Per Jan Emming owner of the Destination:Forever Ranch and Gardens, a 40 acre desert botanical garden and sustainable living homestead in the Arizona desert with a nursery:

One of the most striking plants in bloom in the Four Corners and Colorado Plateau in the months of May and June is the Prince's plume (Stanleya pinnata), a large and conspicuous member of the mustard family. Parts of the Navajo Nation were covered in a singular mass display of these, a thing which I have never seen before since these plants tend to exist more as scattered individuals rather than as carpets. These scenes were captured along McElmo Creek in southwestern Colorado, which flows to the north of Ute Mountain and westwards from Cortez to the San Juan River. It had rained the night before, and the ... read more

It did not survive the winter, however. The soil might have been too heavy or too wet throughout the mild winter.

Slender stalks of yellow flowers atop tall, stout, smooth bluish-green, leafy stems.

Found in deserts and plains to lower mountains, often in sagebrush, from southeastern OR, to southeastern CA, east to the Great Plains from ND to west TX.

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.
