1) No fewer than 700 Higo iris waiting to be planted out in Plant Collector this week.
2) Yet another joint venture infomercial masquerading as a reputable garden reference book – the Tui NZ Flower Garden this time.
3) The current quest for self sufficiency, of sorts at least. More a measure of a high quality of life here than a point of principle – Abbie’s column.
4) Grow it Yourself – rhubarb this week.
5) And absolutely nothing to do with gardening but a link to my other website (www.runningfurs.com) where I publish book reviews of a non gardening nature (mostly cookbooks, children’s literature and a bit of adult fiction) – the latest of which was indeed a cookbook: The Molten Cookbook by Michael Van de Elzen. Food porn, my chef friend calls it.

Inspired by Hidcote - the white foxgloves
Inspired by Hidcote – the white foxgloves

At last the temperatures are rising and it feels as if we may be on the cusp of summer after all. The tall white foxgloves have been bringing me much pleasure, simple though they are. We saw these used to great effect at Hidcote Manor in England but, being a biennial, it has taken eighteen months to get them performing here. I am hoping they will seed down as readily as their pink counterparts (most of which are being consigned to the compost to try and keep the white strain pure).

Sparrows in the Queen Palm condo

Sparrows in the Queen Palm condo

We have been somewhat amazed in recent weeks watching the entire condominium of nesting birds in the crown of the Queen Palm (Syagrus romanzoffiana) – they must be fifteen metres up and it appears that every nesting space is occupied. The dominant population is sparrows with the odd starling having made a move on vacant property. As we sit in our favourite conversation spot, we look out at the many comings and goings, while the tui nesting in the nearby rimu attempts to patrol the entire area and convince all other birds that they are deeply unwelcome.

The celmisia in flower is a reminder to me of the next website project – building the record of native plants we have in the garden. This is of less interest to New Zealanders who tend to fall into one of two camps – the dedicated purist (natives only) and the rather dismissive (“natives are so boring”). In fact, we use many native plants in the garden but interspersed with exotics. I read an opinion recently that the use of native plants is an important way of anchoring a garden into its environment and its country of origin, which seemed to make good sense.

Plant Collector – Higo Iris

Remarkable seedling variation in the Higo Iris

Remarkable seedling variation in the Higo Iris


We are particularly delighted with the Higo irises at the moment, all 700 of them which are in small pots in the nursery awaiting planting out. These are often called the Japanese water iris because they are happy to live in pretty soggy situations.

Unravelling the family tree of Higo is not straightforward. Japanese water iris all descend from I.ensata but around 500 years of breeding has seen different strains developed – Edo, Higo and Ise. Many of these hybrids resulted from a search for perfection in a single bloom, to be brought indoors and contemplated as a transient thing of beauty. This does not necessarily make for garden plants. Mark had tried some large flowered Higos in the past and not had success with them. Not only did the blooms weather damage too readily for our climate, the plants could not cope with anything other than optimal conditions in very well cultivated soil.

Wanting a strain which is closer to the original species and therefore likely to have smaller flowers and maybe a more robust nature, Mark was delighted when Auckland plantsman, Terry Hatch, offered him a tray of plants reputedly derived from wild collected seed. It has taken a little effort to pot on the plants and grow them to flowering size but this spring it has all been worth it. There is a huge range of flower size, markings and colourings coming through in the plants though we doubt that they are anywhere close to the original species which grew in the marshes near Tokyo 500 years ago.

Most of the 700 are destined for planting in swathes on the margins of our ponds and stream though I shall get down on a few and experiment with growing them in garden borders. The critical issue appears to be ensuring that they never dry out completely.

The Tui NZ Flower Garden by Rachel Vogan

Tui NZ Flower GardenSigh. Another joint venture infomercial from Penguin Books and Tui Garden Products whereby you, the customer, get to pay about $50 to be told what Tui products you need to buy in order to grow lovely flowers like the ones in the photographs. That is about it in a nutshell. On the plus side, this book does at least have an index and, hallelujah, it actually gives the botanical names in small print of the main plant families. It is just a shame that neither author nor editor understand the conventions of plant nomenclature. Common nouns like daffodil, magnolia, lily and bluebell do not have a capital letter every time they are used.

The bulk of the book is alphabetical listings of flowering plants (trees, shrubs, climbers, bulbs, perennials, annuals – yes, apparently you can cover the greater part of the plant kingdom in just one book) and it appears completely random as to whether the plant will be listed under its botanical name or its common name. Recommended varieties are equally random.

I am afraid the author lost us when we read the page on magnolias. It was bad enough to mislabel a photo of our Magnolia Vulcan as Genie, let alone misspell our famed Magnolia Iolanthe as Lolanthe but when we got to read that the evergreen Magnolia Little Gem is a small growing form of the aforementioned deciduous Lolanthe, we threw our hands up in despair. And we have actually managed to grow quite a few magnolias here without planting them into Tui Garden Mix and fertilising them each year with Novatec.

When the recommendation came that you plant anigozanthus (kangaroo paws – Australian plant that thrives in marginal desert conditions) with Saturaid, we worried about the advocacy for routine use of a soil wetting agent. There is no faster way to kill a woody plant or a dry loving plant in humid areas with high rainfall.

By the way, Penguin, it is time you dispensed with the auto spellchecker. The author of this book winning prizes for exhibiting her Gladys rivals a previous author counselling readers to throw out their Algarve. The author may have been using the colloquial term of gladdies, but even that is inappropriate for the text on page 164 and 165 where poor Gladys has her name taken in vain repeatedly. Gladiolus stands for one, gladioli for more than one. Gladdie is the vernacular, not the common name. Gladys is somebody’s grandmother.

Otherwise, it is a typical Penguin/Tui book which sits alongside its three sister volumes on vegetables, kid’s gardening and the infamous fruit one. I am hoping they have called it a day and don’t plan to inflict further volumes (maybe on organics or natives?) on the buying public.

A mast year for strawberries in the quest for semi self sufficiency here

It appears to be a mast year for strawberries here. That is a term for when plants produce a significant abundance of fruit. In nature this can be important. Apparently kakapo need rimu to have a mast year in order to breed. But here it just means we are having a bumper strawberry harvest. Not wanting to overstate the case, but they are coming in by the bowl full.

This leads me to the issue of self sufficiency and the observation that if you want to be self sufficient, you have to accept that there will be mast years and there will be famine years for some crops. At least we have the supermarket option these days so the famine stakes are not as high. I have noticed that self sufficiency has become trendy again, often espoused by people who claim that it is terribly easy and achievable in very small areas, taking relatively little time. All I can say is that self sufficiency must mean different things to different people and varying levels of home provision are being hailed as self sufficiency.

We describe ourselves as relatively self sufficient in fruit and vegetables. We produce enough fruit for high individual consumption all year and only buy additional fruit for variation in the diet and seasonal treats which cannot be grown successfully in our area. We generally produce sufficient vegetables but there are times we have to supplement. The husband felt such a failure when I had to buy a bag of potatoes last week because we had run out of old ones and we had eaten the first crop of early ones already. The onion harvest was poor this year so we have had to buy. Purists would maybe go without onions for the year.

But we are nowhere near self sufficient if you take in grains and animal protein. We don’t even attempt to produce our own grains. While we raise our own beef, we haven’t done our own poultry for years. To be genuinely self sufficient, you would need to factor in sufficient grain cropping to be able to feed the poultry as well.

Nevertheless, it is astonishing quite how much area gets taken up in providing sufficient to keep us going at the level we like for just the two of us and how much time it takes on the part of He Who Produces it All (aka Mark). Fortunately he enjoys doing it. If it was left to me, it would be a poor harvest of basil and lettuces at best because I would rather grow flowers. Mark has long scoffed at suggestions that you can achieve self sufficiency in a tiny plot and in dinky raised beds so we returned to The Oracle to see how much land she thought was needed. The Oracle is Kay Baxter, founder of the Koanga Institute. She only preaches what she practices and she has close to 40 years of experience in food production, organics and self sufficiency. We have the utmost respect for her opinion. According to her: “To grow all your veges and grains, you will need 100 square metres per person.” Yes that does include grains, which not many of us produce, but it does not include fruit. That is a hundred square metres of healthy soils in full sun with good shelter – per person. For a family of five – five plots of 10 metres by 10 metres. There are reasons why modern society has turned to the industrialisation of food production and one is the economies of scale.

If you want to produce your food on organic principles, you may need an even greater area. Generally speaking, organic production relies on producing crops at optimum times and not pushing the boundaries either end of the season (because that is when pests and diseases will strike more readily). You also need to be meticulous on crop rotation and soil management because you don’t have the fall back position of a chemical arsenal to rectify problems.

Factor in time as well. Time every week, not just when the gardening bug strikes in spring. To get reliable production in the vegetable garden requires constant vigilance, planning and regular work. If we costed in our time, it would be cheaper for most of us to buy all our food.

For us, it is a measure of a very high standard of living that we can produce most of our fruit and vegetable requirements. It is not a point of principle so much as a measure of quality – quality of both produce and life. When our lives were more frenetic and we had the demands of running a seven day business, there was not the luxury of time to produce food which could be bought cheaper and more conveniently from the local shops. There can be luxury in simplicity. Just don’t believe the current advice that you, too, can be self sufficient in fruit and veg in next to no time with minimal area and effort and it is all wonderfully simple. Ask such proponents again in twenty years time and you may be told something very different.

Grow it Yourself: Rhubarb

Rhubarb is one of the few long term plants in the vegetable garden. A clump can last anything up to 10 years, though if you are a rhubarb fan, you are more likely to be renewing your patch more regularly than that to ensure uninterrupted supply. Think of it like a clumping perennial – it grows from a crown below the surface of the ground and makes its own offshoots. Like most perennials, it likes to be planted in ground that has been well dug over with plenty of humus or compost added in. Beyond that, it does not want wet feet in winter (which will kill it) and it is fine in half to full sun. Just feed it or mulch with compost once a year – spring is a good time. An established plant is going to take anything up to a round metre is space (that is, as opposed to a square metre).

Usually the pinker the stem, the nicer they are to eat but apparently there are varieties that stay green so you may be waiting forever with them. The leaves and roots are poisonous because they contain oxalic acid so you do not want to eat them or to eat the closest stem parts. However it is an urban myth that it is not safe to put them in the compost heap. I have yet to meet anyone who eats their compost and the natural toxins break down in the composting process.

It is easy to grow rhubarb but it is only worth the effort if you like its taste and are prepared to cook with it. I like to add a little gelatine to my stewed rhubarb, being a jelly fan. Adding a little grated fresh ginger while cooking takes it up more than one notch and I found the children ate it quite happily when it was cooked with some sago added (check out Alison Holst’s recipes).
