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

'self-absorbed youth' is the definition.
'narcissus' can be an answer for 'youth' (I have seen 'Beautiful youth' mean 'narcissus' so perhaps 'youth' could also mean 'narcissus'). I'm unsure of the 'self-absorbed' bit.

'neglected russians getting cold' is the wordplay.
'neglected' indicates anagramming the letters (allowed to grow wild, as a garden).
'getting' is an insertion indicator.
'cold' becomes 'c' (eg on taps).
'russians' is an anagram of 'narissus'.
'narissus' placed around 'c' is 'NARCISSUS'.
