Eros trampled flower (4)

I believe the answer is:

rose

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

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

'eros trampled' is the wordplay.
'eros' can be anagrammed to 'ROSE'.
However, I'm not clear how the anagram is indicated.

Can you help me to learn more?

(Other definitions for rose that I've seen before include "Flower - climbed" , "Garden flower" , "Flower; went upwards" , "grew" , "Thorny flowering plant" .)

I've seen this clue in The Mirror.
