'seasonal flower' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'i left in wind' is the wordplay.
'left' becomes 'l' (common abbreviation).
'in' indicates putting letters inside.
'wind' becomes 'easterly' (easterly is a kind of wind).
'i'+'l'='il'
'il' placed into 'easterly' is 'EASTER LILY'.
