Did you know
- The name Ageratum comes from the Greek 'a-geras' meaning 'non-aging,' because the flowers retain their color for an unusually long time.
- Floss Flower is one of the few true-blue annuals available, making it invaluable for blue color schemes in gardens.
- The fuzzy, pom-pom-like flower heads lack ray florets entirely, consisting only of disc florets with protruding styles.
- In traditional medicine in its native Mexico, it has been used to treat wounds, fevers, and as an insect repellent.
- It was named after William Houston, a Scottish botanist who collected plants in Central America in the 1730s.
