Correa glabra

Common Names: 
Rock Correa
Distribution: 

Found on escarpments and rocky streambanks

Ecology: 

An important nectar-source for local honey-eaters in bushland areas. Valuable features are the very long flowering season and security of the nectar source (the tubular flower prevents nectar from being diluted or washed out by rain). The flowers are particularly attractive to the New Holland Honeyeater, Phylidonyris novaehollandiae and Eastern Spinebill. As with other heavy nectar producers in the Melbourne area these tend to be restricted to discrete environments (in this case, escarpments and streambanks). I have watched Eastern Spinebills 'patrolling' the Correa glabra bushes along a stretch of the Plenty River, securing for themselves the nectar from the bushes for themselves

Revegetation: 

Readily established in a range of environments, however, the association with rocky areas is a good clue about placement for appropriate places to re-establish this species

Gardening Hints: 

This bush makes an excellent garden subject, having many of the features of 'traditional' garden shrubs (dense green foliage, low wide habit which competes effectively with weeds). It is also very amenable to pruning and is extremely drought hardy once established. Moreover, it is capable of retaining these features in full sun, exposed windy conditions to light to moderate shade. These features more than make up for the comparative lack of excitement of the green flowers, which suffer in comparison to more colourful Correa species such as Correa reflexa, Correa pulchella and their numerous cultivars. Some red and green varieties of Correa glabra do exist but are localised.

As with other bird-pollinated species, garden plants are highly likely to cross-pollinate with plants in local bushland so care should be taken to avoid 'contaminating' the local populations with pollen from non-local forms. In the long term, the retention of distinctive natural variations will rely on gardeners being sensitive to this issue.

As with other prolific nectar bearing plants, they will inevitably become the focus for territorial honeyeaters which may make the garden uncomfortable for less aggressive insectivorous birds. Consider restricting them to a corner of the garden, (perhaps in a nectar 'patch' with Grevillea and Banksia species) in order to leave the rest of the garden accessible for Thornbills, Pardalotes, Wrens and so on.

Propagation: 

Within Melbourne few patches of Correa glabra set seed, therefore it is usually propagated by cuttings. Take cuttings when the tips are growing, which is usually late winter to the end of spring. Use a 3000ppm cutting gel or similar. Roots will appear in 3-5 weeks.

If the plants are dormant due to the extremes of winter or summer temperature, or droughted, they are much less likely to be successful, unless you have very good cutting facilities.
