Russian Sage: The Late-Summer Blue Haze That Follows Lavender
Save
Russian sage is the straight species, the tall and airy original that newer compact selections are measured against. Wiry, whitish stems carry long sprays of tiny lavender-blue flowers over finely cut, silvery gray-green leaves, and at peak bloom the whole plant reads as a see-through haze of color.
Next to lavender it is almost a natural sequel. The two share the same hot, lean, sharp-draining ground, and Russian sage starts its show just as most lavender is winding down.

Why it belongs near lavender
English lavender peaks in early summer. Russian sage picks up the same silver-and-violet palette in late summer and holds it into fall, so a bed planted with both stays in color for months instead of weeks. Because it grows taller and looser than lavender, it works best behind it: lavender mounds in front, a soft blue cloud rising behind.
The leaves smell sharp and sage-like when brushed, so the pairing is fragrant too, just in two different keys. It was named Perennial Plant of the Year in 1995, and it has stayed popular for the simple reason that it is very hard to kill in a sunny, dry spot.

Planting and care
- Site: full sun in lean to average, well-drained soil. It is one of the best perennials for hot, exposed sites.
- Water: regularly through the first season, then rarely. Wet, heavy soil is the main risk, through root rot.
- Feeding: none. Rich, moist soil makes the stems lanky and inclined to lean, and the straight species leans more readily than compact selections.
- Spring: it leafs out late. Wait until new buds show, then cut the old stems back to roughly 6 to 12 inches, just above the lowest new growth.
- Fall: do not prune. The silvery stems look good standing in snow.
Most gardeners who lose Russian sage lose it in April, by deciding it is dead and digging it up. Give it until late spring before you worry.
Cutting and drying
The stems are good for fresh arrangements and dry well. Cut sprays when about half the flowers are open and hang them in a dry, shaded spot. A loose bundle of Russian sage and dried lavender keeps the blue-violet theme going indoors.
Bare root format
This listing is a bare root plant, a dormant root ready to go into the ground. Soak the roots briefly before planting, set the crown at soil level and water it in well. See the product page for current availability.
Frequently asked questions
Is Russian sage the same as kitchen sage?
No. It is grown as an ornamental and is not used for eating, even though the leaves have a sage-like scent.
Why is my Russian sage flopping?
Usually too much water, fertilizer or shade. Lean soil and full sun keep it more upright. If you want a shorter, stiffer plant, look at compact selections.
Will deer eat it?
Deer tend to leave it alone, which makes it a dependable partner for lavender in open gardens.
