Parkinsonia - Jerusalem thorn or jelly bean tree

Weed Habitat 

  • Parkinsonia is thought to be native to tropical America but has spread throughout the world as an ornamental and shade tree.
  • As Parkinsonia is adapted to an extremely wide range of soil types, there is little doubt that it will continue to spread through watercourses and adjoining areas throughout the sub-humid and semi-arid environments of Queensland.


  • A hairless shrub or small tree, rarely to 10m high.
  • Slender green photosynthetic zig-zag branches armed with sharp spines.
  • Leaves with a short, spine-tipped stalk, leaf branches 20-40 cm long, flattened with small, oblong leaflets along each edge.
  • Flowers yellow, fragrant, five petalled, each on a long, slender drooping stalk.
  • Seeds oval, hard, about 15 mm long, borne in pencil-like pods 5-10 cm long, constricted between the seeds.
