Disa bracteata South African Weed Orchid
Although quite small even by terrestrial orchid standards this little plant makes up for its lack of height by multiplying quickly enough to be regarded as invasive. Glycophosphate is the recommended spot treatment to kill these little aliens and it is the first time I have heard of an orchid being so prolific an introduction as to warrant treatment as an invasive species. From its origins as a native of Cape Province in South Africa, it has now established itself in south Western Australia, South Australia, Victoria and has been reported from Tasmania. The typical orchid tubers which develop quickly make it difficult to eradicate and it can take over areas of bush and reduce the numbers of native plants as a result.
It is common from Perth down to Albany and inland but becomes less common towards Esperance.
