New Zealand Gardener Plants

There's always a long list of reasons to grow indigenous plants, shrubs and trees. In New Zealand, gardeners are spoilt for evergreens and spiky plants. So what actually happens here?
Cordylines and FlaxesThe Politically Correct New Zealand Gardener sources only natives, and they must be natives which specifically grow in exactly that part of the country. But then a country's greatest plant joys (and biggest plant mistakes) come in from the outside. New Zealand gardeners often try to combine the best of all gardening worlds.
Moosey's Potted History of New Zealand Gardening
New Zealand has the British Empire to thank (aargh!) for gorse and broom (and sparrows and rabbits). And later, English speaking immigrant gardeners brought in cottage garden plants (and weeds), rows of standard hybrid tea roses, the compulsory small garden's spring shrub collection - one Forsythia, one Camellia, one Philadelphus, one Lilac...
Cloud Farm SignGreen and Textural
While the New Zealand native bush is out there - splendidly green, splendidly textural, and splendidly non-coniferous. There are evergreens of every size and stature, every size and shape of leaf, and occasionally some pretty flowers. And so many amazing spiky plants - Astelias, flaxes, Cordylines, Libertias, tussock grasses, Pampas grasses...
Cloud Farm
A gardener I visited recently has deliberately decided to plant only native New Zealand plants. She's an environmentalist, looking after the regeneration of native bush-forest, and running a property off the main electricity grid. It's high on Banks Peninsula above Akaroa, and is called (appropriately) Cloud Farm.
Her patches of bush contain many healthy Totara trees - the Peninsula used to be heavily forested, but the ancient trees were taken for timber. Lots of broadleaf evergreens fill the understory. Her 'ornamental' gardens by the cottage are full of spikes - Cordylines, Astelias, Phormiums and different native grasses. Hebes live in pots, as does a Kowhai tree, and there's a lovely swathe of Celmisias, which the gardener calls 'Akaroa daisies'.
Grasses in the House GardenGrasses
Lots of paths zig-zag up and down the hillsides. They're well constructed for the wobbly visitor, weed-matted and laid with coarse chippy gravel, with lots of grasses to swoosh past. Just a few potted white pelargoniums and blue Petunias give tiny patches of colour, and the garden is full of rustic sculptural relics - as well as more modern pieces.
Garden Seats
And seats! Lovely garden seats, with dreamy views of the distant ocean (and often, I suspect, the immediate fog!) The old cottage has been marvellously restored, and the property has a rustic composting toilet (I want one), a 'shed with a bed' (nice - I want one of these, too), and character fences made of manuka branches.
