BUSH INVADER
|
|
Tradescantia fluminensis |
| family: COMMELINACEAE |
| Description |
- A creeping, rapid-growing soft herbaceous plant from South America, favouring damp, shady nutrient-enriched areas.
- Stems are long, brittle, succulent and trailing, curving upwards at the tips; fine shallow roots grow at the leaf nodes.
- Leaves are shiny mid-green, eliptical with a point, smooth and slightly fleshy, sheathed where they join the stem. Can cause a severe contact allergy in dogs.
- Small white flowers with 3 triangular petals, spring to summer.
- A native plant look-alike, Scurvy Weed (Commelina cyanea), is distinguished by its blue flowers and fleshy roots.

| Dispersal |
Dumping of garden refuse; stem fragments root readily and can be washed down waterways or spread in mud from vehicles.
|
| Impact on Bushland |
Rapidly takes over the ground layer in gullies and temporary watercourses, forming a thick blanket of leaves that exclude light and warmth. Aggressively smothers low plants and seedlings, cools the soil, prevents native plant germination; highly invasive.
|
| Distribution |
Throughout the Blue Mountains.
|
| Alternative Planting |
Native Violet (Viola hederacea); Gotu Kola (Centella asiatica); Kidney Weed (Dichondra repens). Bugle Flower (Ajuga repens).
|
| Control |
Pull up, rake, or knife out; remove all stem pieces. Bag and send to tip. Follow the Principles of Bush Regeneragtion.
