Several variants of this species are known but presumably the single-corolla, white-flowered plant is the wild form. In Australia, only the multiple-corolla, purple-flowered form with usually deeply purple-tinged branches and leaves, described above is known to occur outside cultivation.
In the past, the name D. metel was widely misapplied, in Australia and elsewhere, to D. inoxia and D. wrightii.
