Tropical mid-sized tree, native to the southwestern US and northern
Mexico, members of the family Fabaceae. Parkinsonias have spiny
branches, leathery foliage and fragrant yellow blooms borne in drooping
racemes. They make a good hedge when sheared.

location in full sun The trees have a very fast growth rate
and reaches a height of 30 feet with a spread of 30 feet. Trees
may boom from the second year of growth. Some maintenance is
required (removing volunteer seedlings, cleanup of fallen seed
pods). Extremely drough tolerant, with a long tap root and
extensive root system, they are a good choice for low water areas.
Fragrant yellow blooms are followed by seed pods, 2 to 8 inches
long, rather like a bean pod, with clear separations between the
seeds. The pods are brown or tan in color.
Medicinally, Parkinsonia aculeata has been used to treat diabetes
and malaria. The seeds have been ground into flour. The
trees are excellent wildlife plantings as well.
Parkinsonia is best propagated by sowing seed. Seeds should be
sown in spring in pots or flats a soiless medium. Keep moist at
about 75F. Seedlings should be transplanted to larger containers
or into their permanent location when they are about 4inches in
height. Be careful not to break the taproot on the plant when
