Russian Sage grows as a perennial, woody herb, also known as Perovskia "Blue Spire" and by its scientific name, Perovskia atriplicifolia. Its tall, thin stems of grey-green develop spires of profuse, tiny, lavender-blue flowers. The plant may reach 4 feet tall and spread in a mass 3 feet wide. Russian Sage serves as an ornamental plant, as opposed to the like-named sage used for cooking. Plant Russian Sage in the spring.
Purchase a Russian sage plant from a nursery catalog or local nursery or garden center. Purchasing an established plant cuts down on the time spent waiting for Russian Sage to become more of a visual asset to your garden design.
Select an adequate growing location. Russian Sage prefers well-drained, moderately fertile soil and full sun. Use Russian Sage in a dedicated garden, a plot by itself or in raised beds. Amend the soil to attain the right balance of nutrients. Local county extension offices will test a soil sample for you and suggest any needed additions to your garden soil.
Read the label that comes with your plant. This will alert you to any special planting recommendations. Plant in the spring, according to USDA Plant Hardiness Zone for your area.
Dig a hole in your prepared location as deep and as wide as the sage's current container. Sprinkle a time-release fertilizer into the hole, and remove the plant from its container. Place it in the hole, keeping plant's existing soil level even with surrounding ground level. Back fill the planting hole and tamp down to secure.
Water the new plant right after planting to it settle in to its new environment and prevent the plant from going into shock from the transplant. Apply a water-soluble commercial brand or organic solution fertilizer approximately every six weeks to establish the plant in its new location and renew depleted nutrients throughout the growing season.
