christmas tree

I'm a little stuck... Click here to teach me more about this clue!

'seasonal growth' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.

'miser chatters about' is the wordplay.
'about' is an anagram indicator.
'miser'+'chatters'='miserchatters'
'miserchatters' is an anagram of 'CHRISTMAS-TREE'.

Can you help me to learn more?
