Acacia greggii pdf

 

Catclaw Acacia (also called Devil's Claw Acacia) Acacia greggii, takes it name from the curved thorns that are found along the smaller branches. This semi-deciduous native of the American southwest and northern Mexico grows at a moderate rate to a height and width of 15 to 25'. It thrives in full sun and tolerates temperatures of 0° F. Catclaw can be found growing on canyon slopes, along arroyos and desert flats to elevations below 5000 feet. This specie has been present in the Sonoran Desert for over 12,000 years and individual specimens can live for 130 years. They are among the most drought tolerant trees in the Sonoran desert. Established trees can survive without supplemental irrigation but do best with monthly deep soaking during the hottest months (May through September). Two-inch long flowers spikes of mildly fragrant, cream to pale yellow flowers are produced from spring to fall.

 

Left unpruned, branches form a dense, thorny, spherical canopy that makes this an excellent security planting. Careful pruning reveals the graceful, twisted and gnarled trunks. Nursery grown specimens are trained into multiple trunked and single trunked tree forms. Gray-green leaves are made of finely divided leaflets that produce a dispersed canopy and filtered shade. Trees are fully deciduous in severe droughts. Its rustic trunks, natural form, summer flowers and hardiness make Catclaw Acacia an ideal accent or perimeter planting tree in high and low desert landscapes. These trees attract birds and other wildlife in landscapes that border native desert.
