Hardenbergia violacea 'Meema'

Meema Hardenbergia / Purple Coral Pea

Botanical Name: Hardenbergia violacea 'Meema'
Family: Fabaceae
Origin: Cultivar (species native to eastern and southern Australia)
Plant Type: Evergreen climbing vine / groundcover

Overview

A spectacular Australian native climber perfectly suited to Adelaide's Mediterranean climate, Hardenbergia violacea 'Meema' is prized for its profuse display of cascading purple-violet pea flowers that smother the plant from late winter through spring. This vigorous cultivar forms dense coverage of glossy dark green foliage on twining stems that climb fences, walls and arbors or cascade elegantly as groundcover. The masses of vibrant purple flower sprays appear when gardens need colour most, creating stunning vertical displays or carpet-like coverage. Fast-growing, drought-tolerant once established, and exceptionally versatile, it thrives in Adelaide's conditions while providing year-round evergreen screening and spectacular seasonal flowering. Ideal for covering fences, screening structures, erosion control on slopes, or spilling over retaining walls, 'Meema' brings reliable winter-spring colour and low-maintenance elegance to South Australian landscapes.

Key Features

• Growth Rate: 60–100 cm per year under good conditions (fast-growing and vigorous)
• Foliage: Narrow, lance-shaped glossy dark green leaves (5–10 cm long); evergreen—provides year-round coverage and screening
• Flowers: Masses of deep purple-violet pea-shaped flowers (1–1.5 cm) in cascading sprays (5–10 cm long); prolific display late winter–spring (Jul–Oct in SA); highly ornamental
• Fragrance: Lightly fragrant (subtle sweet scent; not overpowering)
• Seasonal Interest: Late winter–spring spectacular purple flower cascade; year-round dense evergreen foliage; attractive seed pods follow flowering
• Wildlife Value: Attracts Nectar-feeding Birds (honeyeaters, wattlebirds); Good for Pollinators (native bees); provides dense habitat and nesting sites
• Tolerance: Excellent drought tolerance once established; good heat tolerance; frost-hardy to -7°C; good wind tolerance once established; coastal-tolerant; low phosphorus requirement (native); adapts to wide range of conditions
• Planting Density: Fence/wall coverage: 1 plant per 2–3 m; Groundcover: 1–2 plants per m²; Excellent in large containers with trellis support
• Pet Friendly: Generally safe (not known to be toxic; foliage generally not palatable to pets)

Where It Works Best

• Sunlight: Full sun to part shade (best flowering in full sun or morning sun; tolerates dappled shade; performs well on east and north-facing aspects in Adelaide)
• Soil: Well-drained loam, sandy loam or clay loam; tolerates Adelaide's alkaline soils; adapts to a wide range of soil types including poor soils
• Water Needs:
  Establishment: Deep soak 2 times weekly for 8–12 weeks
  Established: Deep soak every 2–3 weeks in summer; fortnightly once well-established; minimal watering in winter; highly drought-tolerant once established
• Maintenance: Low to moderate maintenance; prune after flowering to control size and maintain shape; can be pruned hard if overgrown; tip-prune young plants to encourage bushiness; mulch annually; use low-phosphorus native fertiliser sparingly if needed; virtually pest and disease-free
• Lifespan: 15–25+ years
• Climate Zones: Ideal for Mediterranean and temperate South Australia—Adelaide plains, foothills, Fleurieu Peninsula, Adelaide Hills; performs exceptionally well in Adelaide's conditions
• Soil pH: Slightly acidic to alkaline (pH 6.0–8.0); adapts well to Adelaide's calcareous soils

Landscape & Design Ideas

• Covering fences, walls and trellises for rapid evergreen screening with spectacular late winter–spring purple flower display
• Cascading over retaining walls, embankments and slopes for erosion control with ornamental appeal
• Groundcover for large areas, under trees or on difficult slopes where low-maintenance native coverage needed
• Pergola and arbor coverage creating seasonal purple canopy; softens hard structures with flowing evergreen growth
• Large containers with trellis or obelisk support for patios and courtyards; can be trained as standard or allowed to cascade over pot edges
