Tropical paradise

We all want to create our little corner of paradise in our gardens and it’s fair enough that Kiwis look to the tropics for inspiration, after all, most of us have had a memorable South Pacific or north Queensland holiday.

The bad news is that we live in the sub-tropics which means we can’t have a true “tropical” garden as it’s not only about temperatures and rainfall but the almost unvarying levels of daylight through the year nearer the Equator.

Palms are the backbone of any tropical garden and while we can’t grow the coconut palms so typical of an island paradise, we do have access to a range of trees to suit our climate.The good news is we can achieve “tropical-look” gardens if we do our homework and are clever about plant choice.

Layers of planting – canopy, sub-canopy, under-storey and groundcover – creates depth and gives the impression that a garden is bigger than it actually is.

Large trees and plants include Parajubaea cocoides (Quito mountain coconut palm) that can handle strong winds and hard frosts; Chatham Islands nikau, Rhopalostylis sapida; Atherton palm (Laccospadix australasica) from Lord Howe Island (not below minus 2C); the fish-tail palms Caryota ochlandra and C.obtusa; the smaller Dipsis boroni (hardy sugar cane palm); Strelitzia nicolai (giant bird of paradise, looks like a banana palm); banana palms; and Meryta sinclairii (puka) which although frost tender, can be grown in shade.

In the display garden at Palmco in Kerikeri they have created a coconut palm effect by planting bangalow palms on an angle – as the trees straighten up and grow towards the light a bend develops in the trunk.

Other plants to help the island paradise feel include hibiscus, bromeliads, taro, gardenias, day-lilies, rengarenga lilies, Chatham Island forget-me-nots, hostas, pineapple lilies (eucomis), canna lilies, vireya rhododendrons, star jasmine, orange jessamine (Murraya paniculata), cymbidium orchids, hoya and clivia.Smaller hardy orchids, such as Australian Dendrobiums or Zygopetalums, can be grown on trees or in ponga posts.

Ferns and tree ferns also add to the tropical look and are relatively easy to source.

If you don’t have room for a pond, water lilies can be grown in a half-barrel or a large, glazed pot.

And don’t omit bamboo from your line-up just because of its weedy reputation. Choose carefully and it will add a grace to your garden that few other plants can achieve.

Robin Booth of Wharepuke garden in Kerikeri finds that once an area is planted, plants create their own micro-climate and “support one another”.

He imported Cordyline fruticosa Fiji in to New Zealand “many years ago” and says the small tree with its brightly coloured leaves will do well in a cooler climate. New Zealand grass trees (Dracophyllum) are another shrub-size alternative.

Going bananas

Yakking to David Harricks in his Greerton garden yesterday (his efforts at sustainability will be featured in next Saturday’s Bay of Plenty Times) and spotted a young banana tree – a Blue Java variety, also known as the ice-cream banana because of its texture and flavour.

David got the tree from Rodger Bodle of Gisborne and he told me a bit about Rodger’s pioneering work with bananas. This interview with Rodger is from 2011. Please note that Rodger sold his garden in 2015.

Rodger has been working with bananas since the 1950s and says his biggest bunch to date has been 15kg of the Pesang variety from Indonesia, a tree that has acclimatised to his conditions. He calls his garden Bermuda Palms Banana Research and believes it is the southernmost banana research station in the world.

His garden is home to varieties from Fiji, Samoa, Ecuador, Brazil and Israel, and he also has outdoor plantings of pineapple, coffee and orchids.

Email Rodger or find him on Facebook.

Welcome inn

Guests at Katikati Motel are able to pick fresh organic fruit and vegetables from a new garden – and are then asked to recycle their food scraps to the chickens or worms in a closed-loop fertiliser system.

But when Kate and Kent Pfenning bought the motel a year ago, the garden was an area they called their “problem child”.

“It used to be an old swimming pool,” says Auckland-born Kate. “But it was filled in years ago, planted and walked away from.

“We thought we’d like it as a produce garden but it was physically too overwhelming as to how we could convert it.”

The couple saw a newsletter about a local permablitz and thought the programme based on the principles of permaculture might meet their needs.

Unfortunately, Kent had farm commitments to meet and flew back to his native North Dakota in the United States the week before the working bee, but Kate decided to go along and was impressed with the camaraderie. “I didn’t know anyone but it all just clicked,” she says.

Before their permablitz last October Kent and one of the local co-ordinators, Hugo Verhagen, broke up the concrete path that had been round the pool and built raised beds and a pergola.

The beds have been designed so the chicken coop fits over them, leaving the hens (which came with the property) to clean up, till and fertilise a bed at a time. There is also a compost heap and worm farm.

The garden is bursting with food, including herbs, cucumbers, tomatoes, potatoes, yams, kumara, beans, broccoli, cabbage, carrots, lettuce, grapes, passionfruit, citrus, raspberries and strawberries.

 

Kent is a third-generation farmer and, since their marriage 18 years ago, Kate has worked with him, raising beef, sheep and crops on a property near the border with Canada.

Until their move to New Zealand with their three school-age sons, Kate had her own business supplying lamb to the restaurant trade.

The couple moved to New Zealand to be closer to Kate’s parents and settled on the motel business having been “frequent receivers of motel hospitality”, she says.

“We may not know the motel business very well but we know business so we were confident we could make it work.”

However, the couple couldn’t have afforded to make the garden they now have, courtesy of like-minded people.

“We’re trying to turn the garden into a working business concept – everyone in the motel trade is selling sleep so this is our point of difference.

“People are delighted when I say they can go and help themselves and do they want some eggs too?”

Thursday digest

Orchid lovers are flocking to Kew this month for the annual Orchid Extravaganza, which includes a whole wall of vanda flowers. Read more here and see a photo gallery here.

I’ve recently joined the writing team at the GardenDrum website, run out of Australia by Catherine Stewart. It features a wide and diverse bunch of writers so there should be something to take your fancy. So far, Rose Thodey of Auckland is the only other Kiwi writer but Catherine hopes to add more soon.

Ever wondered about “no-dig” gardening? It sounds too good to be true, but here’s a whole blog devoted to it, courtesy of a Wellington gardener who established her first no-dig garden in England “a while ago”. Heaps of useful and practical advice.

Robin Booth has been planting and tending his Kerikeri garden since 1993 – and stuffing it full of interesting tropical and sub-tropical plants that you won’t see too many other places. We visited Wharepuke in the winter of 2011 and discovered that as well as the delicious garden there is also an award-winning cafe which is beautifully situated on the edge of the garden. Well worth the trek north. Robin, by the way, is the brother of “environmental sculptor” Chris Booth.

A huge project is under way to reveal André Le Nôtre’s original vision for Louis XIV’s Petit Parc at Versailles. Read more about that here.

Wine-making course

Colin Hewens at Whakamarama is getting ready to share his expertise in using garden produce to create wine.

He says a glut of feijoas got him started on the wine-making trail back in 1976 – the resulting tipple wasn’t great so Colin decided to get it right and hone his skills. He’s previously taught night classes at Tauranga Boys’ College “starting in the chemistry lab and ending up at my home”.

“People usually turn their noses up at home-made wines because they have been bitten by some noxious brew in the past, but I give them a taste of what we make here and their eyes light up.”

Colin and his partner Steve will start their classes next month, one night a week for four consecutive weeks from 7.30pm for 2 hours. Participants will make three five-litre batches of fruit wine by different methods, and sample several cellared brews to see what the results can be like.

Interested? Phone Colin on (07) 552 771 or email him.

Flowering now

Yes, it’s been a long, hot summer and yes, the summer flowers are starting to struggle a bit but there’s still plenty going on in the garden.

The other day I heard someone say that Gaura lindheimeri is much-loved by butterflies. But I think she was confused by the plant’s common name of butterfly bush, which comes from the way the flowers move about, not that they are particularly attractive to butterflies.

For the past couple of years I have trained my plant up through a stake and hoop system (bought from The Warehouse) to stop the long stems flopping all over the place. The effect now is rather like an explosion of flowers.

In the past I have tried the more strongly coloured hybrids and found them to be short lived, while the original pale pink variety just goes on and on. I cut the plant – a North American wildflower – back to the ground when it starts to look past its best.

A few years ago a friend who was cleaning out an old garden to establish her own gave me some Amaryllis belladonna (naked lady) bulbs. Completely by accident I planted them in exactly the right place – full sun with good drainage. The strappy foliage is nice and lush, and the messy dying back period lasts only for a short while.

The flower, as the common name suggests, comes after the foliage so are “naked” on a single stem. Mine are all white flowers, but there are also pink-flowered ones. I once divided a large clump of bulbs but found they “sulked” for a year or so before coming back into flower.

Liriope muscari plants flower from summer into autumn and are good for a shady spot. The plants (they look like they might be bulbs, but aren’t) are easy to divide once they clump up and have a long flowering period. Locally, Ace Mondo offers a range of colours.

Ozbreed has developed Liriope Isabella, which the company promotes as an easy-care grass alternative for a lawn – it needs mowing only once a year!

Advance Australia fare

It was love at first sight for Colin Henderson when he went to Australia in 1966 to get married in the Blue Mountains west of Sydney. Already in love with bride Pat, he also fell in love with Australian flora.

“When I went to Australia I had assumed the only flora was gum trees. Every time I stepped out of the car I saw another interesting plant,” he says. “While gum trees or eucalyptus are dominant in the landscape, I quickly discovered a huge diversity of flora from tiny flowering plants and grasses to fantastic trees and shrubs with interesting flowers or bark or both.

“There are more plant species in the Hawkesbury sandstone area north of Sydney than in all the United Kingdom. Australia hosts 15,000 plant species of which only about 600 are actually gum trees.”

When Pat and Colin bought a home in Brisbane in 1968 they promptly dug up the lawn and created an Australian bush garden. Colin also joined the Society for Growing Australian Plants.

“I just got stuck in and learned by growing, and that was when I first discovered the value of mulching,” he says. “I used bark extensively and have used absolutely tonnes of it since.”

Colin, an accountant, and Pat moved to Tauranga in 1973 with the intention of establishing a specialist Australian plant nursery. Jarrah Park Nurseries was developed on what is now Twelve Acre Wood in Pyes Pa, the housing subdivision developed by Colin and Pat and where they still live.

Colin also helped run the Plant Wholesalers Group in the late 1980s and early 1990s from the property. The group combined the marketing arms of several Tauranga specialist nurseries and still operates. Colin’s involvement ended as his role as the area’s specialist school accountant grew.

Then, in 2002, while felling a tree in preparation for the Twelve Acre Wood subdivision, Colin had a serious accident which resulted in the amputation of his left leg.

“You can usually find some positive outcomes from adversity,” he says. “I was advised that I shouldn’t work for six months at least. Convalescence gave me the time to focus on the Twelve Acre Wood development and I was able to preserve as much as possible of our Australian ‘landscape’ within the common parkland.”

Most of Colin and Pat’s own garden is in Australian natives, some of which are now well-known in New Zealand, such as grevillea, bottlebrush (Callistemon), kangaroo paw (Anigozanthos), bangalow palms (Archontrophoenix cunninghamiana) and banksias.

But they also have some rarities, including the black-bean tree (Castonospermum australe) with its bright orange flowers, Gymea lily (Doryanthes excelsa) and its soaring flower spikes, and the green-trunked tropical cadagi gum (Corymbia, formerly Eucalyptus, torelliana).

Castonospermum australe, the black-bean tree, flowers on old wood.

Several plants have surprisingly aromatic foliage with clean, sharp scents – grey mintbush (Prostanthena incana), lemon-scented myrtle (Backhousia citriodora) and lemon-scented ti-tree (Leptospermum citratum).

“It’s nice to have something surprising about a plant,” Colin says of his scented plants, “and there are a wealth of Australian plants in this category.”

Australian flora can generally withstand drought, and any with greyish foliage can handle salt-spray or wind. He has used bottlebrushes, including an unusual weeping variety, extensively in his private and public landscaping.

“They flower for long periods, are fodder for birds and bees, can handle any sort of condition and prune well.”

Colin’s favourite Australian plants are the paperbark gums (Melaleuca) which come in a variety of thick, soft, spongy barks, that peel from the tree and are traditionally used by Aborigines for building shelters, making hats, boats and containers for water and food.

“Because we were once a single land mass, many Australian native plants have relations in New Zealand,” Colin says, “especially if they are Tasmanian natives.”

The Australian ti-trees are related to our manuka, the blueberry ash (Elaeocarpus reticulatus) to the hinau, there is an Australian kauri and cordylines which are related to our cabbage tree, while plum pines (Podocarpus) are related to totara.

Most Australian plants flower from winter into spring and so set seed for a long, dry summer.

Our native plants: Cordyline

New Zealand can no longer boast of having the largest lily in the world – the cabbage tree (Cordyline australis, ti kouka) – as botanists have moved it into the asparagus family. The tree can be seen almost everywhere, particularly (but not only) in damp places.

I’ve been told that early settlers used the hollowed-out trunks of cabbage trees for their cottage chimneys because the trees are so resistant to fire, and now I’ve even read it on the DOC website, where there are several other interesting facts including that cabbage trees are one of the most widely cultivated of our native plants and are grown in Europe, Britain (where they are known as the Torquay palm) and the United States.

Parts of Cordyline australis are edible and Maori also used the fronds for weaving sandals and baskets.

The trees can grow to 9m or more and the plant will regenerate from a destroyed trunk, although since 1987 the trees have suffered from something known as Sudden Decline, believed to be a pathogen possibly transferred from tree to tree by the Australian passonvine hopper.

There are several other forms of cabbage tree, including Cordyline banksii, which has particularly large flowers, the small Cordyline pumilio (up to 1m high and across) and Cordyline indivisa (mountain cabbage tree – see an avenue of them at Larnach Castle, near Dunedin).

Watch out for two new roses being released by Rob Somerfield this year – Wild Cherry and Pacific Glory, a lavender-pink floribunda that is the official rose of Roses Down Under, the World Federation of the Rose Society Regional Convention in Palmerston North, from November 23-28.

A competition was held to name the convention rose with the winner announced at the national show in Levin last November –  Derrol and Helen White from the Northland Rose Society came up with Pacific Glory and received six roses bred by Rob as their prize. Coincidentally, the Whites won the Champion of Champions at the national show with White Romance, another Glenavon rose by Rob.

Pacific Glory won a Gold Star of the South Pacific (the top award) at the national trial grounds in Palmerston North in 2006, while Wild Cherry, a floribunda with vibrant red flowers, won a Certificate of Merit in 2011.

Garden centres will take orders now for roses to be delivered in the winter, the best time for planting them.

Added Feb 10: Villa Ridge garden centre at Tauriko has a printed Rose List for for 2013, including David Austin, hybrid teas, climbers and old-fashioned roses. Ph 07 543 1093.

Three new Jury magnolias will be available this year – Fairy Magnolia White, Fairy Magnolia Cream and Magnolia Honey Tulip (a yellow form of Black Tulip). Read about them and see pictures on the link.
