About Your New Brachychiton populneus x acerifolius 'Bella Donna'

Brachychiton populneus x acerifolius 'Bella Donna' crosses the Kurrajong with the Illawarra Flame Tree, producing a slender upright tree carrying dense lobed foliage. Through late spring and summer it hangs clusters of pink bell shaped flowers along the branches. Unlike its flame tree parent it holds its leaves through the flowering period in most gardens.

Full sun brings the best flowering, and the tree accepts clay, loam or sandy ground provided water moves through it. Once settled in it takes light to moderate frost and long dry spells, inheriting the toughness of the Kurrajong side of the cross. Growth runs about 50 to 80 centimetres a year with very little intervention.

The narrow habit suits nature strips, driveways, courtyards and townhouse gardens where a full sized flame tree would crowd the space. Councils plant it for streets and avenues at roughly 3 metres apart, or 3 to 4 metres for individual specimens. It gives flowering colour without the canopy width of either parent.

Frequently Asked Questions

About Bella Donna Brachychiton

What is Brachychiton 'Bella Donna'?

It is a named hybrid between Brachychiton populneus, the Kurrajong, and Brachychiton acerifolius, the Illawarra Flame Tree. The cross keeps the drought hardiness and neat upright form of the Kurrajong while adding the pink to red bell flowers of the flame tree. It is an Australian native selection grown for street and feature planting.

How big does Bella Donna grow?

Expect 6 to 8 metres in height with a canopy 3 to 4 metres across in most Australian gardens, which is roughly a third of the size of a mature Illawarra Flame Tree. The habit stays upright and fairly narrow, so it fits verges and side boundaries where a broad crowned tree would not.

How fast does it grow?

Height gain is around 50 to 80 centimetres a year once the tree is away, which is steady rather than rapid. Growth is quickest in the first few years on a well prepared site with regular water, then slows as the canopy fills out. Advanced stock shortens the wait to a useful size considerably.

When does it flower?

Flowering runs through spring and summer, with the heaviest flush from late spring onwards, roughly November into January. The bell shaped blooms are pink through to soft red and are carried in clusters along the branches. Warm dry spring weather produces a stronger display, and trees usually flower from a young age.

Is it drought tolerant?

Yes. The Kurrajong parentage gives it a deep root system and a genuine tolerance of dry conditions once established, which is why it is used widely in inland and western districts. It still needs regular water through the first two summers. After that, occasional deep soakings in a long dry summer are all it asks for.

How far apart should I plant it for an avenue?

For a uniform avenue or street row, plant at 3 metres apart so the canopies meet and read as a continuous line. Where each tree should stand as a separate specimen, allow 3 to 4 metres so the full form can develop. Keep trees a few metres clear of kerbs, footings and underground services.

How do I care for Bella Donna?

Water deeply once or twice a week through the first two summers, then taper off. Mulch the root zone but keep mulch away from the trunk collar. Prune only for shape or to remove crossing branches, ideally in late winter before the new season starts. A slow release native fertiliser in early spring supports flowering.

Enriched Planting Mix (AO Certified)

$21.95

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.
