A common landscape plant in desert regions of the American Southwest, this spiny tree is native to southwestern South America. Most plants sold under this name are unnamed and unarmed selections or hybrids. This semi-deciduous tree rapidly forms a dense spreading canopy of twisting branches. The bright green, fern-like leaves have numerous narrow leaflets. Plants may lose some or all of their leaves in winter, but soon refoliate. Fluffy catkin-like clusters of yellow flowers appear spring, followed by large, tan pods.
Though highly drought-tolerant, this sun-loving tree benefits from an occasional deep watering in spring and summer. Because of its aggressive root system and rapid growth, it is best suited to large properties and parks. (info source: Learn2Grow.com)

Abrade the seed coatings lightly with a file. Place the seeds in hot water and leave them to soak for at least eight hours to break them from dormancy.
Plant the seeds in a seed tray, using fresh seed starter potting mix. Cover the seeds with 10 mm (3/8") of potting mix. Place a humidity dome over the seed tray and place it in a warm location with indirect light.
Remove the dome once the seeds sprout and move the sprouts to a location with full light.
Transplant the sprouts once they reach 10 cm (4") into bigger pots.
Place the pots in a warm location, near a window where they will receive ample light. If ample light is not available, place a small grow light over mesquite trees.
