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.
