An odd girl makes a bloomer (4,4)

I believe the answer is:

arum lily

'a bloomer' is the definition.
(arum lily is a kind of flowering plant)

'an odd girl' is the wordplay.
'an' becomes 'a'.
'odd' becomes 'rum' (I've seen this before).
'girl' becomes 'lily' (I've seen this before**).
'a'+'rum'+'lily'='ARUM LILY'

'makes' is the link.

(Another definition for arum lily that I've seen is " plant".)

I've seen this clue in The Telegraph.
