About Your New Osmanthus x burkwoodii

Osmanthus x burkwoodii, or Burkwood osmanthus, is a compact evergreen shrub with an upright bushy habit, a garden hybrid between Osmanthus delavayi and Osmanthus decorus. The small dark green leaves are leathery and glossy, and in spring the whole plant carries clusters of little white flowers with a heavy sweet scent.

It grows 2 to 3 metres tall and 1.5 to 2 metres wide at about 15 to 30 centimetres a year. Full sun to part shade suits it, in any well-drained soil. Cool temperate through to warm temperate gardens all work, frost is handled easily, and water matters mainly in the first summers.

Plant it 80 centimetres apart for a clipped formal hedge, 1 to 1.5 metres apart for a soft screen, or 3 metres apart down an avenue. Single plants hold their own near a seat or path where the spring fragrance is noticed. This is a hedge that asks for one trim a year.

Frequently Asked Questions

About Burkwood Osmanthus

What is Osmanthus x burkwoodii?

Burkwood osmanthus is a compact evergreen shrub, a garden hybrid between Osmanthus delavayi and Osmanthus decorus. It forms an upright bushy plant of small, leathery, dark green leaves, and in spring it carries dense clusters of little white tubular flowers with a strong sweet fragrance that carries across a courtyard.

How big does Burkwood Osmanthus grow?

It reaches 2 to 3 metres tall and 1.5 to 2 metres wide at maturity, growing about 15 to 30 centimetres a year. Clipped as a hedge it is easily held at 1.5 metres or lower. The habit is naturally neat, so it fills out from the base without the bare legs many shrubs develop.

How far apart should I plant it for a hedge?

For a tight formal hedge plant 80 centimetres apart. For a fuller informal screen allow 1 to 1.5 metres between plants and let them knit together over two to three seasons. If you are running it as an avenue of clipped shapes, 3 metres apart gives each plant room to develop evenly.

When does it flower?

Spring, roughly September to November, with the heaviest display in the middle of that window. The flowers are small and white in tight clusters along the stems, and the fragrance is strong enough to fill an enclosed garden. Prune after flowering rather than before if you want the full display each year.

Does it need sun or shade?

Full sun to part shade both work. Full sun gives the densest growth and the heaviest flowering, while part shade suits it in hot inland gardens where afternoon protection helps. It will grow in more shade than that, but the plant opens up and flowers less. Avoid deep shade under dense evergreens.

Is it frost hardy?

Yes. It handles frost comfortably once established and is a dependable choice for cool temperate districts, including the tablelands and Victorian and Tasmanian gardens. It also grows well in milder coastal and warm temperate areas. Young plants benefit from steady water through their first two summers, which matters more than winter protection.

How do I prune and care for it?

Trim once a year straight after flowering, taking the new growth back to shape. A second light tidy in late summer keeps a formal hedge crisp. Water regularly for the first two summers, then only through long dry spells. Mulch the root zone and feed with a general fertiliser in early spring.

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: Tip prune in late winter and again in summer to build dense growth. For a formal hedge, light shaping two to three times a year keeps lines crisp.

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 inspection for psyllids or scale in warm humid conditions is all that's needed.
