Russian Sage (Perovskia): The Heat-Proof, Drought-Tolerant Perennial Star

When Southern summers scorch, Russian sage (Perovskia atriplicifolia) keeps blooming. Voted 1995 Perennial of the Year, this mint-family member (not a true sage, not from Russia) delivers lavender-blue flowers from summer to frost on aromatic, silvery foliage—asking only for sun, lean soil, and excellent drainage.

Quick Profile

• Zones: 5–9 (hardy to ~–40°F)
• Size: 3–5 ft tall and wide
• Foliage: Gray-green, fragrant
• Flowers: Purple-blue, tubular, in airy panicles
• Habit: Upright, slightly woody base

Culture: Treat It Like Lavender

• Sun: Full, all day
• Soil: Average to lean; no enrichment
• Drainage: Sharp—wet feet kill it
• Water: Very little once established; overwatering is the #1 killer
• Pruning: Light trim only; hard cuts cause dieback. Cut to 6″ in early spring.
• Mulch: Light layer at first frost

Considerations

• Bees love it. Site away from play areas if allergies are a concern.
• Messy bloom drop. Don't plant overhanging pools or patios.
• Flops if overfed/overwatered. Lean conditions keep it sturdy.
• Hummingbirds? Reports vary; bees are guaranteed.

Zero spraying, zero fertilizing, zero summer watering in Texas heat—that's as organic (and low-maintenance) as it gets. Check Dave's Garden Plant Files for photos and vendors.
