HOME gardeners should be on the lookout for the parasitic weed known as golden dodder.
Horticultural and hay producers have also been put on alert.
The Department of Agriculture and Food recently received a report from a gardener that the destructive weed had appeared among seedlings several months after they were purchased from a gardening centre and planted in a Perth suburban garden.
Department biosecurity research officer Sandy Lloyd said it was likely the golden dodder seeds had arrived with the seedlings.
“The seeds of golden dodder can survive for up to five years in soil until conditions are favourable for germination,” she said.
“The plant grows best in areas with high rainfall and commonly appears under irrigation.”
Golden dodder has smooth, thread-like stems about one millimetre thick. It is also known as ‘angel’s hair’ because of its appearance.
The stems twine around host plants and are usually coloured orange-yellow.
The flowers are about three millimetres wide, ball-shaped and creamy white or pink.
