Tulbaghia simmleri

Pink Society Garlic

Botanical Name: Tulbaghia simmleri
Family: Amaryllidaceae
Origin: Southern Africa
Plant Type: Clumping evergreen perennial (strappy)

Overview

A taller, showier cousin of society garlic, Tulbaghia simmleri brings bold pink blooms and broad, blue-green foliage to Adelaide gardens. Flowering prolifically from spring to autumn, it offers excellent drought tolerance, a neat clumping habit, and a mild garlic scent—ideal for water-wise borders, cottage gardens, and large containers.

Key Features

• Mature Size: 40–60 cm H × 40–60 cm W; 60–80 cm H in flower
• Growth Rate: 25–45 cm per year under good conditions
• Foliage: Broad, strappy blue-green leaves; forms dense, arching clumps
• Flowers: Showy pink to mauve-pink tubular blooms in dense umbels on tall, sturdy stems—spring through autumn (peak late spring/summer)
• Seasonal Interest: Evergreen year-round with extended warm-season flowering; foliage persists through Adelaide winters
• Wildlife Value: Excellent for pollinators—attracts bees, butterflies, and native insects
• Tolerance: Drought, heat, wind & light coastal exposure once established; light frost may brown tips (recovers quickly); adapts to a range of soils including Adelaide's limestone-influenced loams; avoid prolonged waterlogging
• Planting Density: Border/edging: 3–4 plants per linear metre; Mass planting: 5–7 plants/m² for full coverage
• Pet Friendly: Generally non-toxic; mild stomach upset possible if eaten—discourage pets from chewing

Where It Works Best

• Sunlight: Full sun to part shade (full sun yields more flowers and tighter growth)
• Soil: Well-drained loam, sandy loam, or clay loam; tolerates Adelaide's alkaline soils; excellent in raised beds and pots
• Water Needs:
  • Establishment: Deep soak twice weekly for 8–12 weeks
  • Established: Deep soak every 10–14 days in summer (increase during heatwaves or for containers); minimal to no watering in winter unless prolonged dry spells
• Maintenance: Deadhead spent blooms to prolong flowering; trim back tatty foliage in late winter; divide clumps every 3–5 years to maintain vigour; light feed (slow-release or compost) in early spring—avoid excessive nitrogen to prevent soft, leafy growth at the expense of flowers
• Lifespan: 10–20+ years (long-lived with periodic division)
• Climate Zones: Thrives in Adelaide's Mediterranean climate; suited to temperate and warm temperate SA regions including coastal and inland areas
• Soil pH: Slightly acidic to mildly alkaline (pH 6.0–7.5); performs well on Adelaide's calcareous soils

Landscape & Design Ideas

• Feature plant in cottage or Mediterranean-style borders with lavender, salvia, and ornamental grasses
• Mass planting in water-wise garden beds or nature strips
• Bold structural accent in large containers for patios, courtyards, or pool surrounds
• Mixed perennial beds alongside agapanthus, dianella, and native grasses
• Cut flowers for fresh arrangements—long-lasting stems with a gentle fragrance
