Arizona's landscape allows for plant
species that run the gamut from true desert species
in the south, to high altitude fir and pine trees in the
north.  There are mountains, deserts, canyons,
valleys, plateaus, prairies and rivers, each with their
own collection of tree species.  Arizona is home to 6
national forests such as the Apache-Sitgreaves
National Forests, an oasis in the arid southeast and
home to more lakes and rivers than in any other
Southwestern National Forest.  Another national
forest, Tonto National Forest, is the fifth largest

State Tree: Blue Palo Verde
forest in the United States and contains 21 threatened or endangered wildlife species.
     Arizona is also home to such wonders as the Sky Islands, where the end of the ice age left pockets of plants behind.  Ponderosa pine, quaking aspen, fir, and spruce trees are the hallmark trees of the high elevation forests.  Pinyon and Juniper are common species as well, adding year round greenery and the bonus of harvesting pine nuts and juniper berries.  There are flowering trees such as palo verdes and desert willows, and thorny trees like honeylocust and mesquite, dotting the landscapes and adding splashes of spring color and caution for the curious.  Arizona has a diverse natural beauty and a dazzling array of flora and fauna surely to enchant anyone from the casual hiker to the eco-tourist.  You can marvel at the towering petrified forest, go skiing the next day and round the weekend out by fishing for trout on one of the many beautiful lakes.  In Arizona, it is easy to find a place to get away from it all and settle into relaxation and discovery.
Blue Palo Verde, Parkinsonia florida, was named the state tree in 1954.  Palo verde means green stem or bark, which is a tell tale feature of this species.  It is a fast growing tree, is leafless most the year, and is aided in photosynthesis by the green bark. Blue Palo Verde also has smooth green branches.
     In the spring, Blue Palo Verde erupts with small bright yellow flowers that seem to cover the entire crown.  Like all members of the pea family, Blue Palo Verde trees have long, somewhat flat, yellowish brown seed pods which fall when ripe.  They are then eaten by wildlife and dispersed.  The leaves are bi-pinnately compound with 2 to 3 pairs of .5 inch long leaflets on each pinnae and have a delicate feathery appearance similar to acacia or mesquite trees.
     Blue Palo Verde is one of the few tree species found in the Sonoran Desert amidst the Giant Saguaro cactus forest.  It is capable of enduring temperatures over 100
°F for long periods and minimal precipitation.  It makes an excellent xeric landscape species.
     The fruits of this native species are edible.  Native Americans, specifically the Pima and Papago peoples, cooked young fruits and seeds and made porridge from ground seeds.
