Presumably an English rose? (5)

I believe the answer is:

rhoda

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

'rose?' is the definition.
Both the answer and definition are singular nouns.
Maybe there's an association between them I don't understand?

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for rhoda that I've seen before include "Girl's name; hoard (anag.)" , "Woman" , "Girl" , "Fem. name; hoard (anag.)" .)

I've seen this clue in the Evening Standard.
