Plectranthus ciliatus
Plectranthus is a perennial weed commonly found in shaded areas, like bush and tree lined creek banks. It grows into a dense mat, which smothers large areas and outcompetes native plants. It's native to South Africa and was originally introduced as an attractive ornamental plant in the 1970s. Unfortunately, it escaped through garden waste dumping and invaded local ecosystems.
Plectranthus can be mostly found growing in shady areas with moist, well-drained soils. It spreads enthusiastically, expanding via straggly runners. It has quite distinctive hairy stems and serrated green leaves, that are bright purple underneath. It can cope with frost if it’s shaded by trees.
Plectranthus is listed in the National Pest Accord, so it can’t be propagated, planted or grown for sale.
For small infestations, it's possible to manually remove the weed from the ground. Make sure all parts of the plant are removed, or it will reshoot. Burn the foliage, don’t dispose of it in green waste bins.
If a spray is required, use Yates Zero Tough. Apply to actively growing plants, spraying all foliage until just wet.
You can also use Yates Zero Super Concentrate in combination with Yates Pulse Penetrant to control Plectranthus.
Repeat treatments may be required if the weed has reappeared within 3-6 months.
