Cissus rhombifolia 'Ellen Danica'

Oak Leaf Ivy / Ellen Danica Grape Ivy

Botanical Name: Cissus rhombifolia ‘Ellen Danica’
Family: Vitaceae
Origin: Central & South America (cultivar selection)
Plant Type: Evergreen climbing or trailing foliage plant

Overview

Cissus rhombifolia ‘Ellen Danica’, commonly known as Oak Leaf Ivy, is a highly adaptable foliage plant ideal for Adelaide’s shaded and protected garden spaces. Featuring finely divided, oak-like leaves with a soft, glossy texture, it offers a lush, cascading effect perfect for screens, pergolas, indoor–outdoor transitions, or shaded courtyards. In SA’s Mediterranean climate, it performs best in part shade with protection from harsh afternoon summer sun, thriving in moist, well-drained soils and producing long, trailing or climbing stems that create elegant vertical or hanging displays. While not fragrant, the foliage has a light, fresh green aroma when crushed and may develop bronze or reddish tints in cooler seasons. With minimal maintenance, it delivers year-round greenery and soft, tropical character.

Key Features

• Mature Size: 1.5–3 m long (climbing or trailing), width variable depending on support or pruning
• Growth Rate: 30–60 cm per year under good conditions
• Foliage: Finely cut, glossy mid-green leaves resembling miniature oak leaves; fresh new growth may appear bronze or reddish in cool weather
• Flowers: Insignificant small greenish flowers rarely produced in cultivation; grown purely for foliage
  
• Seasonal Interest: Evergreen year-round in Adelaide’s climate, with fresh new growth in spring and subtle cool-season foliage tints in winter
• Wildlife Value: Provides sheltering foliage for small insects and habitat for geckos or small garden fauna in protected outdoor settings
• Tolerance: Tolerates heat if provided shade; drought-tolerant once established but prefers regular moisture; wind-sensitive and best kept sheltered; not frost-hardy and may be damaged below 0 °C; unsuitable for full coastal exposure but performs well in protected coastal courtyards
• Planting Density: As a climber: plant 1–2 m apart along trellises or fences; As a groundcover or cascading plant: 1 per 0.5–1 m² or 1 per pot/hanging basket
• Pet Friendly: Generally regarded as non-toxic but ingestion may cause mild digestive upset; best to discourage chewing

Where It Works Best

• Sunlight: Part shade to bright filtered shade; morning sun acceptable; avoid strong afternoon sun in Adelaide’s climate
• Soil: Moist, humus-rich, free-draining loam; benefits from organic matter; avoid waterlogging
• Water Needs: Establishment: 2 deep soaks/week for 8–12 weeks; Established: Keep lightly to evenly moist; deep soak every 7–10 days in summer (more in heatwaves); minimal watering in winter
• Maintenance: Low-maintenance—trim to shape as needed; pinch growing tips to increase bushiness; provide support if training as a climber; mulch annually; fertilise lightly in spring with a balanced slow-release feed
• Lifespan: 10–20+ years in suitable sheltered outdoor or semi-indoor conditions
• Climate Zones: Best in temperate and Mediterranean SA locations—Adelaide plains (shaded sites), foothills, shaded city courtyards, and protected coastal gardens
• Soil pH: Neutral to slightly acidic preferred; tolerates mildly alkaline soils if drainage is good

Landscape & Design Ideas

• Soft, cascading foliage for pergolas, arbours or lattice screens
• Excellent in shaded courtyards, under verandahs, or in alfresco spaces where it adds a tropical feel
• A beautiful trailing plant for pots, hanging baskets, or large containers
• Ideal as a climbing green curtain along shaded walls or structural posts
• Pairs well with ferns, clivias, philodendrons, aspidistra and shade-loving natives for lush contrast
