Spring pinks

Pink froth of Prunus Awanui  currently at its peak

I am a big fan of pink and not just in flowers, but my theme this week came because of two pink plants in bloom.

The balls of viburnum are at the front of the vase

The first is one of the Virburnum × burkwoodii cultivars. I am not sure which one it is but we have it planted beside the drive where it is largely anonymous for 51 weeks of the year. In the 52nd week, it opens its flowers to rounded balls of exquisite fragrance – strong enough to hang in the air several metres away. We would be lucky to get a full 7 days out of it but I am sure it does better in other climates – it probably wants it drier and colder. I picked a few balls to put in a vase with pink bluebells and late flowers of Mark’s Daphne ‘Perfume Princess’ (which still has flowers and has had since late March). It was lovely but the viburnum flowers promptly died overnight. They last longer than that on the bush, though not by much.

The second pink to give me daily delight is Magnolia ‘Serene’ – bred by Felix and the marker of the end of the deciduous magnolia season for us. As we sit having our morning cup of tea, it is framed in the corner window of our bedroom. Not this morning, though. With daylight saving, it was a bit dark at 7am to see it so that may herald the end of that particular seasonal pleasure, too.

Rhododendron Coconut Ice

I am not the world’s biggest fan of the ball truss type of rhododendron but ‘Coconut Ice’ was looking particularly pretty earlier this week. Sadly, it is browning off already. Flowering is an ephemeral pleasure. Mark observes that the delight of rhododendrons lies in watching the buds for a long period of time before finally opening over a period of a couple of weeks. There is then a week, maybe 10 days, of full glory – sometimes cut shorter by an ill-timed storm – and then it is time to dead head it. In practice, we don’t dead head all our rhododendrons – just those that set large amounts of seed which can weaken the plant over time.

My rhododendron preference is for those with looser trusses that are sometimes so abundant that they can cover the plant.

Rhododendron Anne Teese

It took a couple of goes for Mark to remember the name of this beauty – Rhododendron Anne Teese. It is an Australian-bred hybrid coming from the Teese family (in this case the father, Arnold) who are well known through their nursery, Yamina Rare Plants in Monbulk, Victoria. Mark thinks it was named for the mother, presumably married to Arnold. Whatever, it is very lovely and I would be happy to have it named for me. It is a Maddenia hybrid (R.ciliicalyx x R.formosum) so scented and with a heavier petal, more weather resistant than ‘Charisma’, a similar R.ciliicalyx selection that used to be widely available here.

Rhododendron Floral Gift in a swathe of bluebells

With one notable exception – Magnolia ‘Felix Jury’ – Mark doesn’t name his cultivars for people. Or when he does, it is by oblique reference at best so an in-house tribute only. So this, his most fragrant rhododendron is ‘Floral Gift’, not ‘Abbie Jury’. It takes a while to get established but it is lovely and can be seen performing really well at Pukeiti Rhododendron Gardens. There are a whole lot of hybrids in this genre of scented, white flushed pink loose trusses; the best known is ‘Fragrantissimum’.  What sets ‘Floral Gift’ apart is the large flower and the very heavy petal texture giving it good weather resistance.

The reason I often reference weather resistance is because our spring flowering coincides with the spring equinox when we get the most unsettled weather, as evidenced this weekend – which, for us, means very heavy rain and wind which can wipe out fragile flowers in a matter of hours. And a few more pinks to finish off – this is one of the Dendrobium ‘Bardo Rose’ group of orchids which thrive in our open woodland areas. They flower for a long time and the scale is right for detailed woodland plantings – by which I mean, not as big and dominant as the cymbidiums.

Fairy Magnolia Blush

Fairy Magnolia Blush has a good, long flowering season, currently at its most charming stage of peak bloom. More lilac than pink, it is pleione orchid time. This is another group from the orchid family that thrives in pretty laissez-faire woodland conditions (in other words, benign neglect) but the flowering season is much shorter than the dendrobium ‘Bardo Roses’.

And the final bar of pink can be left to the evergreen azaleas. We have so many different ones that we get many months in flower but they are currently at their showiest.

Exotica in the shade

Shade gardens we have a-plenty

Shade gardens we have a-plenty

Glory be, but I do love spring.  This month subtropical bulbs and orchids shout out to be noticed.

We have extensive shade gardens. It is an inevitable result of a large, mature garden with many evergreen trees dating back as far as 1870. We do a lot of what we call lifting and limbing – taking off lower branches and keeping areas open to the light, for there are not a lot of plant options when it comes to deep, dark shade. Beneath the mighty tree canopy, it is dry but frost-free with dappled light. Over the decades there has been much trial and error to find what will thrive in these conditions and the plantings have become increasingly complex.

Dendrobium Bardo Rose

Dendrobium Bardo Rose

By this time in spring, we are over peak season for cymbidium orchids but the Australian dendrobiums are a delight. These are much smaller and more mounded or clumping in appearance and they take care of themselves. We have found the Bardo Rose group to be particularly obliging and free-flowering in woodland conditions. Ours all came from the local Orchid Society, an organisation that we have found combines generosity with superior technical knowledge.

Pleione orchids in the woodland

Pleione orchids do not last as long in bloom as many of the other orchids. Their flowers are soft rather than waxy but oh my, they make such a pretty carpet. It is easy for them to get swamped so we try and keep the area around them open but beyond lifting and dividing every few years, we just leave them alone. In our experience, the lovely yellow varieties do better in a climate where they get more winter chill. I think all our yellows have died out now but we have plenty in shades of lilac, purple and pure white. Most of our successful varieties came from the late George Fuller, orchid expert and former curator of Pukekura Park, and seem to have formosana in their parentage. If you want to build them up, a single bulb will usually set 2 offsets each season so you can double them every year.

Calanthe orchid - CopyThe calanthes are ground orchids and we have big clumps now because these obliging plants can just be left to quietly increase in size. These are fully evergreen and somewhat frost tender but they are a delightful sight through spring and they combine very well with clivias, ferns and even hostas.

Hippeastrums are a plant family that has been much hybridised but I am not entirely convinced that has been to their advantage. It is two species that we rely on, both South American. It was by chance we found they settled happily into woodland conditions. In full sun, they were ravaged by narcissi fly but in high shade they are fine. Apparently nazi flies, as they are often called, don’t like shade. H. aulicum is one of our early to mid spring mainstays, flowering consistently year in and year out while multiplying most satisfyingly. To me, they look like beautiful Jacobean lilies in the woodland.

Hippeastrum papilio has been a more recent acquisition for us and it is certainly spectacular, looking more like an orchid than the butterfly for which it was named. It is offered for sale but be prepared to pay a lot for a single bulb – maybe $30 if it is flowering size – because it takes several years to get to that point. I can’t think that we would have started with more than just one or two bulbs at that price. I see with a bit of dividing and replanting we now have about sixty but not all are flowering size yet. Mark has done some hybrids of aulicum x papilio to increase numbers and get some variety, but they have yet to bloom.

I will have to leave the arisaemas, trilliums and the Paris polyphylla for another time but will finish with Scadoxus puniceus from South Africa. Many readers will be familiar with the summer flowering red S. multiflorus ssp. katherinae, especially in the Auckland area because it was, and maybe still is, much beloved by landscapers. It is a mainstay of our summer woodland, but in spring it is the lesser known S. puniceus that is the showstopper. Growing from large bulbs which are slow to increase, the foliage is lush and the large blooms are curious rather than beautiful. S. puniceus is not widely available, but if you can find somebody with it, it is easy enough to raise from fresh seed as long as you are willing to wait quite a few years to reach flowering size.

The rewards are there for patient gardeners.

Orchids as garden plants

Referred to here as the Aussie dendrobes - dendrobiums

Referred to here as the Aussie dendrobes – dendrobiums

We are at the peak of orchid season in the garden. There can be few plants which carry the aura of luxury and exotica accorded to orchids. They belong to a huge and complex family, second only to the daisy family in number and go well beyond the common cymbidium. Yet they are not a plant that is common in New Zealand gardens.

The calanthe orchids are particularly rewarding as garden plants but you need to take the long view. We use them mainly as woodland plants. The blooms are a bit frost tender. Some we had on the margins were once hit by a memorable late frost but that was a one-off event. After about five decades of building them up, we have large swathes or drifts. In fact we have so many that a gardening ingénue who saw them recently drew the conclusion that they must be an unusual but easy bedding plant. Ah, no. But for those who have the time and inclination, they are a very rewarding branch of the family. Over time, they form a string of back bulbs below ground and can be increased from these.

For orchid enthusiasts who want the technical data, we understand that it is mostly forms of striata that are showiest for us. We have a pale lemon one which flowers in early spring and a much brighter yellow form that comes later. We used to have them under different species names but have come to the conclusion that they are more likely just different striata forms. Note: I have now been informed that the pale yellow calanthe shown is in fact Calanthe ‘Higo’ (C. sieboldii x C. aristulifera) which makes sense to us. We also use the white C. arisanensis but alas we failed with a lovely lilac species and appear to have lost it. All of these are evergreen varieties, though I understand there are deciduous species as well. The fresh spring leaves are large and could, at a pinch, be thought of as looking like pleated hosta leaves. A fair number of garden visitors over the years have asked us about the yellow flowered hostas. (Hint: hostas only flower in white or shades of lilac to purple.)

The Australian dendrobiums make compact, clumping plants with many smaller flowers and are pretty as a picture in the subtropical woodland areas. They combine very well with bromeliads and ferns and are an easy care garden plant. We have them in pinks, lilacs, white and yellow. We don’t know much about the hardiness of these. Ours are in positions where they never get frosted but they will get cold and they never turn a hair. They are probably similar to cymbidiums in hardiness.

Cymbidiums are the usual florist’s choice and are surprisingly easy as garden plants, given the right conditions. All of ours are grown in the ground, not containers. We don’t get florist quality blooms but they last an amazingly long time in flower and put on a splendid show as long as I remember to stake the flower spikes at the right time. I see I started photographing the flower spikes a full two months ago and those same flowers are now a little weather beaten but still showy. These days I harvest stems of green bamboo which still have convenient leaf axils because I can gently engage the flower spikes in the leaf axils and don’t have to tie each one which makes staking much faster and more discreet. I admit this only works if you have a convenient stand of bamboo to harvest.

The jury is still out on whether we can get the disa orchids naturalised by the stream. They were fine for the first two seasons but the proof of the pudding is in the five to ten year cycle – whether they are still strong and flowering after that time. At this point it is not looking good. The native English field orchid, Dactylorhiza maculata, has gently ticked on here for decades but is romping away more enthusiastically now we are trying cooler, damper positions. We didn’t succeed with the masdevallias (though we probably didn’t try very hard) and the tropical orchids like phalaenopsis (moth orchids) won’t do as garden plants for us.

One of the easiest orchids to grow - pleiones

One of the easiest orchids to grow – pleiones

This week it is the pleiones which are the stars. Their flowering season is nowhere near as extended as some of the other orchids, but they form pretty carpets, are not at all tender and are dead easy to increase. Most bulbs will make one or two offsets a year. Along with the dactylorhiza, they are deciduous, becoming dormant in autumn. The yellow pleiones want more of a winter chill and have gradually died out for us but we have an abundance of purest white ones and an array of lilacs and purples.

These are not generally plants that you will find offered for sale at garden centres (which may be why they are not often seen in gardens). You probably need to find your nearest Orchid Society and enquire about sales tables. Orchid enthusiasts tend to be a different breed. At the risk of making sweeping generalisations, Orchid Society people are more often collectors than gardeners. More than any other horticultural group we have come across, orchid people have well above average technical knowledge and like to show off their treasures in bloom. They are also generous and encouraging to any novice who shows an interest. Much of our collection has come from Orchid Society people over the years. We cannot speak highly enough of them as a repository of knowledge about a very complex plant genus.
