Description

Distribution

Ecology

Habitat

Phenology

Seed dispersal

It disseminates its mature seeds (achenes) in fall and winter. Each plant can produce thousands of seeds at a time. [1]

Seed bank and germination

Ageratina altissima usually needs light to germinate. Ageratina altissima exhibits a Type II response to stratification: Germination in the spring generally can occur at a lower temperature than germination in the fall as a result of dormancy loss in the winter. Thus, germination in the spring is more likely because of relatively higher temperatures and lower temperature requirements than in fall. [2]

Fire ecology

It is most abundant after a late-season (early October) burn. [3]

Pollination

Use by animals

Diseases and parasites

Conservation and Management

Cultivation and restoration
