Care of the plant Senna spectabilis or Whitebark senna

The genus Senna, family Fabaceae, comprises 250 species of shrubs and trees native to temperate regions of all continents (especially South America and Australia). Many species of the genus Cassia are included in this genus. Some species are: Senna spectabilis, Senna didymobotrya, Senna corymbosa, Senna artemisioides, Senna multiglandulosa, Senna sturtii, Senna candolleana.

Common names: Whitebark senna, Spectacular cassia. This species is native to South and Central America.

They are deciduous trees with a rounded crown that reach 12 meters in height. The leaves are paripinnate, bright green in color and are made up of more or less elliptical leaflets. The showy yellow flowers appear in large axillary clusters and are scented. They bloom from late summer until late fall. The fruits are black pods up to 30 cm long.

They are used as an isolated specimen in the garden but are also very suitable for alignments in parks, avenues or squares.

Senna spectabilis grows in full sun or light shade exposure and in hot climates. They do not resist frost; the winter safety temperature is 5 ºC.

They do not resist calcareous soils; use a light garden soil that contains organic matter.

Water frequently, without flooding, so that the soil is always damp and does not dry out completely.

Fertilize in early spring with compost or manure.

They do not need pruning.

They are quite resistant plants to pests and diseases; they can be attacked by aphids if they suffer from drought.

They are propagated by woody cuttings or from seeds sown in spring.
