Gardeners' Notes:

Central Phoenix -- Brittlebush is such an iconic Sonoran Desert flower. Mine grows in a bed raised 3 feet above the main yard level. It gets only natural precipitation. A palo blanco and nearby creosote give it a bit too much shade, but aside from getting taller and lankier, it still does well.

Saw this around Shoshone, Amargosa and Death Valley alot. Beautiful plant, much more heavily flowered when growing along roadsides due to runoff.

I've seen this growing in the wild in the South Mountian Preserve in Phoenix and surrounding Phoenix desert, and on the 'El Camino Del Diablo Trail' (Devils' Highway) that runs between Ajo and Wellton in Arizona through the Cabeza Prieta National Wildlife Refuge.

Do not over-water, or the plant will grow too quickly and crack under its own weight

Need to water well until established.Once established needs no watering.Does well in fertile well drained sandy soil.Remove the flower heads after bloom to enjoy the silvery foliage.Over watering will cause the plant to be more green than silvery.Cut back in fall or winter to encourage new growth.Blooms in spring but also blooms sporadically through the summer.
