Ageratum is a fascinating genus of flowering plants known for their often blue, fluffy flowers, although varieties with white, pink, or purple blooms also exist.
Understanding Ageratum
Ageratum plants are part of the large Asteraceae family, which also includes common plants like sunflowers, daisies, and chrysanthemums. This genus comprises approximately 40 to 60 species, primarily consisting of tropical and warm temperate annuals and perennials.
| Botanical Name | Common English Name (in the US) | Plant Type | Family | Origin |

| Ageratum | Whiteweed | Annuals & Perennials | Asteraceae | Tropical & Warm Temperate Regions |
These plants are widely cultivated for their ornamental value in gardens and as bedding plants. They are known for their long blooming season, often from spring until the first frost, providing continuous color.
Characteristics of Ageratum (Whiteweed)
- Appearance: Ageratum species typically produce clusters of small, fuzzy flowers. While commonly associated with a vibrant blue color, they also come in shades of white, pink, and purple. The term "whiteweed" specifically highlights the white-flowered varieties or perhaps a general impression of the plant in certain regions.
- Growth Habit: Depending on the species and cultivar, ageratum can range from low-growing, compact plants suitable for borders to taller varieties used as cut flowers.
- Geographic Distribution: Native to tropical and warm temperate regions, these plants thrive in full sun to partial shade and well-drained soil. They are widely grown as annuals in cooler climates due to their sensitivity to frost.
