sage 'Blue Spire'


Salvia 'Blue Spire', also known as Perovskia, is a striking plant that boasts an attractive contrast of color and texture. Its appearance is characterized by a profusion of small, tubular deep blue or violet flowers that create a visually appealing effect. These blossoms are tightly packed into long, slender, and upright flower spikes, which bloom from midsummer to fall and are especially eye-catching when swaying gently in the breeze. The foliage of Perovskia is also noteworthy, presenting a delicate grayish-green color with a fine, lace-like texture. The leaves typically have a deeply incised shape, with a jagged or toothed edge, and they are often covered with fine hairs, giving them a soft, almost silvery look. The combination of these frosted leaves against the vibrant blue flowers is one of the plant's most distinctive features. Perovskia's overall form is that of a loosely branched shrub, with stems that tend to be square and sometimes show a hint of purple or white frosting. The plant's structure creates an airy and open appearance that can add depth and lightness to garden compositions. It is a hardy and resilient plant, often used in borders or as a focal point in garden designs due to its dynamic visual appeal and long blooming period.

  • water dropWater

    The Russian Sage should be watered deeply, allowing the soil to dry out between watering sessions to prevent root rot. During the growing season—spring and summer—watering typically involves 1 inch of water per week, depending on rainfall and soil conditions. In periods of drought or extreme heat, you may need to increase watering frequency. Reduce watering in the fall and even more so in the winter when the plant is dormant. An established Russian Sage may require watering only once every 2 to 3 weeks, depending on the climate and soil moisture. Always check the top 2 to 3 inches of soil for dryness before watering again.

  • sunLight

    Russian Sage thrives best in full sun, meaning it should receive at least 6 to 8 hours of direct sunlight each day. A spot that provides unobstructed sunlight, away from the shade of larger trees or buildings, will ensure the plant produces abundant flowers and maintains healthy growth. Russian Sage can tolerate some light shade, but flowering and foliage robustness may be compromised.

  • thermometerTemperature

    Russian Sage performs admirably in a range of temperatures but the ideal growing conditions are within the 60°F to 70°F range. It can tolerate maximum temperatures well above 80°F and can survive winter lows down to about -20°F. Plant hardiness zones for Russian Sage typically range from 5 through 9.

  • scissorsPruning

    Prune Russian Sage in the late winter or early spring before new growth starts. This helps maintain a tidy shape, encourages new growth, and can refresh an older plant that might have become woody. Pruning is also an opportunity to cut back any damaged or excessively long stems. Annual pruning of about one-third to one-half of the plant is recommended, as it responds well to being cut back and can become too large if left unpruned.

  • circleLife cycle

    Salvia 'Blue Spire', commonly known as Perennial Sage, begins its life cycle as a seed, which upon germination, develops into a small seedling with characteristic foliage. As it grows, the plant enters a vegetative stage, producing a rosette of leaves during the first season, followed by a more robust development of stems and foliage in subsequent years. In spring or early summer, Perennial Sage transitions to the reproductive stage, where it forms tall spikes of violet-blue flowers that attract bees, butterflies, and hummingbirds. After pollination, if seeds are produced, they will mature as the flowering spikes fade and dry out by late summer or early fall. Once the seeds are dispersed, the plant begins to prepare for dormancy, with foliage dying back in response to colder temperatures and shorter days. The plant overwinters as a crown with root system intact, ready to restart the cycle with new growth the following spring.

    • Propogation time

      Spring to early summer

    • Propogation: The ideal time to propagate Russian Sage, known botanically as Salvia 'Blue Spire', is during the spring or early summer when the plant is actively growing. The most popular method of propagation for this plant is by softwood cuttings. To do this, you select a healthy, non-flowering shoot and cut a 3 to 5 inch (approximately 7.5 to 12.5 cm) section just below a node. The lower leaves are then removed, and the cutting may be dipped in rooting hormone to increase the chances of successful rooting. The cutting should be placed in a well-draining soil mix and kept in a warm, humid environment with bright, indirect light. Roots typically develop within a few weeks, after which the new plant can be gradually acclimatized to typical growing conditions before being transplanted outdoors.
