Characteristics:

The grass widows are beautiful early spring wildflowers. Frequently, they are among the first native flowers to bloom. It forms clusters of grass-like leaves which are shorter than the stems. The flower stems arise from 15-40 cm high, and are topped by 3-4 pale purple, blue, pink or white flowers. The petals are narrow and pointed. The stamens are yellow and the filament tube is strongly inflated just above its base (see photos above and below). They differ from their cousin Olsynium douglasii in having the inflated filament and pointed tips to the petals.

They may be found blooming in the Columbia River Gorge throughout March. Frequently, they paint the landscape purple with their massed bloom.


Habitat:

This grass widow is found in dry open areas which are seasonally wet during the early spring. It may be bound in grassy areas in the sagebrush or sagebrush-juniper lowlands, within grasslands, and within open areas in the ponderosa pine forest.


Range:

Olsynium inflatum may be found on the east side of the Cascade Mts. from south-central British Columbia south to California, and east to Idaho and northern Utah.

In the Columbia River Gorge, it may be found at the crest of the Columbia Hills north of the Dallesport, WA..
