About Your New Callistemon citrinus 'Endeavour'

Callistemon citrinus 'Endeavour' flowers close to year round, with the heaviest flushes of vivid crimson bottlebrush spikes through spring and summer. Very few screening shrubs deliver this much colour for this long, and the nectar keeps honeyeaters in the garden through most seasons.

'Endeavour' grows to 2 to 4 metres tall and 2 to 3 metres wide at 40 to 80 centimetres per year, filling in densely from ground level. The aromatic evergreen foliage releases a lemon scent when crushed, and the plant works as an informal screen, a mass planting, or a specimen in a large pot.

This Australian native is frost hardy, surviving heavy and frequent frost without damage, and tolerates poor soils, extended dry and periodic waterlogging once established. It grows in full sun and needs nothing beyond a light trim after each flowering flush.

Frequently Asked Questions

About Callistemon citrinus 'Endeavour'

How tall does Callistemon 'Endeavour' grow?

'Endeavour' grows to 2 to 4 metres tall and 2 to 3 metres wide with a dense habit. It is easily held lower with a trim after flowering.

When does 'Endeavour' flower?

It flowers close to year round, with the heaviest flushes through spring and summer. This extended flowering is its main advantage over single-season bottlebrushes.

Does 'Endeavour' attract birds?

Yes. The nectar-rich crimson flowers are worked heavily by honeyeaters, lorikeets and native bees, and the near year-round flowering keeps them coming back.

Why does the foliage smell of lemon?

Callistemon citrinus takes its name from the citrus scent released when the leaves are crushed. The aromatic oils also make the foliage unattractive to most browsing animals.

Is 'Endeavour' frost hardy?

Yes. It is frost hardy and survives heavy and frequent frost without damage, suiting it to inland tablelands as well as coastal gardens.

How far apart should I plant 'Endeavour' for a screen?

Plant 1 to 1.5 metres apart for a dense informal screen, or 2 to 3 metres apart where each plant should read as an individual shrub.

Does 'Endeavour' tolerate wet ground?

Yes. Like most bottlebrushes it handles periodic waterlogging better than most screening shrubs, which makes it useful along drainage lines and in low-lying corners.

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.
