Parkinsonia - Jerusalem thorn or jelly bean tree
- 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.
