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.

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.

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 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.
