Oreomecon pygmaea is a species of poppy known by the common name alpine glacier poppy. It is native to North America, where it can be found in British Columbia, Alberta, and Montana. It has a narrow distribution around the intersection of the three borders. There are about 44 known occurrences, mostly in Montana, with about a third in Alberta and two in British Columbia.[1] It is present in a number of locations within Glacier National Park.[3]
This perennial herb produces a stem up to 12 centimeters tall from a taproot. The blue-green leaves are up to 5 centimeters long. The flower is about 2 centimeters wide. The petals are yellow, orange-pink, or orange with a yellow spot. The fruit is a rough-haired capsule about 1.5 centimeters long.[4] Blooming occurs in July and August.[3]
This plant grows in high mountain habitat in alpine climates. It grows on rocky terrain such as talus and fell fields.[3]
