Daisy's Easter contribution (5)

I believe the answer is:

aster

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

'daisy's' is the definition.
(I've seen this before)

'easter contribution' is the wordplay.
'ASTER' is hidden within the letters.
But, I'm unsure how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for aster that I've seen before include "Tears about bright flower" , "It grows" , "Flower of the daisy family - rates (anag)" , "Tears (anag) - plant" , "Daisy-like plant" .)

I've seen this clue in the Evening Standard.
