Peter Butler

Plant fiend

29 Sep 26/in Farming and Horticulture, Features, Free Online, Magazine Articles

Plants of all sorts play their parts in this lively memoir by Peter Butler – from the plants that led to his imprisonment, to those he’s planted for income, enjoyment, or carbon sinks.

Butler is an entrepreneur with a zest for life, and an ebullient raconteur.

The HealthPost Nature Trust volunteers have just named their feistiest new fluttering shearwater chick, Butler, after me. It’s the one that fights and pecks at feeding time. These burrowing seabirds are not rare, but have been able to breed only on offshore islands since mammalian predators were introduced to New Zealand.

Our charitable trust is trans­locating and hand-feeding chicks to re-establish the first colony back on the mainland, within the Wharariki Ecosanctuary, at Cape Farewell on the west coast of Golden Bay.

It’s not a compliment to be named after this scrappy bird; I’m not proud of these traits reflected in me, but I’ve learned to accept and even use them. When my mother gave birth to my younger brother, she wor­ried that she wouldn’t be able to survive another one like me – but he turned out not to be the sort of pre-schooler she needed to tie to the clothesline pole. I was a bit feral – I chopped the hair off my sister’s favourite doll and learned to catch bees in my cupped hands without getting stung. Who knows where these characteristics come from? I was born with the umbilical cord around my neck – a reasonably common thing but apparently I went blue, and it was touch and go. Perhaps this contributed to me approaching life as a challenge.

Plants are my solace, silent companions that emanate calm. I like to be around them, look at them, taste their flavours, breath the oxygen they produce, inhale their various scents. Just like a crowd of people, a crowd of plants has a collective smell – there will be the odd flower that layers its whiff over the crowd, just like a woman with a loud perfume. You can usually pick the woman, but the plant can be nondescript, such as māhoe (whiteywood), whose strong-smelling little cream flowers emerge directly from its branches.

After rain, you can enjoy the rich, dark smell of all the composting (rotting, if you must) that has been catalysed by the moisture. It’s the musk of fungi breathing and insects farting. We all know the pleasure of walking beneath trees on a hot day – and it’s not just the shade but also the quality of the enriched air that gives us a lift. The biophilia theory, that humans have an intrinsic need to connect with nature, and plants in particular, for physiological well-being, has been repeatedly established through simple experiments.

This search for solace through working with, or being in the com­pany of, plants and the wild is a theme that has run through my life. The hills surrounding the Maitai River in Nelson were my early teen­age playground. I attended a secondary school with a lodge set in beech forest surrounded by mountains, where bands of boys were trusted to explore. The keenest of us organised our own multiday tramping trips. Always hard, always exhilarating. And then escaping the claus­trophobia of university in Christchurch was as simple as taking my books across the road to the magnificent botanical gardens. Working holidays were in a Queenstown that had not yet been crammed with tourists and millionaires.

My stuttering attempts at a creative career in Auckland were substi­tuted for life on a remote bush block in Golden Bay, track-making for the Forest Service and mining for gold. I experimented with lots of different crops in an attempt to make a living off the best of our dirt, spending decades developing the world’s only horopito farm, and in every visit back to that farm I still experience infusions of exquisite calm.

Now there is Nature Trust, which is a bit like work, quite hard at times, but our eco­sanctuary, high on the cliffs of Cape Farewell, feels like a Noah’s Ark, and we’re working to transform Farewell Spit into a Garden of Eden.


Author bio

Peter Butler grew up in Timaru and studied Political Science and History at the University of Canterbury before moving to a remote forest in Nelson’s Golden Bay. There, he threw himself into entrepreneurial activities, not all of which were successful. However, his relentless determination paid off with the creation of highly regarded natural health companies Forest Herbs Research and HealthPost.

Beyond horticultural and business activities, Butler has produced a feature documentary and written four books. He is now passionately engaged in improving the biodiversity of the Wharariki Farewell Spit area as chair of HealthPost Nature Trust. His memoir, Plant Fiend, chronicles his audacious, colourful life.

Azadirachta indica - the neem tree

Neem: Nature’s healing gift to humanity

Book review by Katherine Smith

It’s appropriate that the cover of this book features its author, Klaus Ferlow, standing beside a neem tree, his left arm reaching around to embrace its trunk in a fraternal greeting. That’s because Ferlow (originally from Germany) helped to introduce people in North America to the healing properties of the neem tree, after emigrating to Canada in 1975 and founding Ferlow Botanicals approximately 20 years later.

Klaus Ferlow credits his (now late) wife Rose with introducing him to neem by urging him to watch a TV programme called ‘What’s in a Neem’, narrated by David Suzuki. Inspired by the documentary, Ferlow obtained some neem extract and applied a neem cream to the psoriasis on his scalp and elbow and got relief from this condition in just three weeks. Having previously trained as a herbalist, he decided to set up a business to bring the benefits of neem to the North American market. Ferlow Botanicals is now rum by the Ferlows’ sons, Peter and Harald, and Ruth (Peter’s wife).

Klaus Ferlow has maintained his interest in neem and founded the organisation Neem Research “to promote neem for human, animal and environmental health”. His new book, Neem: Nature’s healing gift to humanity, includes profiles of neem researchers and entrepreneurs. He gives special credit to the late Professor Dr. Heinrich Schmutterer as ‘the father of modern neem’. It was his observation that neem trees had survived a plague of locusts that swept through Sudan when he was on a field trip there in 1959 that caused him to wonder if a natural insect repellent could be present that led to his work researching neem and writing the definitive textbook on neem, The Neem Tree (1995, 893 pages).

From the home of the neem tree in India, knowledge about the tree has spread to North and South America, the Caribbean, Africa and Australia.

Among the examples described in the book is Abaco Neem, a farm in the Bahamas that includes neem trees intercropped with fruit trees. (In all, 120 varieties of fruiting and flowering trees are grown on the farm.) Spiders and beneficial insects like butterflies and bees have thrived in this environment and hives on the farm allow neem honey to be produced as well as other neem-based health and personal care products. Some of these products incorporate beeswax from the hives. Among the products produced by Abaco Neem is a neem-based insect repellent.

The farm has organic certification and the fruit from the neem trees also has the benefit of providing food for birds; a visiting intern from France identified almost 40 different bird species on a single day.

In addition to being used to promote human health when used as a supplement or medicine, neem has the potential to boost food production. Neem extracts can be used as insecticides and ‘neem cake’ made from defatted neem seeds can be used as a fertiliser that also helps to protect plants from nematodes. The book also reports that a constituent of neem (azadirachtin) is being developed as a food additive for farmed salmon in Scotland to treat sea lice infestation of the fish.

In India, a company called Nisarga Biotech has been producing supercritical extracts of neem (using CO2 to extract constituents from the plant) which may be used as botanical pesticides, or in cosmetics or personal or medicinal products. Their product line includes a neem toothpaste and mouthwash – a modern iteration of the tradition in Indian villages of using neem twigs as a toothbrush. The company has also ‘secured a patent for the manufacture of neem leaf CO2 extract for use in treating oral and colon cancer’.

Neem: Nature’s Healing Gift to Humanity is a testament to the hard work and vision of its author and all the individuals whose businesses feature in its pages.
