About Salvia muelleri
Salvia muelleri, commonly known as 'Royal Purple' Autumn Sage, is a perennial shrub from the Lamiaceae family, prized for its vibrant spikes of deep purple flowers that bloom from late summer into autumn. Its aromatic foliage and compact habit make it ideal for garden borders, containers, or as a focal plant in low-maintenance gardens. It attracts pollinators and adds a splash of late-season color to the landscape.

Care tips
This sage thrives in full sun (at least 6 hours daily) and well-drained soil, preferably sandy or loamy, with a neutral to slightly alkaline pH. It is quite drought-tolerant once established but benefits from regular watering during dry spells, allowing the soil to dry out between waterings. A common mistake is overwatering, which can lead to root rot; ensure excellent drainage. Light pruning after flowering is recommended to maintain shape and encourage new growth.
