    About Brachychiton acerifolius

    Brachychiton acerifolius, the Illawarra Flame Tree, is a large Australian native with a straight trunk and a broad crown of glossy lobed leaves. In warmer summers it sheds much of that foliage and clothes the bare branches in scarlet bell flowers, which is the display the tree is known for.

    It grows best in full sun on deep, free draining soil and suits warm temperate and subtropical gardens through coastal New South Wales and Queensland. Young trees need protection from frost, although established specimens take light frosts in their stride. Growth is around 50 to 100 centimetres a year, and mature trees are notably drought hardy.

    The scale suits parks, rural properties, large gardens and civic landscapes, and it works as an avenue or street tree where the canopy has room. Allow 3 to 4 metres between trees for avenue work, more for a specimen. Buyers choose it for a summer flowering event that no other shade tree in the catalogue matches.

    Frequently Asked Questions

    About Illawarra Flame Tree

    What is the Illawarra Flame Tree?

    Brachychiton acerifolius is an Australian native tree from the rainforest margins of the east coast, in the family Malvaceae. It is grown for the mass of scarlet bell shaped flowers it carries in early summer, usually on bare or half bare branches. The leaves are glossy and deeply lobed, and older trees develop a thick, buttressed trunk.

    How big does Brachychiton acerifolius grow?

    In good ground it reaches 15 to 25 metres tall with a crown 8 to 12 metres across, so it is a tree for open space rather than a courtyard. Growth in cultivation is often slower and shorter than in habitat, but the mature footprint should still be planned for. Compact hybrids are available where the room is not there.

    Is it evergreen or deciduous?

    It is best described as semi deciduous. In most seasons it drops the majority of its leaves in late spring, flowers on the bare framework, then pushes new foliage straight afterwards. In warm frost free gardens the leaf drop can be partial and brief. In cooler districts the tree can stand bare for several weeks.

    When does it flower?

    Flowering runs from late spring into early summer, generally November through to January depending on the season and district. The display is triggered by warm dry conditions, so it is heavier in some years than others, and young trees often take several years before their first real flush. Flowers are followed by boat shaped seed pods.

    Is it frost tolerant?

    Only moderately. Established trees cope with light frosts, but young stock is easily damaged by hard or repeated frost and should be protected through its first few winters. It is a warm climate tree by origin, so cold inland sites with heavy frost are not its natural fit. Plant where cold air drains away rather than settling.

    Does it have invasive roots?

    The root system is not regarded as aggressive. Trees develop a thick tuberous taproot when young and a spreading anchoring system as they mature, and they are not known for lifting paving or entering drains. Even so, the trunk thickens considerably with age, so allow several metres of clearance from kerbs, footings and services.

    How do I care for an Illawarra Flame Tree?

    Water deeply through the first two summers to establish the root system, then it needs little supplementary water. Mulch out to the drip line and keep the mulch off the trunk. Prune only to remove damaged wood or to lift the canopy while the tree is young. A light application of a native fertiliser in spring is enough.

    Plant Your Brachychiton acerifolius (Illawarra Flame Tree) With:

    Enriched Planting Mix (AO Certified)

    Enriched Planting Mix is a certified organic blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent, bagged in 30L. It is built to be dug through existing garden soil at planting time rather than used on its own, and the gypsum is what sets it apart from a plain compost.

    Gypsum helps break up heavy clay so water and roots can move through it, while the compost and manure return organic matter and nutrient to tired ground. The coarse bark holds structure and keeps air around the root zone, and the wetting agent keeps moisture in the soil longer after rain or watering.

    Use it when planting trees, shrubs, roses, fruit trees and exotic garden plants, particularly into clay. Dig a hole twice the width of the pot and 7 centimetres deeper, then mix roughly one third planting mix through the excavated soil. Spread 7 centimetres of that improved soil in the base before setting the plant in.

    Frequently Asked Questions

    About Enriched Planting Mix

    What is Enriched Planting Mix made from?

    It is a blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent. Each part has a job. The compost and manure supply organic matter and nutrient, the gypsum works on clay structure, the bark keeps air around the roots and the wetting agent holds moisture in the soil.

    What plants is it suitable for?

    It suits exotic garden plants, including roses, ornamental and deciduous trees, fruit trees, shrubs and perennials, and it earns its keep most on heavy clay sites. It is a planting mix rather than a potting mix, so its job is improving soil at planting time. Phosphorus sensitive natives are the one clear exception.

    Is it safe for natives?

    No, not for the phosphorus sensitive ones. The composted animal manure in this blend lifts phosphorus well above what Proteaceae such as Banksia, Grevillea, Hakea and Protea will tolerate, and the result can be leaf burn, dieback and plant death. Use the Native Potting Mix for those species, or plant them into unimproved local soil.

    Is it certified organic?

    Yes. It is a certified organic product with no chemical additives, which is why the manure and compost in it are fully composted rather than raw. That makes it sound around fruit trees and vegetable beds, and it means you are adding genuine organic matter to your soil rather than a synthetic conditioner.

    How much do I need?

    Work on roughly one third planting mix to two thirds of the soil you dug out of the hole. For a shrub out of a 200 millimetre pot that is only a few litres. An advanced tree going into a large hole will take considerably more. Judge the quantity by the volume of the hole rather than the size of the plant.

    Can I use it in pots?

    It is not a potting mix and should not be used on its own in a container. The blend is designed to be diluted through garden soil, and used straight in a pot it holds too much water and settles badly. For containers, reach for a premium potting mix, or the native mix if you are potting natives.

    Does it need to be watered in?

    Yes. Water the plant well several hours before you plant it, then water thoroughly again once the hole is backfilled and the soil firmed down. That first deep watering settles the improved soil around the root ball and drives out air pockets. Keep the water up over the first few months while the roots establish.
