Andean silver-leaf sage Salvia discolor
ABOUT
The plant known as Andean sage has striking visual characteristics that make it quite distinctive. The foliage of this plant presents an alluring contrast with its front side showing a green hue, while the underside is a rich purple or nearly black color. The leaves themselves are slightly wrinkled with a velvety texture, which only adds to the plant’s overall appeal. The stems are also similarly colored with the dark purple undertones, complementing the leaves and providing a cohesive look. Adding to its striking appearance, Andean sage produces flowers that are intensely colored; the blooms are a deep, inky purple to black hue and are nestled in showy green calyces. They grow in whorls, rising above the foliage and attracting attention with their unique color. This dark floral hue is quite rare and prized in plant collections for its dramatic contrast against the lighter colors typically found in gardens. The overall aesthetic of the Andean sage is one of moody hues and intriguing textures, creating a focal point wherever it is planted.

WaterThe Andean sage, also known as Salvia discolor, requires watering that ensures the soil is consistently moist but not waterlogged. During its growing season, typically, water the plant with approximately 16 to 24 onzes of water once a week, making sure that the topsoil feels dry to the touch before adding more water. In the winter months, reduce watering to every other week, ensuring that the soil does not completely dry out. Avoid overhead watering to prevent issues with mildew, instead aiming your water at the base of the plant to keep the leaves dry.
LightAndean sage thrives in full sun to partial shade conditions. The ideal spot for the plant is where it can receive a minimum of six hours of sunlight daily, which will encourage better blooming and healthy foliage. Avoid placing it in deep shade, as this will result in leggy growth and fewer flowers.
TemperatureThe Andean sage prefers temperate climates and is best suited to temperatures ranging from 50 to 80 degrees Fahrenheit. It can survive minimum temperatures down to about 40 degrees Fahrenheit and should be protected from frost. The ideal temperature conditions for maintaining a healthy Andean sage are between 60 and 70 degrees Fahrenheit.
PruningPruning the Andean sage is essential for maintaining its shape and promoting vigorous growth. Prune lightly in the spring and more aggressively after the main bloom period in late summer to encourage a second bloom. Remove any dead or diseased stems whenever noticed, and cut back the plant by one-third to half its size to keep it bushy.
CleaningAs needed
SoilAndean Sage prefers well-draining soil with added organic matter. A mix of equal parts loam, perlite, and compost is ideal. Maintain soil pH between 6.1 and 7.8 for optimal growth.
RepottingAndean Sage should be repotted every 1-2 years to replenish soil nutrients and prevent root bounding. Choose a pot slightly larger than the current one.
Humidity & MistingAndean Sage thrives in moderate to high humidity levels but is adaptable. Aim for about 40-50% humidity for best results.
Suitable locationsIndoor
Place Andean Sage in bright light and avoid overwatering.
Outdoor
Plant Andean Sage in sun to part shade and well-draining soil.

Life cycleThe life cycle of Salvia discolor, commonly known as Andean Sage, begins with seed germination, which requires well-drained soil and exposure to light; the seeds are sown on the surface, as they need light to germinate. Seedlings emerge and grow into juvenile plants, developing distinctive silvery-green foliage and a strong stem structure. As the plant matures, it enters the vegetative stage, where it grows its characteristic aromatic leaves and begins to form the infrastructure for its blooms. The reproductive stage follows, where purple-black flowers, rare among Salvias, emerge from bracts, usually in the summer or early autumn. These flowers attract pollinators, such as bees and hummingbirds, which facilitate cross-pollination. After pollination and flower wilting, the plant sets seed, completing its life cycle, and under suitable conditions, these seeds then disperse to give rise to new plants.
PropogationPropogation time
Spring-Early Summer
The Andean sage, also known as Salvia discolor, is most commonly propagated via stem cuttings. This method is effective because it allows for the creation of a new plant that is genetically identical to the parent plant. To propagate Andean sage, healthy, non-flowering stems should be selected during the active growth period, which is typically the spring or early summer. The cuttings, about 4 to 6 inches (10-15 cm) in length, should have their lower leaves removed and the cut end can be dipped in rooting hormone to encourage root development. The cutting can then be planted in a well-draining soil mix and kept moist but not waterlogged. Covering the cutting with a plastic bag can create a humid environment that is beneficial for root growth. It generally takes a few weeks for the cutting to root adequately before it can be transplanted to a permanent location.
