What is a Russian Sage?
Russian Sage (Perovskia atriplicifolia) is a stunning perennial plant known for its graceful appearance, aromatic foliage, and abundant lavender-blue flowers. Despite its name, Russian Sage is not a true sage (Salvia spp.) but belongs to the mint family (Lamiaceae). This resilient plant is native to Central Asia, particularly regions in Russia and Afghanistan.
What does Russian Sage look like?
Russian Sage has several distinctive features that make it a popular choice for gardens:
- Foliage: The plant’s foliage consists of finely textured, silvery-gray leaves that have a soft, fuzzy texture. The aromatic foliage emits a pleasant, sage-like scent when brushed or crushed, enhancing its appeal.
- Growth Habit: Russian Sage has an upright and bushy growth habit, reaching a height of 2 to 4 feet (60 to 120 centimeters) and spreading to about 3 to 4 feet (90 to 120 centimeters) in width. Its stems are woody at the base and covered in grayish-brown bark.
- Flowers: Russian Sage produces striking lavender-blue or violet-blue flowers that appear on tall, slender spikes. These flowers are composed of small tubular blooms, which create a feathery and airy appearance. The blooms are highly attractive to bees, butterflies, and other pollinators, making Russian Sage a valuable plant for supporting beneficial insects.
- Blooming Season: Russian Sage typically blooms from mid-summer through early fall, providing an extended period of floral display. The flowers create a beautiful contrast against the silvery-gray foliage, adding a burst of color to the garden when many other plants may be winding down.

- Low Maintenance: Russian Sage is relatively low-maintenance, requiring minimal care once established. It is resistant to most pests and diseases and is also deer-resistant, making it a suitable choice for gardens in areas with browsing wildlife. Regular pruning in early spring, cutting the plant back to a few inches above the ground, helps maintain its shape and encourages robust growth.
- Landscape Uses: Russian Sage adds beauty and interest to garden landscapes. It works well as a border plant, in perennial beds, or as a focal point in a xeriscape or cottage-style garden. Its airy growth habit also creates a lovely contrast when planted alongside other shrubs or perennials.
Russian Sage’s combination of silvery foliage, aromatic scent, and abundant lavender-blue flowers make it a captivating addition to any garden. Its ability to withstand hot and dry conditions while attracting pollinators adds to its appeal as a low-maintenance and visually stunning perennial plant.
Where is Russian Sage native?
Russian Sage (Perovskia atriplicifolia) is native to several regions in Central Asia. It is primarily found in countries such as Russia, Afghanistan, Pakistan, and Iran. In Russia, it is native to the steppes and hillsides of the southwestern regions, including the provinces of Samara, Saratov, and Volgograd. Russian Sage has naturalized in various parts of the world, including North America and Europe, where it is widely cultivated for its ornamental value.
Russian Sage is not considered invasive in most regions. While it is a vigorous grower, it generally does not spread aggressively or outcompete native plant species. Russian Sage is well-behaved in garden settings and is not known to exhibit invasive tendencies.
However, it is essential to note that invasive potential can vary depending on the specific region and ecological conditions. In some areas with favorable climates and disturbed habitats, Russian Sage may self-seed and establish itself more readily. It is always advisable to check with local invasive species lists or consult with regional gardening experts to determine if Russian Sage is invasive in your specific location.
When planting, it is recommended to monitor seedlings and remove any unwanted plants to prevent self-seeding and potential spread into natural areas. Regular pruning and deadheading can also help control seed production and limit potential spread.
Growing Guide
Growing Russian Sage (Perovskia atriplicifolia) is relatively easy, and it can add a touch of elegance to your garden. Here are some key steps to successfully grow Russian Sage:
- Sun and Soil Requirements: Russian Sage thrives in full sun, so choose a location in your garden that receives at least 6 to 8 hours of direct sunlight per day. The soil should be well-drained, as this plant is sensitive to waterlogged conditions. If your soil is heavy or clay-like, amend it with organic matter like compost to improve drainage.
- Planting Time: It’s best to plant Russian Sage in spring or early fall when the temperatures are milder. This gives the plant time to establish its roots before facing extreme weather conditions.
- Planting Process: a. Dig a hole that is wider and deeper than the root ball of the plant. b. Gently loosen the roots of the Russian Sage plant. c. Place the plant in the hole, ensuring that the top of the root ball is level with or slightly above the soil surface. d. Backfill the hole with soil, gently firming it around the plant. Avoid compacting the soil too tightly to allow for proper root growth.
- Watering: While Russian Sage is drought-tolerant once established, it’s crucial to provide sufficient water during the initial planting phase. Water deeply after planting to settle the soil around the roots. Afterward, water the plant thoroughly only during dry spells or extended periods of drought. Avoid overwatering, as this can lead to root rot.
- Mulching: Apply a layer of organic mulch around the base of the plant, leaving some space around the stems to prevent excessive moisture buildup. Mulching helps conserve moisture, suppress weeds, and regulate soil temperature.
- Pruning: Pruning Russian Sage is optional but can help maintain its shape and promote better flowering. The best time to prune is in early spring before new growth emerges. Cut back the previous year’s growth to about 6 to 12 inches above the ground. This encourages new growth and a compact form. You can also deadhead spent flowers throughout the blooming season to promote prolonged flowering.
- Maintenance: Russian Sage is generally low-maintenance, but regular care will ensure optimal growth: a. Fertilizer: Russian Sage doesn’t require heavy fertilization. If needed, you can apply a balanced, slow-release fertilizer in spring. Follow the package instructions for the appropriate amount. b. Dividing: Every few years, if the plant becomes crowded or loses vigor, you can divide Russian Sage in early spring. Dig up the clump, carefully separate it into smaller sections, and replant them in suitable locations. c. Pests and Diseases: Russian Sage is relatively resistant to pests and diseases. However, keep an eye out for common issues like powdery mildew or aphids. Treat any infestations with appropriate organic control methods.
By following these guidelines, you can enjoy the beauty and resilience of Russian Sage in your garden. Its silvery foliage, aromatic scent, and abundant blooms will create a striking presence and attract beneficial pollinators.
When to harvest
Harvesting Russian Sage (Perovskia atriplicifolia) is a simple process that can be done to collect stems with flowers for decorative arrangements or to dry the foliage for various crafts. Here is a straightforward guide on when and how to harvest Russian Sage:
Timing:
- Harvest stems with flowers when the plant is in full bloom, typically in late summer or early fall.
- Harvest foliage throughout the growing season, preferably before the plant starts to decline in late summer or early fall.
Harvesting Method:
- Stems with flowers: Use clean and sharp pruning shears or scissors to cut the stems just above a leaf node or junction. This stimulates branching and encourages the plant to produce more blooms. Choose a day when the weather is dry and the flowers are fully open and vibrant.
- Foliage: Trim individual leaves or small leaf clusters from the plant using clean scissors or pruning shears. Select healthy and mature leaves for harvesting.
Post-Harvest Care:
- Remove any damaged or wilted flowers or foliage before using or drying.
- For immediate decorative use, place the freshly harvested stems with flowers in a vase or container filled with water. Replace the water regularly to maintain their freshness. You can also place the harvested foliage in water to enhance arrangements if desired.
- For drying purposes, bundle the stems or foliage together using string or a rubber band. Hang the bundles upside down in a cool, dark, and well-ventilated area. Ensure they are not crowded to allow for proper air circulation. The drying process may take a few weeks. Once fully dried, you can use the flowers or foliage for crafts, wreaths, or dried flower arrangements.
Remember to follow local regulations and guidelines when harvesting plants from public or protected areas. Always leave enough foliage on the plant to ensure its continued growth and health.
While Russian Sage is not typically harvested for culinary use, it’s important to note that the plant is not considered edible and should not be consumed.

How to propagate Russian Sage
Russian Sage (Perovskia atriplicifolia) can be propagated through several methods, including seed sowing, division, and softwood cuttings. Here’s a guide on how to propagate Russian Sage:
- Seed Propagation:
- Collect mature seeds from the dried flower heads of Russian Sage.
- Start the seeds indoors in late winter or early spring. Fill seed trays or pots with a well-draining seed-starting mix.
- Sow the seeds on the surface of the soil and lightly press them into the soil, but avoid covering them completely as they require light to germinate.
- Mist the soil to moisten it and cover the trays or pots with plastic wrap or a clear lid to create a greenhouse-like environment.
- Place the trays or pots in a warm location with indirect sunlight.
- Keep the soil consistently moist but not waterlogged.
- Seeds should germinate within 2-4 weeks. Once the seedlings have developed a few sets of true leaves, they can be transplanted into larger pots or into the garden after the last frost date.
- Division:
- Divide mature Russian Sage plants in early spring or early fall when the plant is dormant or just starting to grow.
- Dig up the plant carefully, ensuring you preserve as much of the root system as possible.
- Gently separate the clump into smaller sections, making sure each division has a healthy portion of roots and shoots.
- Replant the divisions in well-draining soil in a suitable location, spacing them apart according to their mature size.
- Water the divisions well after planting and continue to keep the soil moist until they become established.
- Softwood Cuttings:
- Take softwood cuttings in late spring or early summer when the new growth is still flexible and not woody.
- Select healthy, non-flowering shoots and cut 4-6 inches (10-15 centimeters) in length.
- Remove the lower leaves from the cuttings, leaving only a few at the top.
- Dip the cut end in rooting hormone to encourage root development (optional).
- Insert the cuttings into a well-draining potting mix or a mixture of perlite and vermiculite.
- Place the cuttings in a warm and bright location with indirect sunlight.
- Mist the cuttings regularly to keep the humidity high and the soil slightly moist.
- Rooting should occur within 4-6 weeks. Once the cuttings have rooted and developed a healthy root system, they can be potted up individually or transplanted into the garden.
Remember to provide adequate care and attention to newly propagated Russian Sage plants, including regular watering and protection from extreme weather conditions, until they become established.
Propagation allows you to expand your Russian Sage collection or share these lovely plants with other garden enthusiasts. Enjoy the process and the satisfaction of growing new plants!
