Ageratina shastensis is a species of snakeroot which is endemic to Shasta County, California. It is known by the common names Mt. Shasta snakeroot and Shasta eupatorium.[3][4][5]

Description

[edit]

Ageratina shastensis is a woody perennial which bears unassuming fluffy white flowers about a centimeter wide. It is an uncommon plant which grows in the cracks of limestone cliffs of the Mount Shasta, part of the Cascade Range.[6]

Etymology

Ageratina is derived from Greek meaning 'un-aging', in reference to the flowers keeping their color for a long time. This name was used by Dioscorides for a number of different plants.[7]
