Chimaphila umbellata (Umbellate Wintergreen, Pipsissewa, or Prince's pine) is a small perennial flowering plant found in dry woodlands, or sandy soils. It is native throughout the cool temperate Northern Hemisphere.
It grows 10–35 cm tall, and has evergreen shiny, bright green, toothed leaves arranged in opposite pairs or whorls of 3-4 along the stem. Leaves have a shallowly toothed margin, where the teeth have fine hairs at their ends. The flowers are white or pink, produced in a small umbel of 4-8 together.
Although it has green leaves year-round, it receives a significant portion of its nutrition from fungi in the soil (that is, it is a partial myco-heterotroph, which is not surprising as related plants, such as Pyrola, are partial or full myco-heterotrophs).<ref>Template:Cite journal</ref>
There are four subspecies:
- Chimaphila umbellata subsp. umbellata – Europe, Asia
- Chimaphila umbellata subsp. acuta – southwestern North America
- Chimaphila umbellata subsp. cisatlantica – northeastern North America
- Chimaphila umbellata subsp. occidentalis – northwestern North America
It is used as a flavoring in candy and soft drinks, particularly root beer.
"Pipsissewa" is a Cree name meaning "It-breaks-into-small-pieces".
