This big leafy plant was growing quite tall, about to my hip, near the stream bed. Its stem was a light green, and smooth. It seemed that each stalk was growing individually out of the ground, and produced only one giant leaf. It was much larger than any coltsfoot I have ever seen before, and it was without flower.
Dominant groundcover in Ponderosa overstory campgrounds, not sure if arctic or western.
Palmates coltsfoot according to Dr. Pojar, seen in the densely wooded area approaching the Toutle River Sediment Retention Dam off Spirit Lake Highway.
The plants commonly referred to as Butterbur are found in the daisy family Asteraceae in the genus Petasites. They are mostly quite robust plants with thick, creeping underground rhizomes and large Rhubarb-like leaves during the growing season. Another common name for many species of this genus is Sweet Coltsfoot.
