We are mostly left to work in our gardens and grow our plants unfettered by the huge bureaucratic monsters that clutter up other parts of our existence. Occasionally though they remind us that we are not forgotten, and find something they think we are doing wrong. Two plants that we grow have now been banned by the National Pest Plant Accord.
‘For New Zealand to be able to trade internationally, The Ministry of Primary Industries (MPI) must be confident that the products associated with agriculture, horticulture, aquaculture and apiculture are free from unwanted pests and diseases.
The National Pest Plant Accord (NPPA) is a cooperative agreement between the Nursery and Garden Industry Association, regional councils and government departments with biosecurity responsibilities.
All plants on the NPPA are unwanted organisms under the Biosecurity Act 1993. These plants cannot be sold, propagated or distributed in New Zealand.’
Plants are often put on this list to prevent their spread into our native bush where they may compete successfully with the existing ecosystems.
This Cestrum is frost tender for most of the South Island, and I have never seen seedlings come up, but in the North it perhaps could become quite a pest. It does have the most divine exotic perfume in the warm summer evenings.
As beautiful and deliciously fragrant as this Clerodendron is, I have to admit it can be rather a beast. I do see lovely trees in gardens growing most politely, but at my place it has suckered. I will miss it though, I do not know another plant quite like it.
My new solution to this problem I think must be to start saving so we can visit these foreign unwanted plants in their own environment. Lets hope where they come from has not been cluttered up by some other country’s pests.
