The end of the long, hot summer is nigh

Belladonnas – a roadside flower for us

Summer continues here with temperatures in the mid to late mid twenties during the day, and often not dropping much below 17 at night. That is celsius, of course. With our near-constant high humidity, it feels hotter. Dry heat is easier to live in. But we are not complaining. Last summer never really arrived and we would have been lucky to have a single day where temperatures reached 25 or 26, rather than the three months so far this year.

Our belladonnas range from pure white through pretty pastel pink to sugar candy pinks and all shades between

What is interesting is that while the temperatures haven’t really dropped, the garden is starting to tell us that autumn is coming. The belladonnas are already past their peak, Cyclamen hederifolium is in full bloom  as is the tiny, dainty autumn snowflake, Leucojum autumnalis. Moraea polystachya has started its blooming marathon.Even the first nerine has opened and I spotted a flower on an autumn flowering camellia – C. microphylla. Haemanthus coccineus is out and the exquisite Rhodophiala bifida have already been and almost gone, their lovely trumpet blooms touched with gold dust now withering away for another year.

Cyclamen hederafolium seed down happily for us now

Some plants are triggered into growth or blooming by temperature, some by seasonal rain (we can do the South African autumn bulbs so well because we get summer rain, even in a drought year such as this has been) and some are triggered by day length. While our weather conditions are still indubitably summer, the day length is shortening and these plants are programmed to respond.

We don’t get sharp seasonal changes because our temperature has quite a small range from both summer to winter and day to night. It will be another three months before the trees start to colour. But the garden is coming out of its summer hiatus and entering autumn, whether we are ready or not.

Stachys Bella Grigio is giving up the ghost. Whiffing off, as we say.

Some plants just like to confound you. I wrote earlier about Stachys ‘Bella Grigio’, the startling white, felted variety that was so happily ensconced in a new garden. Booming away, even. It was setting so many offshoots that I thought I would be able to carpet many square metres by the end of the season. Well, it was an ‘upanddieonyou’ after all. It has been upping and dying like mad in the last weeks. Otherwise known as ‘whiffing off’ here.

I dug up a couple of wilting plants to see what was going on. They are dying from the top down. Their roots are fine. As an aside, if you are puzzled by why a plant is clearly dying, basically they die either bottom up or top down so it is always interesting to carry out an autopsy. Each of these plants was carrying 30 or more offshoots. I took off the ones with roots and have tried replanting them and I thinned out the offsets which had not yet established their own roots because it looked a bit as if the plants were smothering themselves to death in their desire to reproduce. There was no sign of insect infestation.

“It’s probably climatic,” Mark said. His thinking is that we are too humid and it has been particularly so this summer, whereas that felted white foliage is usually indicative of alpine plants. I think it is varietal. I have heard too many stories from others who have experienced specimens of this plant thriving, established and growing well before suddenly keeling over and dying. I cleaned up two plants and replanted the offsets out of curiosity. If I have to do this every year to keep these plants alive, then I am afraid I will decide very soon that it simply is not worth the effort.

We have mown the meadow for the season. Well, Lloyd has. With our special sickle bar mower, imported from Germany. We are still learning how to best manage the meadow in our conditions and Mark thinks that we are leaving the mowing too late and that it would be best done soon after Christmas for the first mow with a follow up in autumn. Maybe next year.

Mark has just declared that the sickle bar mower is otherwise known as the primary herbivore here. He has been reading about eco-systems and wondering what we could be introducing to NZ, given that our primary herbivore, the moa, is now extinct.

You can tell our climate is mild. We have begonias as a roadside hedge.

At the end of a golden summer come the autumn bulbs

Colchicums, not autumn crocus

Autumn. It is indubitably autumn. I can no longer pretend it is just the summer slowly waning and that winter is still a long way off. For most people, autumn is synonymous with leaves colouring to fiery hues.

However those of us in coastal areas may carry that mental image but the reality can fall well short. Inland areas get much better autumn colour because the nights cool down more rapidly and it is the sharp drop in temperatures which triggers the colouring response in most deciduous plants as much as the declining day length. The moderating effect of the sea means we drift far more slowly between seasons and the leaves are inclined to turn brown and fall, skipping much of the colouring process.

Our extensive use of evergreen plants in this country also mitigates against fantastic mass displays of autumn colour. Our native plants are all evergreen and in a generally benign gardening climate, we tend to favour evergreen exotics as well. I have met many gardeners who shun deciduous plants because they are allegedly messy and lack winter interest, which has always seemed a bit myopic to me. We are never going to rival countries like Canada with its native maples when it comes to a mass blaze of autumn tones.

It is the autumn bulbs that signal the change in season for me. There are so many pretty seasonal flowers coming through now. These are triggered into bloom by a drop in temperature, declining day length and some by late summer rain – don’t laugh at that last one.

The charm of carpets of Cyclamen hederfolium

Gardeners in this country tend to focus on the spring bulbs – from the early snowdrops through the snowflakes, bluebells, tulips, daffodils, anemones and ranunculus. These are readily available and marketed widely. They also flower at a time when the majority of trees and shrubs are blossoming forth.

The autumn bulbs have never captured the market in the same manner yet they bring freshness to the garden at a time when many plants are looking tired or passing over. I find them a wonderful antidote to the autumnal despondency of declining day length. There they are, all pretty and perky, just coming into their prime.

I often feature selected autumn bulbs in Plant Collector because this is their time to shine. As I wander around the garden, I see carpets of Cyclamen hederafolium (flowers only so far – the leaves have yet to appear) and taller spires of the autumn peacock iris, Moraea polystachya, which is inclined to seed itself around a little. This lovely lilac moraea has one of the longest flowering seasons of any bulb I know. The common old belladonnas are already passing over but I enjoy their blowsy display while it lasts. We use them in less tamed areas on the road verge.

Over the years, I have waged a campaign to convince people of the merits of the ornamental oxalis, many of which are autumn stars. Call them by their common overseas name of wood sorrel, if the mere mention of oxalis makes you shudder. The range of different species is huge. By no means are all of them nasty weeds and many are not the slightest bit invasive. We have them flowering in white, yellow, apricot bicolour, a whole range of pinks, lilac, lavender and even crimson. Some are perfectly garden-safe. I can vouch for their good behaviour after decades in the garden here. Others I keep in pots – preferably wide, shallow pots for best display.

We are big fans of the Nerine sarniensis hybrids

And nerines are the major feature of our autumn rockery. The majority of these are sarniensis hybrids with big heads of flowers. By no means are all of them the common red of Nerine fothergillii or the strong growing pink Nerine bowdenii which comes later in the season. We have some lovely smoky tones, reds deepening to violet hues, a remarkable lolly pink – the colour of a highlighter felt pen, two tone sugar candy and even heading to apricot. Nerines are renowned as a good cut flower but I never cut them. There is only one stem per bulb and I would rather admire them in the garden than indoors.

Then there are the bold colchicums which, contrary to popular belief, are not autumn crocus but certainly put on a splendid show with a succession of flowers from each corm. You have to go a long way back in the botanical family tree to get any relationship between colchicums and the proper autumn crocus. The latter is a much more delicate and transient performer whose flowers appear at the same time as its foliage. Currently, we are enjoying both in bloom.

Some bulbs are quite transient in flower but no less delightful for all that. If I am ever forced by declining health and aged frailty to trade down from a large garden, I can see that it would bulbs that I would chose to grow. I love the way they mark the seasons and how there can always be a different one coming into its time to star.
