Use in horticulture

The tiny leaves, shiny red new growth and feathery flowers of this verticordia have been described as "attractive" features and the plant has been cultivated since 1991. Propagation has usually been from cuttings and the plants have established in sand with gravel in full sun. They are relatively drought and frost hardy as well as resistant to the fungal disease that affect some other eremophilas.
