Gympie Stinging Tree
Dendrocnide moroides
Dendrocnide moroides, also known as Gympie gympie, is a tree in the nettle family Urticaceae. It is native to northeastern Australia and Indonesia. It's infamous for its extremely painful sting, caused by microscopic stinging hairs (trichomes) covering its leaves, stems, and fruits. The pain is described as intense, burning, and long-lasting, sometimes persisting for months or even years. The plant is a shrub or small tree, typically growing to a height of 1-3 meters. It has heart-shaped leaves with serrated edges and small, greenish-white flowers.

Australian Umbrella Tree
Heptapleurum actinophyllum
The Octopus Tree provides a contrasting texture and visual interest to the Gympie Gympie without direct competition for resources. Its size can also help provide a degree of protection from accidental contact with the Gympie Gympie's stinging hairs.
Macadamia Tree
Macadamia integrifolia
Macadamia trees, being larger and more robust, can easily outcompete Dendrocnide moroides for sunlight, water, and nutrients in the same area, hindering the Gympie Gympie's growth.
Steps:
- Take a stem cutting of about 10-15cm in length from new growth, ensuring the cutting includes at least 2-3 nodes.
- Remove the lower leaves from the cutting to prevent rotting.
- Dip the cut end of the stem in rooting hormone powder.
- Plant the cutting in a well-draining potting mix.
- Keep the soil consistently moist but not waterlogged. Place in a humid environment (e.g., covered propagation tray).
