Cassia fistula L.
Cassia fistula, commonly known as Indian laburnum, purging cassia, is a tree.
Cassia fistula was described by Carl Linnaeus in 1753. The name is considered as validly published. The common name is 'Golden Shower'.
The trees have a rounded to broadly spreading canopy and reach heights of 8 to 12 metres.
Wood and Bark
The trunk of the tree is thick and brown. It requires constant pruning, if grown as a garden tree.
Cassia fistula is evergreen. The dark-green, paripinnate leaves are alternate. The leaflets are ovate and have entire margins.
Flowers and Fruits
Cassia fistula produces racemes of pendant, yellow cup-shaped flowers from April to July. The fruits are elongated purple-brown pods with poisonous seeds.
Cassia fistula is native to India.
The trees prefer a sunny situation on moist soil. The substrate should be gritty loam. They tolerate temperatures only above at least 1Â°C (USDA zone 10).
Tolerance of special soil conditions
- none: drought
- high: city climate
The ornamental value of Cassia fistula lies especially in its fragrance.
Maintenance and Propagation
The plants usually require only a moderate amount of maintenance.
