Windflower romance

Wind flowers are a personal marker of our wedding anniversary

Wind flowers are a personal marker of our wedding anniversary

On the evening before we married, Mark turned up with an armful of Japanese anemones that he had gathered from the Taihape roadside. Don’t even ask why we got married in Taihape when we neither lived there nor came from there. It’s a complicated story. Wind flowers, he called the anemones and believe me, although back in the mists of time, it was a romantic gesture I have never forgotten.

Every year the wind flowers bloom on our wedding anniversary and he often brings some indoors. Last week he followed the old cut flower wisdom – re-cut the stems and burned the ends and they have lasted a full week in water.

We have three different Japanese anemones, in light pink, white and a semi double dark pink which is more compact in growth. It seems that the first two are the straight species, A. hupehensis. Although known throughout the world as Japanese anemones, they are originally Chinese – from the eastern province of Hupeh, in fact. They have been grown so widely in Japan for so long that common parlance attributes them to that country. It is no surprise that the Japanese, with their cultural penchant for simplicity and natural form, took a liking to them.

The semi-double darker one will be a hybrid and a named form that was purchased. Mark commented vaguely that he thought it may carry a woman’s name but I see that this plant family is more highly prized overseas than in New Zealand and there are a fair number of named forms, several of them named after women. For the botanically inclined, the Japanese anemones classified as A. hybrida are likely to be mixes of A. hupehenis with A. elegans and A. vitifolia. This is a plant family that crosses readily – though to get a cross you generally need plants that flower around the same time.

Weeds, I hear some readers saying. Weeds. Yes they can be overly vigorous, given the right conditions and become rampant, bordering on invasive because they spread below ground. You probably don’t want to unleash them in areas with plant treasures which they may out-compete. Lovely though they are in flower, you can have too many of them.

That said, I see that there is general agreement that they are not always easy to establish which made me feel better about our meagre showing of white ones in the woodland garden. I had spotted a pretty patch down the road, growing as a roadside wild flower and it is those I photographed. I love the combination of the single, white flowers dancing above the dried grasses.

Our pink ones are planted on our roadside and come into flower after the summer colour has largely faded. We have designated our rural road verges no-spray zones with the local council so we carry out our own maintenance. We mow a grassy strip immediately beside the road, get rid of noxious weeds like the dreaded bristle grass and we can do what we like with the rest. And what we like are roadside wild flowers – agapanthus, hydrangeas, robust begonia species, oenothera (evening primrose), belladonnas, crocosmia and the like. It is not just for passing motorists. It is also to feed the bees and to keep some roadside cover in an intensive dairying area which can otherwise resemble a green grass desert.

There are actually somewhere over 120 different anemone species. By far the most common in gardens are A. coronaria. These are the spring flowering corms that you buy as de Caen (the singles, mainly in blue and red but also in pinks and whites) and St Brigid (the doubles). They are very cheerful and cheap to buy. If you get a bulk pack, split it into four and soak one batch at a time overnight before planting. Done at weekly intervals, you can extend the flowering for the first season.

A. blanda is a little Greek species with predominantly blue flowers, more like a carpet if mass planted. A. nemerosa is the European wood anemone. We would like both of these dainty species to naturalise far more widely in our garden than we have achieved so far. They are transient early spring delights.

But in autumn it is time for the wind flowers to star.

Outdoor Classroom: Layering plants

OLYMPUS DIGITAL CAMERA1) Some plants are difficult to propagate from cuttings, even more so for home gardeners without temperature and moisture controlled conditions. If you are not in a hurry, layering a plant can be a simple way of increasing numbers or of getting a back-up plant for rare or special material which may not be available for sale. This rhododendron has layered naturally where branches lie on the ground.
photo 22) The plant needs to have low growing, flexible branches which reach to the ground. You may wish to try layering plants such as magnolias, rhododendrons, camellias, daphnes or conifers. Most woody plants can be layered over time but it is faster to do easily propagated plants like hydrangeas from cuttings.
photo 33) Select a firm branch or stem which can reach to the ground. It does not matter how old the wood is though young growths from last season may root faster. Remove the leaves from the middle if necessary. Slice a thin layer of bark off the lower side (called making a wound). You can paint the wound with rooting hormone if you have it, but this is not critical.
photo 44) Cultivate a small area of ground beneath the branch or dig a small trench. Peg the branch down so the wound is in contact with the soil. A hoop of wire is ideal for this part of the process. Peg it firmly so it cannot move. Cover the pegged area with up to 10cm of soil. You want to prevent the layered stem from drying out. Leave the branch tip uncovered. Now be patient. It will take a year for easy material and maybe as long as three years for difficult to propagate plants such as many of the rhododendrons.
OLYMPUS DIGITAL CAMERA5) When the layer has formed a reasonable mass of roots, cut it from the parent plant (think of this as cutting the umbilical cord) and either let it grow a little longer where it is or move it to some well cultivated soil – the vegetable garden is often good – so you can take care of it while it develops into a more sturdy plant.
OLYMPUS DIGITAL CAMERA6) You will usually need to stake the plant to train it to grow upwards and to start developing a good shape although you can sometimes plant it on an angle to get the main leader almost vertical.

Continuing the quest to get to grips with perennials

Perennial beds at Auckland Botanic Gardens – white gaura with eupatorium and a salvia.

The January issue of the NZ Gardener magazine had a two page feature from Auckland garden designer, Xanthe White, on designing perennial borders. It is worth searching out if you are interested, because it is a remarkably succinct piece of writing tailored to in our conditions.

I say “our conditions” because gardening in this country is a year-round activity. In much colder climates, people put their gardens to bed for several months of the year and retreat indoors. I can’t recall any New Zealand garden I have seen which becomes a bare, dormant canvas in winter. Xanthe was suggesting getting a mix of perennial plants to take the garden through the seasons. Her recommended balance was to select 30% of plants that flowered in each of the peak seasons of spring, summer and autumn and 10% in winter. It is good advice, though you may be struggling to find a wide range of winter flowering perennials beyond bulbs and hellebores.

The trade-off is that there is never a peak time for bloom. Nobody does herbaceous borders like the English do but it is not just because of their labour intensive property that we have not embraced them in this country. Few New Zealand gardeners would accept a garden which looked absolutely amazing in February, pretty good in January and March, starting to pass over by April, dead as a dodo through the winter months and resolutely green with no colour in spring. But if you want a garden that comes together all at once in peak perfection, that is what you can end up with. To manage blooms and fresh growth for a much greater period of time, requires very high level gardening skills, plant knowledge and willing labour.

The fall back position in New Zealand is to add in trees and shrubs and to encase the border in a neat little evergreen hedge. Buxus suffruticosa was the go-to option for this until the dreaded box blight took hold. This takes it away from a perennial border and turns it into a mixed border. We all do it. It is rare to see a straight perennial border here, outside of public parks and botanic gardens, without woody shrubs, trees and hedges added in to give year round structure and interest.

When it comes to understanding perennials, I would ever so modestly claim that we have a better than average knowledge of bulbs and woodland or shade perennials here. Getting to grips with perennials for sunny positions is a different kettle of fish altogether. Several years in already, I can see that it is likely to take the rest of my active gardening life to get the level of knowledge and skill I want. They are the mainstay of the summer garden and a major contributor to the autumn garden but my goodness it can be complex. I disregard spring because, honestly, we do brilliant spring gardens in this country. I see lots of splendid gardens filled with colour, lush foliage and scent throughout spring time. It is easy here. But I can’t recall seeing drop-dead wonderful summer gardens achieved without irrigation. By autumn, most of us are resigned to a somewhat scruffier appearance altogether. We lift our eyes instead in the hope of autumn colours from deciduous trees and shrubs.

Why do I say perennials are complex? There are so many variables. Not only is there below ground – the root systems and how these grow in conjunction or in competition with other plants – but there is such a lot to be factored in about above ground performance. Deciduous or evergreen, colour and shape of both foliage and flowers, peak display time, whether they need staking or dead heading and how often the plant needs lifting and dividing, size, how the plant looks when outside its star performance time, requirements for water, frost protection or winter chill let alone sun and light – and that is not a comprehensive list. These vary for each plant type. It is a lot of knowledge to build up.

The skills lie in avoiding the mishmash or hodgepodge effect. No wonder people go for the easiest option and mass plant a single tried and true ground cover perennial. The aforementioned Xanthe White article gives you a mid-line option if you want something more interesting but still relatively easily managed by the home gardener. I am anticipating spending the next decade at least getting to better grips with perennials before I think I will be happy with the results I can achieve. But that is fine. We have never seen gardening as a path to instant gratification.

Plant Collector: Chaenomeles

022Not quinces, as most people think, but chaenomeles or japonica apples. At this time of the year, the hanging golden orbs are a most attractive feature. I like to bring a bowl indoors because they are scented, in an aromatic apple-y sort of way and they last for many weeks. The plant itself is a deciduous, scrubby shrub, maybe 2 metres tall and, after many years, 4 metres wide. It has burglar deterrent possibilities with its ferocious spines but is not a thing of natural beauty beyond its attractive fruit in autumn and its lovely single, deep pink japonica flowers in spring. It will have been a named form that was purchased but the name is lost in the mists of time. It appears to be a hybrid – a cross between 2 of the 3 different species, selected for both flower colour and fruit and is most likely to be in the Chaenomeles x superba group. We have other forms that flower well but don’t fruit in the same manner.

Chaenomeles are native to Japan, eastern China and Korea. Unsurprisingly, given their long thorns, they are related to roses and in the roseaceae family.

The fruit is far too astringent to eat raw. I have been given a jar of japonica jelly but it was not memorable. Apparently they are very high in pectin so I may try boiling some down to use as a base for orange marmalade. I tried making chaenomeles brandy one year and it was fine, but we are not so keen on liqueurs in this household. I would rather drink the brandy without the year steeping with sliced chaenomeles and sugar.

Plant Collector: Dietes grandiflora

062There is nothing unusual about the dietes flowering at the moment, but don’t let the fact that it is much favoured by amenity landscapers put you off. The reason it is seen so often in shopping centre garden plots is because it is tough and easy care.

It is a South African wild iris. Originally it was thought to be a moraea – commonly known as peacock irises – but that family grows from corms whereas the dietes forms rhizomes. Its flowers link it to moraeas, its rooting structure to the iris. Apparently the word dietes means ‘having two relatives’. ‘Grandiflora’ just means large flower.

The foliage is narrow, upright and pointed and it is evergreen. For most of the year, it just looks anonymous and not very exciting but it has such pretty flowers at this time. These are short lived but, as with many other irises, there is a succession opening down the stem. If the blooms remind you of an exotic butterfly, you may be pleased to hear that it is sometimes referred to as a butterfly iris. It flowers best with sun. While the plant will grow in relatively shady positions, you won’t get anywhere near as many blooms so try for full sun or somewhat dappled light.

As a garden plant, unless you want your place to look like a supermarket carpark, veer away from mass planting in favour of interesting combinations. I think it looks wonderfully effective planted with the tractor seat ligularia (Ligularia reniformis) but any contrasting big, luscious foliage is going to work.
