Flower, one left in wind (6,4)

I believe the answer is:

easter lily

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

'flower' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'one left in wind' is the wordplay.
'one' becomes 'i' (Roman numeral).
'left' becomes 'l' (common abbreviation).
'in' is an insertion indicator.
'wind' becomes 'easterly' (easterly is a kind of wind).
'i'+'l'='il'
'il' going into 'easterly' is 'EASTER LILY'.

Can you help me to learn more?
