The flowers are usually white, emerging from coloured bracts. It is not frost hardy, but is often grown in warmer latitudes for its prominent arching velvety blue or purple inflorescences.
It grows up to 1.3 m (4.3 ft) high and 2 m (6.6 ft) wide, with numerous erect stems, often arching at their tips, and with long inflorescences. The linear-lanceolate leaves are a soft mid-green, with whitish, hairy undersides.

This plant has ornamental value in the garden, and has gained the Royal Horticultural Society's Award of Garden Merit. It is a low-maintenance plant that grows best in full sun and moist but well-drained soils. Flowers attract butterflies, bees and hummingbirds.
Uses
A recent analysis of the essential oil of S. leucantha found it to be rich in the sesquiterpene hydrocarbons; β-caryophyllene, α-guaiene, cis-muurola-3,5-diene, germacrene D, and bicyclogermacrene. Bornyl acetate constituted 23.9% of the oil.
