About Your New Albizia 'Persian Silk Tree'

Albizia julibrissin, the Persian Silk Tree, is a deciduous tree with a broad flat topped crown and doubly divided leaves that fold up at night. Through the warm months it carries powder puff flowers in clear pink, each one a tuft of fine silky stamens, held right across the top of the canopy.

Growth is fast, 60 centimetres to 1 metre a year, reaching 6 to 12 metres high and 6 to 8 metres across. It wants full sun and free-draining soil, copes with poor ground and reflected heat, and once dormant it is properly frost hardy. A late frost can burn new spring growth without lasting harm.

The flat canopy throws light dappled shade, which makes it useful over a terrace, a courtyard or a carpark bed where a dense canopy would feel too heavy. Bare winter branches let sun back through to the house. Seed pods hang on after leaf fall and any seedlings pull out easily.

Frequently Asked Questions

About Persian Silk Tree

What is the Persian Silk Tree?

Albizia julibrissin is a deciduous tree with a broad flat topped crown and finely divided fern-like leaves that fold up at night and in rain. Through the warm months it carries pink powder puff flowers made of fine silky stamens, held across the top of the canopy. It belongs to the pea family.

How big does the Persian Silk Tree grow?

It reaches 6 to 12 metres high and 6 to 8 metres wide, with the canopy usually broader in proportion than the height suggests. The spread is the figure to plan around when choosing a position. In smaller gardens it can be held toward the lower end of that range with formative pruning.

How fast does it grow?

Fast, 60 centimetres to 1 metre a year while young, slowing as it approaches full height. Trees planted at a larger container size usually flower within two or three seasons. That speed is useful where shade is needed quickly, though the timber is not especially strong, so shelter it from severe wind.

When does the Persian Silk Tree flower?

From late spring into summer, mostly December through February, with the heaviest display in midsummer. The flowers are lightly fragrant and last several weeks, and bees and honeyeaters work them constantly. Flat brown seed pods follow in autumn and hang on the bare branches through winter.

Is it evergreen or deciduous?

Deciduous. It drops its leaves through the colder months and leafs out again in mid to late spring, noticeably later than most deciduous trees. That habit is useful on a north facing terrace, where the canopy shades in summer and the bare branches let winter sun through to the house.

Is it frost tolerant?

Yes, and more so than is often assumed. Once dormant it handles hard frost, which is why it performs in Canberra, Orange and inland Victoria as well as in warm coastal gardens. The risk is a late frost catching new spring growth, which burns the tips but does not harm an established tree.

How do I care for the Persian Silk Tree?

Water through the first two summers, after which it copes with dry spells on its own. Prune in late winter while dormant to lift the canopy and remove crossing branches, which helps the flat crown develop evenly. Rake up seed pods if you would rather not have seedlings; they pull out easily when small.

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.

Watering: Water deeply twice weekly through the first 12 months. Once established, reduce to once weekly in dry periods. Mulch helps maintain consistent moisture.

Mulching: Apply a 5 to 7 centimetre layer of organic mulch over the root zone, keeping it 5 centimetres clear of the trunk.

Pruning: Minimal pruning required. Light tip prune in late winter to maintain shape, and remove lower branches as the tree grows to develop a clean feature trunk.

Fertilising: Apply a slow-release general-purpose fertiliser in early spring and again in autumn for steady growth and consistent foliage colour.

Pest and disease: Hardy against most pests and diseases. Occasional scale or caterpillar inspection in warm humid conditions is all that's needed.

Albizia 'Persian Silk Tree' performs best in well-drained loam or sandy loam with a slightly acidic to neutral pH. Adaptable to a wide range of soils when drainage is improved with organic matter.

Sandy soil: Free-draining and ideal. Mulch well to maintain consistent moisture.

Clay soil: Improve drainage with gypsum and organic compost before planting.

Loam: The preferred soil for steady root development and consistent growth.

pH: Slightly acidic to neutral preferred. Mulch with composted leaf litter to maintain levels naturally.
