Salvia nemorosa ‘Blue By You’ (Sage)

Salvia nemorosa ‘Blue By You’: Endless Sapphire Spires for Pollinators and Effortless Color

Imagine stepping into your garden on a cool spring morning—waves of deep blue spires rise above lush, green foliage, alive with bees, butterflies, and even the occasional hummingbird. Your border hums with life, and the rich color continues all summer, never missing a beat. That’s the magic of Salvia nemorosa ‘Blue By You’—a modern meadow sage bred for reliability, repeat blooming, and pollinator power.

History & Breeding

‘Blue By You’ emerges from the world-renowned breeding at Darwin Perennials, blending genetics from Salvia nemorosa and Salvia pratensis. This vigorous hybrid was selected for outstanding season-long bloom, impressive branching, and rugged garden adaptability. It’s a 2023 All-America Selections winner and a highlight at university trial gardens for durable performance from early spring well into autumn. Created for today’s gardeners, it’s a breakthrough in heat, frost, and cold tolerance—no more fret about summer browning or harsh winters!

Description

This improved meadow sage forms low, mounded clumps of aromatic, wrinkled green leaves, sending up stiff, square stems dotted with tightly-packed, electric-blue, tubular flowers. ‘Blue By You’ stands out for its size—reaching up to almost 2 feet—and blooming repeatedly with lower maintenance than older salvias. The color and sheer flower power set it apart, shining from early spring to the first frost (especially when spent blooms are snipped away).

Native Habitat

While bred for gardens, ‘Blue By You’ draws on traits of native and naturalized sages of Europe and western Asia, thriving in sunny, dry, open meadows and grassy steppe regions. Its wild ancestry makes it tough, adaptable, and essential for pollinator gardens everywhere.

Plant Type and Habit

It’s a classic clump-forming perennial, with neat basal rosettes and strong, upright stems. The local density, branching, and clear vertical lines bring structure to any mixed bed, from wildflower meadows to patio containers.

Plant Size

‘Blue By You’ matures at 20–22 inches tall (with flowers), spreading 18–22 inches wide—a perfect front or mid-border plant, or royal accent for massed sweeps.

Flowers

Long-lasting, repeat-flowering blue spikes, each bloom a nectar beacon to pollinators. The two-lipped flowers form in whorls along the upright stems, and individual spikes can persist for weeks. Blooms begin early (up to two weeks before other varieties) and keep coming: up to five full cycles if regularly deadheaded.

Foliage

Aromatic, lance-shaped leaves with a wrinkled, fuzzy surface, arranged in lush ground-hugging mounds—even the foliage deters browsing animals and fills the garden with herbal freshness.

Hardiness

• USDA Zones: 4b–9a, tolerating cold to -30°F (-30°C)
• Weather Tolerance: Heat, frost, humidity, and drought

Award

• 2023 AAS Perennial Winner

Uses

• Star in cottage gardens, wildflower meadows, and vibrant pollinator plantings
• Excels in modern, low-maintenance borders and xeriscapes
• Adds vertical impact, color contrast, and pleasing aroma to patios and walkways
• Helps stabilize soil and thrive in pollinator strips and urban gardens

Wildlife

Nectar-rich flowers are irresistible to bees, butterflies, and hummingbirds. ‘Blue By You’ actively supports a healthy pollinator ecosystem from early spring into fall.

Deer and Rabbit Resistance

The aromatic, slightly hairy foliage is distasteful to deer and rabbits, keeping your planting pristine even where browsing is heavy.

Drought and Heat Tolerance

After establishment, ‘Blue By You’ shrugs off summer dry spells and heat—ideal for modern drought-wise landscapes.

Toxicity

Like most ornamental salvias, ‘Blue By You’ is considered non-toxic to people and pets.

Invasiveness

Clump-forming and virtually non–self-seeding (sterile hybrid). Stays where planted and is easy to thin if needed.

How to Grow and Care for ‘Blue By You’ Sage

Light

Needs full sun for best bloom (6–8 hours daily); partial shade tolerated but may reduce flowering.

Soil

Performs best in moderately rich, well-draining soils—tolerates loam, sand, and gravel. Avoid heavy clay or standing water.

Watering

Water deeply to establish; reduce thereafter. Once established, water only when the soil is dry several inches down.

Fertilization

Fertilizer is rarely needed—too much makes plants floppy. Use light compost or a balanced organic mix in early spring if desired.

Pruning

Deadhead spikes after first bloom to trigger rebloom. In late fall or very early spring, shear to a tidy mound for lush new growth.

Potting and Repotting

Grows beautifully in sunny containers with well-drained mix. Repot in spring if needed for continued vigor.

Overwintering

In colder zones, no special care is needed; mulch lightly to protect roots if winter extremes threaten.

Propagation & Plant Protection

‘Blue By You’ (USPP31,033) is a protected, largely sterile hybrid.

Common Problems with ‘Blue By You’

Pests

• Aphids: Sap-sucking insects—treat by spraying with water or insecticidal soap.
• Spider mites: Dry, hot weather encourages outbreaks—hose leaves or use horticultural oil.

Diseases

• Powdery mildew: Rare, appears in prolonged humidity—improve spacing and air circulation.
• Root rot: Soggy soil or poor drainage—ensure well-drained beds.
• Leaf spot: Prune out affected leaves, avoid overhead watering.
• Rust: Remove infected stems promptly.

Legginess

• Too little sunlight results in floppy, stretching growth—ensure full sun for best posture.

Self-Seeding

• Not a rampant spreader, but can sow modestly—deadhead if unwanted seedlings appear.
