Our worst weeds

After advocating for wildflowers on our road verges in January, it is perhaps ironic that I follow up with the worst weeds in our garden. All are ornamental garden escapes and none should be liberated to roadsides.

Cape Pond Weed

Cape Pond Weed

There are times Mark has wanted to line up and shoot the former neighbour upstream from us who deliberately planted Cape Pond Weed – also known as water hawthorn, botanically Aponogetum distachyum. Pretty it may be in bloom, but we have been waging war on it for well over a decade. Floods scoured it out upstream but it has made itself right at home in our slow moving sections. We spend countless hours raking it out each summer because it we don’t, it will only take one full season before it covers the entire water surface. Miss one piece and it grows away again at an alarming speed.

Prunus campanulata filled with tui

Prunus campanulata ranks amongst our two worst weeds. We are constantly pulling seedlings out, or digging if they have snuck through to a second season. Any older than that, and they require poisoning. Yes I know some folk think we should get rid of all of these but the tui! The tui! And please do not tell me to plant kowhai for the tui instead because they don’t flower at the same time and even our largest kowhai trees cannot sustain the scores of tui that frequent our early blooming Taiwanese cherries. So we continue to deal to the unwanted seedlings on an ongoing basis.

There is hope. Mark has been turning his attention to the sterile campanulatas we have here, because it is the seed that is the problem. His father bred sterile campanulata hybrids – ‘Pink Clouds’, ‘Mimosa’ and ‘Petite Pink’. The last variety is probably not commercially available now which is a pity because it is a true dwarf tree. The problem with all three varieties is that they are candy pink, not the sought after carmine red. But we have a few sterile reds with some possible options which give flower power and nectar for the tui without the curse of seed.

About the bangalow palm's seeding ways...

About the bangalow palm’s seeding ways…

The other shocker – maybe I had better whisper this, given its popularity – is the bangalow palm (Archontophoenix cunninghamiana). Yes it is handsome and reliable but this Aussie import is far too keen to make itself at home. It took a long time for our specimens to start flowering but boy, are they a problem now. Mark tries to cut the seed off as soon as it is visible, but this requires the extension ladder and a pole saw. There is probably not a square metre left in our garden where we have yet to find a germinating bangalow. What is particularly concerning is that in the early stages, they are very difficult to pick apart from seedling nikaus. If you are anywhere near native bush or reserve, this is one plant that you should question having in your garden. Based on our personal experience, we recommend the Queen Palm (Syagrus romanzoffiana) as an alternative.

Mark adds in Cornus capitata, the weedy dogwood. It was favoured by his father who planted it all along one of the road frontages and Mark has been battling it ever since. At least it makes good fire wood.

Fuchsia boliviana performs TOO enthusiastically in our climate

Fuchsia boliviana performs TOO enthusiastically in our climate

We have reviewed pretty Fuchsia boliviana. We acquired it before it appeared on the National Plant Pest Accord but never moved it into the garden. Thank goodness. In the wilds of the “plant out” area, where some specimens can languish for years while waiting for the right spot to be found, it grew far too vigorously and the carpet of seedlings rang loud alarm bells. It is another of those plants where a sterile form would be advantageous because it flowers for months on end, is showy and has attractive foliage.

Dare I mention the wonderfully fragrant Himalayan Daphne bholua? It is not in the same league as the previous plants but it has certainly seeded down all round the place here. Not all the seedlings flower, either, which is not to their credit. It is another example of a plant which is highly prized internationally but can become a significant weed in our benign climate.

It can be a mighty fine line between a desirable self-seeder and a weed. Most of the plants mentioned produce berry-like seeds which are then distributed by the birds, particularly the kereru. Plants which only seed down close to the parent are manageable but once our feathered friends are on the loose, it becomes a different matter altogether.

Plant Collector: Fuchsia boliviana

Rewarding but a weed here - Fuchsia boliviana

Rewarding but a weed here – Fuchsia boliviana

“You can’t write that up,” Mark protested when he saw me photographing this plant. “It’s a weed.” This may be the first Plant Uncollector. We have had the plant for several years but it has never made it out of the nursery, being left to its own devices in the somewhat wild area of plants waiting to be put in the garden but not urgent. There it has seeded down freely and it won’t be going out to the garden because we can see it has serious weed potential. This is a shame because it flowers pretty much all the time and the hanging clusters are showy, while the foliage is velvety to touch. Our neglected parent plant is about 3m high and a somewhat rangy shrub but it can get bigger.

This is a variable species. There are red and pink, even and pure white forms. It is South American – not just Bolivia but also southern Peru and northern Argentina so presumably parts of Chile too. It is highly prized internationally but it will be somewhat frost tender which may curb its escaping tendencies in colder climates. We have enough imported weeds in this country. Just because it is attractive and has rewarding blooming habits is not a good enough reason to knowingly unleash another weed. This plant, along with its multitude of seedlings, is destined for the mulcher and compost. The seeds are spread by birds and because the plant can establish in heavy shade, it has a wide habitat. It is on the National Pest Plant Accord so can’t be sold legally but we arrived at the conclusion of its weed pest potential all of our own accord. If there is ever a sterile version of this plant released, we would welcome it but until then, no.
