     Breezes blowing from beds of iris quickened her breath with their perfume; she saw the tufted lilacs sway in the wind, and the streamers of mauve-tinted wistaria swinging, all a-glisten with golden bees; she saw a crimson cardinal winging through the foliage, and amorous tanagers flashing like scarlet flames athwart the pines.

2. A flower of the lilac shrub.
3. (color) A pale purple color, the color of some lilac flowers.
