Asparagus drepanophyllus and A. umbellatus are twining vines with the potential to smother and strangle their host plant. These plants are relatively new introductions to New Zealand, having been imported illegally.
Asparagus drepanophyllus is leafless at flowering time. It's flowers are white or creamy with strong sickly odour. It has thorny stems.
Impacts in New Zealand are not quantified, however most exotic asparagus species have become serious environmental pests.
1. Report it immediately to the Auckland Council Biosecurity team, who will arrange for its control at their expense.
Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
