Plants in Australia: 8 Beautiful, Pet-Safe Picks for Cool-Climate Gardens

If you live in a cool, temperate part of southern Australia and share your home with a curious dog or cat, you don’t have to limit your garden to native flora to get year-round color and visual interest. Many non-native ornamental plants in Australia thrive in regions like Victoria, Tasmania, and the NSW tablelands, with no risk to curious pets that may nibble on foliage. This guide covers 8 low-fuss, pet-safe picks perfect for cool-climate gardens, from striking small trees to shade-loving flowering perennials.

What to Consider When Choosing Plants in Australia for Cool-Climate Gardens

Before you pick new additions for your garden, there are a few key factors to keep in mind to ensure your new plants thrive long-term. First, assess your light conditions: some varieties need full, direct sun for 6+ hours a day, while others prefer dappled partial shade, especially during the hottest afternoon hours.

Next, consider humidity and rainfall. Cool temperate regions often get consistent, moderate to high rainfall, which many ornamental non-native plants prefer over the arid or tropical conditions found in other parts of the country. If you have long dry spells in summer, you will only need to water regularly to keep soil moisture consistent.

Most importantly, confirm any new additions are pet-safe if you have dogs or cats. All the picks on this list are classified as non-toxic to pets, so you won’t have to worry if your pet takes a curious bite of leaves or flowers.

Stunning Japanese Maple Trees for Australia Gardens

Japanese maples are some of the most popular ornamental trees for cool-climate Australia plants collections, and for good reason. They come in a huge range of sizes, foliage colors, and growth habits, so you can find an option that works for tiny patios, large garden beds, or container growing. They are naturally adapted to cool, humid conditions, so they thrive in southern Australia’s temperate zones without the need for specialized care.

Many varieties offer year-round interest, from fresh spring foliage and delicate spring flowers to bold fall color and textured bark that stands out in winter. All varieties listed below are pet-safe, making them a worry-free pick for family gardens.

Full-Sun Japanese Maple Varieties for Bright Outdoor Spaces

If you have a sunny garden bed or patio that gets 6+ hours of direct sun a day, these four full-sun tolerant Japanese maple varieties will thrive:

• Arakawa Cork Bark Japanese Maple: This standout tree is known for its distinctive rough, cork-like bark that adds visual interest even in winter when leaves drop. It produces small, delicate spring flowers, and its green foliage shifts to warm gold and orange tones in fall. It grows to a medium size, making it a great focal point for medium to large gardens.
• Autumn Fire Japanese Maple: As the name suggests, this variety is famous for its vibrant, fiery red fall foliage that stands out in any garden. Its leaves emerge soft green in spring, deepen to rich green in summer, and burst into bright red as temperatures drop in autumn. It adapts well to most well-draining soil types.
• Brandt’s Dwarf Japanese Maple: Perfect for small spaces or container growing, this compact variety only reaches a maximum height of 2 feet at maturity. It has dense, finely cut green foliage that shifts to bright orange and red in fall, and it fits easily on even the smallest apartment patio.
• Glowing Embers Japanese Maple: This bold variety has deep purple foliage from spring through summer, which shifts to brilliant crimson in fall. It grows to a small to medium size, making it a great statement tree for smaller gardens or as a contrasting planting next to green-leafed varieties.

All four of these varieties are humidity-loving, so they are well-suited to high-rainfall cool regions with minimal extra care required.

Partial-Shade Japanese Maple Picks for Dappled Light Spots

If your garden has dappled light, such as under taller established trees, or an east-facing patio that gets gentle morning sun and afternoon shade, these two partial-shade friendly Japanese maples are ideal:

• Aka Shigitatsu Sawa Japanese Maple: This eye-catching variety has variegated green and white foliage with delicate pink edges on new spring growth. The variegation stays consistent through summer, and the leaves shift to soft gold and orange in fall. It does not tolerate harsh, direct afternoon sun, which can scorch its delicate leaves.
• Golden Fullmoon Maple: This variety has rounded, bright yellow-gold leaves that seem to glow in soft, indirect light. Its foliage holds its golden color through summer, then shifts to warm orange and red in fall. It grows to a small to medium size, and it pairs beautifully with darker-leafed plants in shaded garden beds.

Both of these varieties will stay healthier and retain their foliage color better when protected from harsh midday and afternoon sun.

Flowering Plants in Australia for Added Garden Color

Pair your Japanese maples with these two low-growing, pet-safe flowering perennials to add layered color and texture to your garden beds:

• Chinese astilbe 'Vision in Red': This shade-loving perennial produces tall, fluffy deep red plume flowers in mid-summer, which rise above its lush, fern-like green foliage. It thrives in damp, shaded spots, making it the perfect planting under the dappled light of a Japanese maple canopy. It is low-maintenance, and it will come back year after year with minimal care.
• Jack-in-the-pulpit: This unique perennial has striking hooded green and purple flowers in spring, followed by bright red berries in late summer (note: while the foliage and flowers are pet-safe, the berries may cause mild stomach upset if ingested in large quantities, so you may want to remove them if you have a very curious pet). It prefers damp, shaded soil, so it works well in the lowest, wettest parts of shaded garden beds.

Both of these flowering plants are adapted to cool temperate climates, so they will thrive alongside your Japanese maples with no extra specialized care.

Quick Care Tips for Ornamental Australia Plants

All the picks on this list are low-maintenance, but these simple tips will help them stay healthy and vibrant for years:

• Mulch around the base of Japanese maple roots with a thick layer of organic mulch, such as bark chips or leaf mold, to retain soil moisture and regulate root temperature. Keep mulch a few inches away from the trunk to prevent rot.
• Water deeply during extended dry summer spells, especially for potted varieties, which dry out faster than plants in garden beds. Aim to keep soil consistently moist but not waterlogged.
• Prune only dead or damaged branches in late winter, when the tree is dormant. Japanese maples do not need heavy pruning to maintain their shape, and over-pruning can damage the tree.
• Fertilize lightly in early spring with a slow-release, balanced fertilizer to support new spring growth. Avoid over-fertilizing, which can lead to excessive, weak growth that is prone to damage.
