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.
