Winter in Perth may bring cooler temperatures and shorter days, but that doesn’t mean your garden has to look bare and lifeless. In fact, Western Australia’s Mediterranean climate allows for a surprisingly vibrant winter garden — if you choose the right flowers.
With thoughtful planning and plant selection, it’s entirely possible to enjoy a colourful, fragrant, and flourishing outdoor space through the colder months. Whether you’re a seasoned gardener or just beginning to explore the joys of winter gardening, this guide will help you select the best flowers for a Perth winter garden, along with planting tips and care advice to keep your patch thriving until spring.
🌿 Why Winter Gardening Works in Perth
Perth’s winters are relatively mild compared to the eastern states, with daytime temperatures averaging between 16°C and 19°C, and only occasional overnight frosts. The cooler weather and winter rains provide an excellent opportunity for planting a wide range of annuals, perennials, and bulbs that don’t fare well in the scorching heat of summer.
The key benefits of winter gardening in Perth include:
- Consistent rainfall to support new plantings
- Fewer pests such as aphids and whiteflies
- Cooler temperatures that reduce water stress
- Lower evaporation rates for more efficient watering
So, what should you plant to make the most of your winter garden in Perth?
🌸 1. Pansies and Violas – Colourful and Cold-Tolerant
No winter garden in Perth is complete without pansies and violas. These cheerful blooms come in a kaleidoscope of colours and thrive in cool temperatures.
Why they’re ideal:
- Tolerate cold nights and light frost
- Bloom continuously through winter
- Great for garden beds, pots, and hanging baskets
Care tips:
Plant in well-drained soil and deadhead regularly to encourage more blooms. Fertilise monthly with a liquid feed to maintain vigour.
🌼 2. Calendulas – Golden Winter Warmth
Also known as pot marigolds, calendulas are bright, sun-loving flowers that bloom brilliantly through the cooler months.
Why they’re ideal:
- Easy to grow from seed
- Edible petals add colour to salads
- Attract beneficial insects like bees and hoverflies
Care tips:
Calendulas prefer full sun and regular watering. Pick spent blooms to prolong flowering and prevent self-seeding if desired.
🌷 3. Sweet Peas – Fragrant and Climbing
If you’re looking for fragrance in your winter garden, sweet peas are a must. These climbing annuals add vertical interest and fill the air with their classic, sweet perfume.
Why they’re ideal:
- Thrive in cool weather
- Available in a variety of colours and forms
- Can be trained up trellises, fences, or arches
Care tips:
Sow seeds directly in autumn or early winter in a sunny spot. Provide support early and water regularly. Picking flowers encourages more blooms.
🌺 4. Primulas and Polyanthus – Winter Border Favourites
Perfect for mass plantings, borders, and pots, primulas and polyanthus produce clusters of bright blooms in rich hues of red, pink, purple, and yellow.
Why they’re ideal:
- Excellent winter bedding plants
- Compact growth and long flowering season
- Tolerate light shade and partial sun
Care tips:
Keep soil moist but not soggy. Feed with a balanced fertiliser every few weeks. Snip off faded flowers to promote fresh blooms.
🌼 5. Snapdragons – Tall, Textured, and Tough
Snapdragons (Antirrhinum) bring a vertical element to winter gardens, with their tall spikes of velvety, dragon-shaped flowers.
Why they’re ideal:
- Come in dwarf, medium, and tall varieties
- Bloom best in cool weather
- Attract bees and add structure to garden beds
Care tips:
Plant in full sun with good drainage. Water at the base to avoid fungal issues. Tall varieties may need staking in exposed areas.
🌸 6. Cyclamen – Perfect for Shaded Spots
Cyclamen are a winter staple in Perth, especially for adding colour to shady corners of the garden or patio.
Why they’re ideal:
- Thrive in cool, sheltered areas
- Ideal for pots, under trees, or as indoor plants
- Heart-shaped leaves and elegant blooms
Care tips:
Avoid overhead watering — water from below to prevent rot. Protect from strong rain and excessive moisture.
🌿 7. Native Winter Bloomers – A True Aussie Touch
Some of WA’s native plants also flower in the winter months, adding natural character and supporting local pollinators.
Top picks include:
- Grevillea ‘Winter Delight’ – Compact with red and cream flowers
- Hakea laurina (Pincushion Hakea) – Unique, showy blooms
- Banksia varieties – Especially B. menziesii and B. prionotes
Care tips:
Native plants prefer free-draining soil and minimal fertiliser. Choose a sunny position and water only during prolonged dry spells.
🌷 Bonus: Winter Bulbs to Plant Now
Late autumn to early winter is the perfect time to plant spring-flowering bulbs, which will start to shoot during the winter months.
Top choices include:
- Daffodils – Classic yellow trumpets that thrive in Perth’s climate
- Hyacinths – Intensely fragrant and colourful
- Freesias – Easy to grow and sweetly scented
Plant bulbs in well-drained soil or pots and keep moist but not waterlogged.
