I loved seeing these growing wild in Southern Utah, and the first year I planted it here in Northern Utah, it thrived in the sunlight with little water. The plumes were very floppy, though and often required staking.
It did not survive the winter, however. The soil might have been too heavy or too wet throughout the mild winter.
I have seen this plant growing in some very poor situations. Rocky soils, high alkalinity, full sun, and no additional water in the summer. I live in Farmington, NM and our annual precipitation is an average of only 10-12 inches a year. The last few years we have been in exteme draught conditions and this was one of the few wildflowers that came up and blossomed this year. The flower spikes can get pretty tall and the foliage is fairly attractive as well. I notice also that butterflies and bees like this plant.
This plant has been said to grow in the following regions:
Huntington, Arkansas Buhl, Idaho Las Vegas, Nevada West Valley City, Utah
