| Description | A dominant member of low desert plant communities in western Arizona. In some of the hottest parts of the Sonoran Desert where trees are scarce, white bursage serves as an important "nurse plant" for saguaros (Carnegia gigantea) as they germinate and begin to grow. Plant on well draining soils or mounds in combination with creosote (Larrea tridentata), burrobush (Hymenoclea salsola), and globe mallow (Sphaeralcea ambigua) in a problem spot where other plants fry in the heat. Of all the bursages this species may have the showiest bloom with its spikes of shaggy yellow flowers. |
