Ageratum Plant – Long lasting colorful plant

Last Updated on

Ageratum Plant – Also known as whiteweed and floss flower.  It is a big family of plants that have over 60 species.  They are considered an annual in regions where there are consistent freezes.  It is a good plant to use in containers surrounded by other taller plants. You can also place it in your flowering garden but should be used as a filler plant as it does not grow very tall, about 4 maybe 8 inches in height.

In and around the Southwest region the plant produces a nice round fluffy bluish color and will typically bloom from mid-spring until mid-fall.  The best time to plant is in early spring.
