Utah, some blooming continues from June to October or until time of frost. There is 

 usually a heavy first blooming that produces more than 90 percent of the annual seed 

 crop. Heavy summer storms can stimulate additional blooming resulting in considerable 

 seed production. However, we have never observed a later seed crop as productive as 

 that of the first blooming. 



Ants, hornets, and bees have been observed on Apache plume flowers. We suspect 

 these insects are important factors in the cross-pollination of Apache plume. 



Eyhvidization: During the years 1967-70, some of the pistillate flowers on shrubs 

 located at North Willow Creek Canyon, about 2 miles^northwest of Richfield, Sevier
