Senna artemisioides ssp. x sturtii

This beautiful shrub, now known as Senna, was previously included in the genus Cassia.

Taxonomists have made changes to the names of many species of this genus, to reflect their relationship better.

Hybridisation occurs readily amongst plant varieties, sub-species and species of the genus. This often results in ‘hybrid swarms’ with a range of intermediate characteristics, making it impossible to distinguish between the species.

A very decorative garden shrub, it can be used as an informal hedge and can be easily grown beneath mature eucalypts. Best suited to inland areas, but also adaptable to coastal regions. This plant can be grown in free draining soils that are either acidic or alkaline. It does best in a sunny position and will tolerate light frosts. Drought tolerant, it responds well to hard pruning in spring.
