Close-up of the calyx and corolla of granite gilia as seen at Antelope Mt. Lookout, Malheur National Forest..............July 18, 2010.
Granite gilia is an erect wildflower, shrub-like with several to many branches either in an open pattern or perhaps even densely packed. The plant is sweetly aromatic. The flowers seem to close or wrinkle up during daylight hours, and it is rare to see the whole plant in bloom, but such a find is a marvelous sight! (and a treat to the nose too!)
The plant may attain a height of 60 cm. Leaves are numerous and crowded on the stems. The lower leaves may be opposite, while those higher up may be alternate. The leaves are palmatified into 3 to 7 sharp, rigid, linear segments. The leaves are a dark green, and dead leaves may persist on the plant through several growing seasons.
The flowers are solitary in the leaf axils. The corolla is 15 to 25 mm long. Petal color ranges from creamy white to lavender, yellowish, or salmon. Granite Gilia is a nocturnal bloomer, so as mentioned above, it is rare to see it in full bloom during daylight hours.
Granite gilia is a plant of dry, open sandy, dusty, or rocky places. It is a plant of deserts, plains, and open forests to moderate elevations in the dry mountains of the west.
Granite gilia is found from southern British Columbia south along the eastern base of the Cascades to Baja California. It is found eastward to Montana, western Nebraska and Colorado, and New Mexico.
