Bits and bobs on a winter’s day

It has been a bitter cold week over the entire country, it seems. These matters are all relative; our daytime temperatures have barely made double digits so sitting in the 10°C to 12°C range with night temperatures about 10° lower. We have certainly complained at length about it. I have been most appreciative of the cheerful narcissi in flower. Yellow must be the most universally cheerful colour of all.

Narcissus cyclamineus hybrids raised from seed

We like the early flowering ones. They cheer up a winter’s day and they are done, dusted and starting to die back when the nasty narcissi flies start hatching out as spring warms up. If you think your narcissi are reducing in number or if they are all foliage and no flower, dig up a few and examine the bulbs. If they feel soft when you press them and if they have few or even no roots, then you have an infestation of narcissi fly.

Three archways of Podocarpus parlatorei

Zach has started the spring trimming round. First up were the Podocarpus parlatorei arches. It is a podocarp, as is our native totara, but this one is from Argentina. Mark had them as pillars but when Zach joined us in 2021, he started training them as arches. We own good, tall ladders in case you are wondering. Unfortunately it all has to be clipped by hand because the stems just bend with the electric hedgetrimmer but the end effect is to add some formality to the summer gardens, a defined axis.

Wavy hedges but in camellia plants, not the more common buxus. We had three visible frosts in a row on this week of cold temperatures.
Camellia microphylla is pretty enough in flower in autumn but it only has a short season

The arches terminate at what we refer to as the wave garden on account of the wavy hedges. Those undulating hedges are not an original idea; we have seen them used overseas and they are a hallmark of English designer, Tom Stuart Smith. However, they are usually done in buxus hedging. Our ones are in Camellia microphylla. This species camellia has a short but pretty enough flowering season in autumn so it has finished for the year. The advantage of using a camellia is that it doesn’t get buxus blight and can be left entirely to its own devices bar one trim after flowering and second tidy-up after its spring flush of fresh foliage.

Gloriosa in bloom during summer
Gloriosa tubers are more commonly the size of the two which are on the bottom

Look at these gloriosa tubers! The so-called climbing lily is not a lily but it is a good cut flower in summer. It is also making itself a great deal too comfortable so we are often thinning them. Zach dug out a bucket full and verily, we were astonished at their size. The smaller two at the front of this photo were what we would usually refer to as a good size, certainly not small. But they are utterly dwarfed by the big thumpers. Gloriosas are actually part of the colchicum family. The gloriosas grow from the tips, not from the centre V (which was last year’s growth point) so you need to make sure your tubers have at one intact tip, preferably two if you are buying it.

Helleborus foetidus deserves a more flattering name

Finally, I say I am not the world’s greatest fan of hellebores but really, I think I should limit that to the common Helleborus orientalis. I think they often perform better in colder climates whereas we can grow some lovelier plants in our generally temperate conditions (cymbidium orchids, amyone?). But look at this fine, self-sown specimen of Helleborus foetidus. And spare it a thought. I went to check the spelling and came across its Wikipedia entry:

Helleborus foetidus, known variously as stinking hellebore, dungwort, setterwort and bear’s foot, is a species of flowering plant in the buttercup family Ranunculaceae, native to the mountainous regions of Central and Southern Europe and Asia Minor.

What did it ever do to deserve descriptors of stinking and dungwort. Dungwort? I have never actually noticed its aroma but I have often thought ‘now there is an under-sung, remarkably elegant plant’.

Stay warm if you are in Aotearoa this week. Stay cool if you are in the northern hemisphere, suffering from extreme heat, drought and rampant fires.

Westward ho!

I am somewhat late in posting this first of a new series – month by month in the garden here, as printed in the June issue of NZ Gardener. This issue heralded some innovative changes in content for this magazine. If you haven’t looked at a copy recently, you may like to pick up a new issue.
???????????????????????????????There is nothing like the advent of the winter months to remind us that our climate is pretty good. Where we garden, on the coastal strip of Taranaki, we share the same disturbed westerly air pattern that moderates the climate of much of the west of New Zealand. It means we don’t get particularly cold and occasional frosts are generally light. We don’t put our gardens to bed for winter and retreat indoors. In fact we have colour and bloom all twelve months of the year and June is one of our busy months for planting trees, shrubs and perennials.

Not much shouts mild climate more than bromeliads and luculia flowering as winter sets in. True, we place our tender material with a bit of shelter from trees and these are only options for coastal gardens this far south, but bromeliads in bloom are a special touch of exotica when you have to start wearing extra clothing layers. Just don’t be like the cantankerous garden visitor who sniffed, “Oh I hate bromeliads, they looks so artificial.” “Well you won’t like this bit of the garden,” I replied and left her to it.

Luculia Fragrant Pearl

Luculia Fragrant Pearl

I love luculias, though not so much the form most readily available, Luculia gratissima ‘Early Dawn’. I find the candy pink a little harsh and it is not as fragrant as the L. pinceana forms. ‘Fragrant Cloud’ has huge heads and wonderful scent with subtler almond pink and white colouring. ‘Fragrant Pearl’ is a white pinceana selection we released but it appears to have dropped off the market now which is a pity because it is very good, with large blooms, strong perfume and a long flowering season. If you have a home propagation set-up, ideally with a bit of mist, luculias are not difficult to root from cutting. We used to try and get the cuttings in around Christmas but you can probably do it any time the fresh season’s growth has hardened sufficiently.

The trade-off for our milder winters is that we don’t get the sharp change in temperature that is an important trigger for glorious autumn colour. Plants that colour up well in colder, inland areas often just turn brown and drop their leaves here so we have to celebrate those that do give us small pictures of autumn glory. The Japanese maples are reliable and hang on to their blaze of colour well into winter. We will prune and shape our dwarf specimens (often sold as ‘patio maples’) once their leaves drop.

The autumn flowering sasanqua camellias are passing over but many of the species are in bloom and the early japonicas and hybrids are starting. Every year I fall in love with these early season blooms all over again. The love wanes somewhat when petal blight strikes, but the pristine purity of the first flowers is special.

June is one of the quieter months for bulbs. Nerine bowdenii is the last of that family to flower for us and takes us well into winter while Cyclamen coum forms carpets beneath larger shrubs. Mind you, it takes many years to get enough to form carpets and they won’t seed down if you garden with weed killer. July is the big month for the start of winter and early spring bulbs.

???????????????????????????????We are off to England to look at summer gardens this month. There is much to learn from their skills with summer flowering perennials and we particularly want to look more closely at what is now called the New Perennials Movement (which might be styled ‘meadow gardening and grasses meet traditional herbaceous drifts’). We have to squash any such trips in before the glory of the magnolia season starts here next month.
