Distinctive tan and blue-green linear leaves create a unique profile for this gorgeous desert tree.

Smoke Tree (Psorothamnus spinosus) A.k.a. Smokethorn, Smokethorn Dalea, and Corona de Cristo in Spanish. Native, perennial, thorny, glandular, desert legume tree that grows in Colorado Desert washes. Water and sand scouring is required for the seeds to germinate. Stems are gray-canescent and generally leafless, making the very-much-alive tree, appear dead. Flowers are indigo-blue. Peak bloom time: May-July.

Coachella Valley Preserve: For thousands of years, particles of sand from the San Bernardino Mountains and Indio Hills washed into the Coachella Valley forming a system of sand dunes. Today, these dunes are part of the Coachella Valley Preserve System, a 20,000-acre sanctuary.
The Coachella Valley Preserve also contains several palm oases that sit on top of San Andreas Fault lines. Underground water rises to the surface through these cracks. California Fan Palms (Washingtonia filifera) grow along the cracks where the water seeps up creating a desert oases.
Coachella Valley sits at the convergence of four vast ecological systems - the Colorado (or Sonoran) Desert, the Mojave Desert, and the coastal and peninsular mountain ranges.

This is the witness tree in Witness Tree Vineyard, which was used as a witness or bearing tree for the survey of the Claiborne O. Walker Donation Lane Claim #51. The survey was done on July 12th, 1854, and at that time this tree was 14" in diameter at the base. This is the first tree referenced on the attached page from the original survey notes. The tree is now about 4 ft. in diameter, though I did not measure it at the time of my visit.
