S. reginae is very popular as an ornamental plant. It is a common ornamental plant in Southern California, and has been chosen as the Official Flower of the City of Los Angeles.
It is propagated by division or from seeds, and is a low-maintenance plant that is easy to grow in the garden; it is fairly tolerant of soil conditions and needs little water once established. If cared for well, they will flower several times in a year. They will thrive in rich loamy soil, especially when they get plenty of water throughout the year. They do well in full sun to semi-shade and respond well to regular feeding with a controlled release fertiliser and compost. They are sensitive to cold and need to be sheltered from frost, as it can damage the flowers and leaves.
The flowers are, however, quite long-lasting once they appear. Peak flowering is in the winter and early spring. There is a yellow-flowered cultivar of this plant known as Mandela's Gold.
