The New Zealand government must take “more rigorous action” to work with the horticulture industry to stop the spread of invasive garden plants, says a leading ecologist.
Lincoln University biosecurity professor Philip Hulme wants a more coordinated approach to assessing the weed risks of garden plants before they are imported, grown and widely sold as ornamentals.
Common garden plants that have become destructive weeds in NZ include buddleia, English ivy, honeysuckle and jasmine.
