I care about a growing girl (5)

I believe the answer is:

erica

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

'a growing girl' is the definition.
'Erica' can be an answer for 'girl'. I am not sure about the 'a growing' bit.

'i care about' is the wordplay.
'about' is an anagram indicator.
'i'+'care'='icare'
'icare' anagrammed gives 'ERICA'.

Can you help me to learn more?

(Other definitions for erica that I've seen before include "Shrub genus; girl's name" , "I care about Heather, oddly" , "I care (anag) - plant - girl" , "Plant genus of garden heather" , "Girl's name - I care (anag)" .)

I've seen this clue in The Globe and Mail.
