'Flower' in the Bible

I am a rose of Sharon, a flower of the valleys.

As the lily-flower among the thorns of the waste, so is my love among the daughters.

I went down into the garden of nuts to see the green plants of the valley, and to see if the vine was in bud, and the pomegranate-trees were in flower.

Let us go out early to the vine-gardens; let us see if the vine is in bud, if it has put out its young fruit, and the pomegranate is in flower. There I will give you my love.
