Parkinsonia aculeata is a tree from the family Fabaceae; common names include Mexican Palo Verde, Parkinsonia, Jerusalem thorn, or Jellybean tree. It is native to the southwestern United States (western Texas, southern Arizona), Mexico, the Caribbean, South America south to northern Argentina, and the Galapagos Islands.
It grows from 2 to 8 meters high. The leaves and stems are hairless. The flattened leaf stalk is edged by two rows of 25-30 tiny oval leaflets; the leaflets are soon deciduous in dry weather, leaving the green leaf stalks and branches to photosynthesize. The branches grow sharp spines 7-12 mm long. The flowers are yellow and fragrant, 20 mm in diameter, growing from a long slender stalk in groups of eight to ten. The fruit is a pod, leathery in appearance, light brown when mature.
