Plant Perovskia atriplicifolia 'Sage Advice' in a sunny spot when you want tall, airy blue-purple flower spikes and silvery foliage that stays attractive through the growing season. This Russian sage selection forms a sturdy, upright clump and blooms for weeks in summer into fall, adding movement and soft color without feeling heavy.
Give it full sun and well-drained soil. It handles lean, dry sites well once established, so it is a strong choice for xeric and low-water beds, hot exposures, and tough corners where many perennials struggle. Water regularly the first season to help roots settle in; after that, water only during extended dry spells.
At maturity it typically reaches 32-36 inches tall and spreads about 28-32 inches wide, so space plants to allow airflow and keep the clump full from base to tip. In late winter or early spring, cut stems back to encourage fresh new growth and a tidy habit. Avoid heavy, wet soils in winter and do not over-fertilize; both can reduce performance.
Hardy in USDA Zones 5-9, it is useful in borders, along sunny paths, and mixed with ornamental grasses and other sun-loving perennials. The aromatic foliage and long bloom period make it a dependable summer performer and a great backdrop for pollinator-friendly plantings.
