Charming father having energy for plant (8)
I believe the answer is:
sweetpea
'plant' is the definition.
The answer is an example.
'charming father having energy' is the wordplay.
'charming' becomes 'sweet' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'father' becomes 'pa' (pa can mean dad or father).
'having' means one lot of letters goes inside another.
'energy' becomes 'e' (physics symbol as in E=mcw).
'pa' enclosing 'e' is 'pea'.
'sweet'+'pea'='SWEETPEA'
'for' is the link.
Can you help me to learn more?
(Other definitions for sweetpea that I've seen before include "climbing plant" , "climber" .)
