Wild About Utah: The Glacier Lily

I find it difficult to leave my canyon home in northern Utah especially during April and May. Every day brings new bloom and bird song. On April 12, I returned from nine days in Georgia for a family event. I quickly retreated to the canyon where I found spring in full bloom—spring beauty, balsamroot, Indian potato, locoweed, violet and perhaps my favorite, the glacier lily. It often appears at the edge of receding snow banks.

Its delicate beauty is a favorite early season food of the grizzly bear. Bears “till” up the land, turning over chunks of soil to access their tasty bulb. Glacier National Park scientists have learned that this “tilling” has some important side effects. Areas with recent bear diggings have less plant diversity and higher nitrogen levels than undisturbed parts of the landscape. Without much competition from other plants, glacier lily bulbs can quickly regenerate, and these new lilies produce twice the usual number of seeds, thanks to the nitrogen rich soil.

After digging up glacier lilies, bears often leave the bulbs for a few days to wilt in the sun. This “cooks” them a bit making them sweeter and easier to digest. First Nations lore shows that early peoples learned to dry and cook glacier lily bulbs by copying the grizzly. Black bears relish the bulbs as well while elk and deer munch the foliage.

The Shoshone ate the corms fresh or with soup, and the dried bulbs were a popular trade item between tribes. The leaves are edible as well and the green seed pods taste like green beans when cooked. Medical applications include reducing fever, swelling, infection, and they were used as a contraceptive. The glacier lily was collected during the Lewis and Clark Expedition. Meriwether Lewis mentioned this species numerous times in his journal. This may be because he thought it could be used as a “botanical calendar” to help track the onset of spring.

 

Glacier lilies are very sensitive to disturbance and harvesting the corm will effectively kill the plant. Though native tribes practiced active management of them, their populations have been greatly reduced. It is better to leave collection to wildlife.

“The snow is melting. The grizzly bears that have been sleeping beneath the snow, suspended like seeds, will prowl the warm fields just beneath the snow, grazing on the delicious emerging lilies. Sometimes the yellow pollen gets caught on the fur and snouts of the great golden bears as they grub and push through the lily fields, pollinating other lilies in this manner. In this crude fashion, they are famers of a kind, nurturing and expanding one of the crops that first meets them each year. The lilies follow the snow, and the snow pulls back to reveal the bears, and the bears follow the Lilies. The script of life begins moving with enthusiasm once again,” Rick Bass, author, naturalist, activist.
