented flower yielding attar" , "bloomer" , "source of attar" , "hardy flower" .)
