Cercidium floridum

Fabaceae

  • Blue palo verde is a moderate sized tree reaching up to 25 feet in height. It is common in washes in the lower desert areas of California where it often occurs with desert ironwood. Blue palo verde species of the Coachella Valley and Salton Sea basin, it is also widespread cross the broader Sonoran Desert outside of Califoria. The bark of the blue palo verde is a distinctive blue-green, it has spines at each node and leaves with clear petioles.

  • The blue paloverde is distinguished from foothills paloverde by larger, fewer leaflets, and by all-yellow flower petals with small red spots. This tree has a bluer cast that its foothills counterpart and is more restricted to plains and margins of dry washes. Both native paloverdes are now classified by some botanists as Parkinsonia species, because of hybridization with the introduced Mexican paloverde (P. aculeata). The blue paloverde has a very brief April-May bloom period most years, but aberrant individuals may make a few floral buds as early as February or as late as October. Most trees bloom synchronously over a 10-day or three-week period, peaking the last week of April. "Arizona Highways Presents Desert Wildflowers, 1988".

It is easily recognized when fruits are present because of the shape of the pods with a tightly coiled pattern of growth. Screwbean mesquite is generally restricted in California to areas with permanent or semi-permanent groundwater, but generally is not able to root to depths more than about 10-15 feet.
