Salvia nemorosa 'May Night'

Highly attractive to bees, butterflies, and hummingbirds.

Serves as an important nectar source during late spring and summer.

Deer and rabbit resistant — aromatic foliage deters browsing.

Adds strong ecological value to pollinator and wildlife-friendly gardens.

Spring: Rapid vegetative growth and early flower spikes form.

Summer: Peak flowering; continuous color from May through July.

Late summer to fall: Possible reblooming after pruning; gradual slowing of growth.

Winter: Dormant; dried stems can be left for winter interest and wildlife shelter before cutting back in spring.

Foundation or edging plant for sunny pathways

• Type: Deciduous, aromatic foliage with rough, slightly wrinkled texture.
  
• 
  Shape: Lance-shaped to ovate leaves with serrated margins.
  
• 
  Color: Deep green, forming dense basal rosettes.
  
• 
  When crushed, leaves release a distinctive, pleasant herbal scent that deters pests.
  

• Color: Deep violet-blue to purple flower spikes; richly saturated and long-lasting.
  
• 
  Bloom size: Dense spikes 10–12 inches tall, composed of many small tubular blossoms.
  
• 
  Bloom time: Late spring to midsummer, often reblooming in late summer after trimming.
  
• 
  Fragrance: Lightly aromatic, especially in warm weather.
  
• 
  Structure: Square stems typical of the mint family (Lamiaceae), giving an upright, architectural look.
  

Best planting time: Spring or early fall when temperatures are mild and soil is workable.

Site selection: Choose a sunny, open site with well-drained soil. Avoid heavy, waterlogged areas.

Hole preparation: Dig a hole twice as wide as the root ball and equal in depth to the container. Loosen compacted soil around the sides.

Soil improvement: Mix organic compost or aged manure into the backfill to enhance structure and drainage.

Planting depth: Set the crown level with the surrounding soil surface — planting too deep can cause crown rot.

Mulching: Apply a 2-inch layer of organic mulch (bark or shredded leaves) to retain moisture and suppress weeds, keeping it 1–2 inches away from the stems.

Spacing: Space plants 12–18 inches apart to allow good airflow and full mound development.

Initial watering: Water thoroughly after planting to settle the soil and eliminate air pockets.

• After first bloom: Cut spent flower spikes down to the basal foliage to encourage a second flush of blooms later in summer.
  
• 
  Seasonal maintenance: In late fall or early spring, cut plants back to about 2 inches above ground level to refresh growth.
  
• 
  Ongoing care: Remove faded flowers regularly to maintain appearance and extend flowering.
  
• 
  Periodic division every 3–4 years keeps clumps vigorous.
  

• Establishment phase: Keep soil evenly moist but not soggy until roots are established (usually 4–6 weeks).
  
• 
  Once established: Drought-tolerant; water only during prolonged dry periods.
  
• 
  Watering frequency: Deep, infrequent watering encourages deeper root growth.
  
• 
  Avoid overhead watering to reduce risk of fungal issues.
  

Prefers full sun — a minimum of 6 to 8 hours of direct sunlight daily.

Tolerates light shade, but too much shade reduces flower production and encourages leggy growth.

Plants grown in full sun have denser foliage, stronger stems, and more vibrant flower color.

Flower spikes can be cut for fresh bouquets or dried arrangements; harvest just as buds open for best color retention.

Can be propagated by division in spring or fall or by softwood cuttings in summer.

Low feeder — thrives without heavy fertilization.

In spring, apply a light dose of balanced, slow-release fertilizer (e.g., 10-10-10) or compost around the base.

Avoid high-nitrogen fertilizers; these produce excess foliage and fewer blooms.

A top dressing of compost each spring improves soil health and flowering vigor.

Performs best in well-drained, moderately fertile soil.

Adaptable to a wide range of soil types including loam, sandy, or slightly rocky soils.

pH preference: Neutral to slightly alkaline (6.5–7.8).

Avoid poorly drained or heavy clay soils — excessive moisture leads to crown rot or mildew.

• Pollinated by bees, butterflies, and hummingbirds, which are drawn to the nectar-rich tubular flowers.
  
• 
  Flowers are self-fertile but rely on insect activity for pollination.
  
• 
  Extended bloom period provides consistent nectar for pollinators throughout the summer.
  

• Complements a wide range of sun-loving perennials and ornamental grasses:
  
  
  Coreopsis verticillata ‘Moonbeam’ – soft yellow contrast with violet blooms.
  
  
  Echinacea purpurea (Coneflower) – similar cultural needs, attracts pollinators.
  
  
  Nepeta ‘Walker’s Low’ – extended bloom season with harmonious texture.
  
  
  Lavandula angustifolia – enhances fragrance and visual cohesion.
  
  
  Rudbeckia fulgida ‘Goldsturm’ – yellow contrast for late-summer color.
  
  
  Sedum ‘Autumn Joy’ or Perovskia atriplicifolia – great for drought-tolerant borders.
  
  
  
• 
  Excellent in mixed borders, rock gardens, and pollinator plantings.
