Queen’s Cup

CAN BE FOUND IN:

Queen's Cup

Clintonia uniflora 

Apearance

Large lance-shaped basal leaves (leaves close to the ground) surround the skinny stalk, which holds the small one-inch star-shaped white flower. 

Range & Habitat

These flowers like the shaded habitat of the forest floor the most, but are also seen along rivers and streams which are thick with brush. Their northern limit is the Yukon and can be seen as far south as California. Their boundary to the east is the Cascade Mountains in Washington. 

reciprocal Relationships

The Queen’s cup is an important species in B.C. It is a small plant, but its presence can help us learn a lot about the ecosystem. When a queen’s cup is found growing in an area, it often means that grand firs are less likely to die from fir engraver beetles.

This plant has beautiful star-shaped white flowers that appear from late May to July. After the blooming period, a single blue berry appears on top of the slender stalk, which is poisonous to humans.  

While they are poisonous to humans, ruffed grouse love to munch on the berries of this plant when they are ripe in the fall. Instead of eating this plant, the blue berries are crushed and used by the Lower Nlaka’pmx as a blue dye. The leaves are used by the Lil’wet’ul and the Okanagan for eye infections and to stop bleeding. 

Status

COSEWIC: Not Reported
