Although some of these plants are rather difficult or even impossible to grow in cultivation, especially those from specialised environments, many are still worth a try.
For example, the Red Flowering Gum Corymbia ficifolia, like many plants, was once considered by most experts as unsuitable for gardens for a range of reasons.
However, a few visionaries persevered with breeding and grafting and in recent years have successfully created Corymbia cultivars that would be worthwhile in a garden of any size.
The Kangaroo Paw, Anigozanthos, was once also regarded as unsuitable for the average garden after many years of failure until recent hybrids like the ‘Bush Gems’® range was developed.
Despite many other examples of early failures, some experts have succeeded and still continue to develop other cultivars of Australian plants that will soon include succulent plants.
Gardeners can play a role here as many succulent plants are easy to raise from seed. (Also see artilce on Calandrinias for other successful examples).
