Plant Ideas for the Adelaide Hills

Written by Susan – Plant Lover, Adelaide

If you're lucky enough to call the Adelaide Hills home, you already know how unique the landscape is — rolling slopes, misty mornings, and cooler nights. But those same conditions can make gardening a little trickier than on the Plains or coast.

The good news? With the right plant choices, your Hills garden can be lush, colourful, and resilient all year round — from summer sunshine to chilly winter frosts.

Here are my favourite Hills-hardy plants from Adelaide Plant Co that thrive in the region's cooler, wetter climate and varied soils.

🌿 Top Plant Picks for the Adelaide Hills

🌸 Camellias (Sasanqua & Japonica)

A true Hills classic — glossy leaves and gorgeous blooms from autumn through spring.

• Thrive in part shade and rich soil

• Great for hedging, screening, or feature shrubs

• Frost-tolerant once established

🌳 Rhododendrons & Azaleas

Perfect for the cooler Hills air and sheltered spots. While we don't currently stock Rhododendrons, Hydrangeas are a beautiful companion plant that thrives in the same conditions.

• Stunning colour from late winter into spring

• Prefer dappled light and well-drained soil

• Combine beautifully with ferns or camellias

💚 Westringia fruticosa 'Grey Box'

Surprisingly versatile — works just as well in the Hills as on the coast.

• Hardy, compact, and beautifully silver-green

• Handles wind and light frost

• Great for neat hedges or native borders

🌺 Correa (Native Fuchsia)

An understated native that shines in the Hills climate.

• Tubular flowers attract birds through winter

• Tolerates frost and semi-shade

• Works well in naturalistic gardens

🍃 Rhaphiolepis indica 'Snow Maiden'

A resilient evergreen that still gives you flowers.

• Handles the Hills' mild frosts and varied soils

• Neat growth habit makes it ideal for structure

• Pink or white flowers in spring and autumn

🌾 Lomandra longifolia & Dianella Tasmanica 'Blaze'

Reliable, textural plants that hold their shape year-round.

• Drought and frost tolerant

• Great for borders, under trees, or driveways

• Add movement and contrast

🌼 Salvia Microphylla 'Hot Lips'

Sun-loving perennials that light up Hills gardens through summer.

• Frost-hardy once mature

• Great for bees, butterflies, and long flowering

• Perfect with grasses or in mixed borders

🌿 Pittosporum Tenuifolium 'Silver Sheen' & Escallonia 'Iveyi'

Frost-tolerant hedging shrubs that perform beautifully in the Hills' cooler climate.

• Both handle frost, wind, and variable Hills soils

• Pittosporum for year-round silver-green foliage

• Escallonia for dense evergreen coverage with white summer flowers

🍂 Betula Pendula 'Alba' (Silver Birch) & Acer 'Ruby Sunset'

Deciduous feature trees that truly come alive in the Hills' cool autumn air.

• Stunning autumn colour in cooler temperatures

• Perfect where autumn foliage is at its most spectacular

• Light winter structure once leaves drop

🌦️ Gardening Tips for the Adelaide Hills

• Soil prep is key: Add organic matter for drainage — Hills soils can be clay-heavy.

• Mulch generously: Protect roots from frost and retain moisture in summer.

• Choose the right position: Full sun for Salvias and Westringias; part shade for Camellias and Hydrangeas.

• Watch winter waterlogging: Raise beds or plant on slopes to avoid root rot.

• Windbreaks help: Use natives like Correa and Westringia to shield more delicate plants.

💚 Final Thoughts from Susan

"The Adelaide Hills are magic — misty mornings, crisp air, and gardens that burst into colour. The secret is picking hardy, climate-matched plants that love cool winters and warm summers. Once they're established, they'll reward you for years."
