Ageratum (also known as Floss Flower) flowers have hundreds of soft tiny cushions suffused with color. Spent flowers will fall to the ground as they fade to be replaced by new bloom throughout the growing season. Prompt deadheading of the faded flowers is not necessary, but keeps a planting tidy and tends to promote a better uninterrupted bloom. Charming in borders and showy in drifts. First autumn frost will kill most if not all plants, at which point they may be removed from the garden.
