In IPA, Ageratina is spelled /ədʒəˈreɪtnə/ and Altissima is spelled /ælˈtɪsimə/. These spellings help ensure accuracy in pronunciation and communication about the plant.

Ageratina altissima, commonly known as white snakeroot, is a perennial herbaceous plant native to eastern and central North America. It belongs to the aster family (Asteraceae) and is characterized by its white flowers and toothed leaves. White snakeroot typically grows to a height of 1 to 3 feet (30 to 90 centimeters) and is found in shady woodland areas, along stream banks, and in open meadows.
The leaves of Ageratina altissima are simple, opposite, and heart-shaped with serrated edges. The plant produces small, white flowers in clusters, forming dense inflorescences at the tops of the stems. The inflorescences are made up of numerous individual flowers, each with five petals, giving them a dainty appearance. The flowering period typically occurs from mid-summer to early fall.
While white snakeroot possesses aesthetic qualities, it is important to note that the plant contains compounds that can be toxic to livestock and humans. The toxic substance, called tremetol, can be transmitted through the consumption of contaminated milk or meat from animals that have grazed on white snakeroot. This has been known to cause a condition called milk sickness, which can be fatal if not properly treated.
In conclusion, Ageratina altissima refers to a herbaceous perennial plant native to eastern and central North America. It is characterized by white flowers, toothed leaves, and a potential toxicity to livestock and humans if ingested.
