Bryophyllum delagoense (syn. B. tubiflorum, Kalanchoe delagoensis) and Bryophyllum × houghtonii

Mother-of-millions (Bryophyllum delagoense) is a category 3 restricted invasive plant under the Biosecurity Act 2014 because it spreads rampantly. It must not be given away, sold, or released into the environment. It has become a weed that infests grasslands, woodlands and open dunes, and is poisonous to stock.

Mother-of-millions has infested the Coochiemudlo Island Emerald Fringe particularly on the north-eastern, eastern, and south eastern shorelines of the island.

See the Queensland Government’s Mother-of-millions fact sheet (PDF).

Singapore daisy is a garden escapee and native of tropical America. It prefers moist areas on a range of soil types. If can be found in gardens, parks, bushland, disturbed areas, along roadsides, lawns and footpaths. It is becoming a problem by invading wetlands, irrigated areas and around drains. Found in South East Queensland and coastal areas of northern and Central Queensland.

Asparagus fern is a shrub originally introduced as a domestic ornamental plant, in a pot or as a ground cover. Now, in a wide range of coastal and sub-coastal habitats around Australia, it is an environmental weed. On Coochiemudlo Island it’s particularly invasive on the western side of the island where it has infested the Emerald Fringe.

Asparagus fern competes with native ground cover and under-storey plants by smothering other species and prevent their germination and establishment.

Asparagus fern is a native of eastern and southern Africa.

If you have asparagus fern in your garden, please dig it up, bag up the roots and rhizomes into a strong bag, and dispose of the bag at the tip — not into the green waste bins.

See Queensland Government fact sheet about Asparagus Fern.

Since it was introduced to Australia in the early 1900s, Ochna has been widely planted as a garden ornamental. Birds are attracted to the seeds that are then spread into bushland. On the island, Ochna has become invasive, particularly on the south-west of Coochiemudlo Island. It forms dense thickets that are hard to remove because of the very tough root system.

Larger plants may need to be grubbed out with mattock.

Other names for this weed are Mickey Mouse plant, Micky Mouse bush, bird's eye bush, carnival bush, small-leaved plane.

Ochna is native of southern Africa.

Herbicides are effective. See the Ochna fact sheet (PDF) for application rates.
