You can use bottlebrush as a feature tree to attract birds and bees; in a regularly spaced row to screen neighbourly views; as a groundcover over an embankment; or as a low hedge at hip-height.
Encourage an autumn flush of bottlebrush (Callistemon sp.) with a little native plant food. Trim the finished flowers 5cm behind the brushes to keep them compact and long-living.
Graham’s favourite is ‘Harkness’ which is also known as ‘Gawler hybrid’ (5m). He says it has ‘the best and longest red brushes, is a great street tree and because it’s a hybrid has no ugly seed capsules’.
The best deep-pink varieties are ‘All Aglow’ (2.5m) and ‘Hot Pink’ (2m).
A recent purple-flowering release, ‘Purple Splendour’ (2m) is on trial in Linda’s coastal garden.
