It springs up in the centre, especially (4)

I believe the answer is:

tree

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

'it springs up' is the definition.
The definition suggests a singular noun which matches the answer.

'in the centre especially' is the wordplay.
'in' says the answer is hidden in the clue.
'TREE' is hidden within 'centre especially'.

Can you help me to learn more?

(Other definitions for tree that I've seen before include "Branching diagram" , "Large, woody perennial plant" , "Eg, elm or oak" , "Eg, alder" , "A number" .)

I've seen this clue in the Evening Standard.
