April bulbs in bloom

2 Replies
Plenty of cyclamen flowering in shades of pink and pure white

Unlike earlier months, the April bulbs here have been a narrow range of different varieties, although certainly not in terms of numbers. The rockery in particular is a carpet of Cyclamen hederifolium but, as that became full, we have gently encouraged its spread to anywhere it wants to grow. It is very much the easiest and most adaptable of the cyclamen we grow.

Nerines and Moraea polystachya together

I wrote about both the Nerine sarniensis and the Moraea poystachya last month as they hit their peak. Both are heading towards the end of their season now but a six week season is a long time for a bulb.

The autumn snowdrops are always a surprise but at last I looked them up and I am pretty sure that these are Galanthus reginae-olgae, Queen Olga’s snowdrop. In the likelihood that few readers, if any, even know who this Olga was, I can advise that she was Olga Constantinovna of Russia who was also Queen of Greece at the time when a Greek botanist identified this species native to the area.

Now to commit the name Galanthus reginae-olgae to memory….

Mark often cites this snowdrop as an example of how even the most charming of bulbs is most charming when it flowers in the season when we expect it. Snowdrops, he feels, belong in late winter to earliest spring – harbingers of season change – and most of them do flower then and we are delighted to see them. It is why, as a plant breeder, he wants plants to flower at their allotted time of the year, not to appear as a novelty at the ‘wrong’ time.

I digress, but when a new species of camellia, known first as C. changii but then renamed to the less helpful but correct in plant nomenclature C. azalea, became available, his interest in acquiring it for breeding was decidedly lacklustre. Its main flowering is in summer whereas pretty much every other camellia flowers in autumn (for sasanquas and some species), winter or early spring. A summer flowering camellia still strikes him as fundamentally on the fringes of the natural order; after all, he argues, we have an abundance of other summer flowering plants and we don’t need a range of camellias flowering at the same time.

Schizostylis oo hesperantha. Or river lily, apparently.

A somewhat unsung but easy autumn rhizome is what we know of as a schizostylis but I see it is more correctly named as Hesperantha coccinea. I am not sure which name is easier to remember but maybe its common name of ‘river lily’ could be helpful, even though it is an iris, native to southern Africa and Zimbabwe. I see photographs on line of it growing in big clumps, but its foliage is unremarkable. I divide it up and dot it through the cottage gardens we refer to as the Iolanthe garden to add an extra bit of autumn colour and interest. It seems to be more favoured in the UK where it has a history in the cut flower industry and various named cultivars selected and even awarded by the RHS. Perhaps we are not so much into autumn bulbs in these southerly climes.

I made the mistake of planting O. eckloniana in a rockery pocket and have been weeding it out ever since. It is mighty handsome in a pot, though.

The other main group of bulbs just hitting their stride are the ornamental oxalis. Set aside your prejudices about oxalis – there are a few that are real pests and downright weeds but there are also some that are extremely ornamental – pretty as. But they are not all equal. Some have good looks but a fleeting season in bloom (here’s looking at you O. fabaefolia and flavas pink and white). Some are downright dangerous with thousands of teeny tiny bulbs that if you liberate in your garden, you will never get rid of unless you replace the soil entirely. Some are not strong enough to survive well in garden conditions and need to be nursed along in pots. But some are excellent in the garden and not a problem at all.

Oxalis purpurea alba. We find the pink flowered forms of this species invasive but this lovely white form is reasonably strong growing but not weedy and it is easy to remove entirely if required.
I would give the same verdict on O. luteola – long flowering season and garden friendly.

When our Zach was doing his apprenticeship here, he was required to curate a collection of plants and he chose oxalis. He has a collection of over 30 ornamental species now, most retrieved from the garden where I had planted them (and regretted some). They are variable in terms of garden merit but it is hard to beat O. purpurea alba and O. luteola as garden plants. Call them by their common name of wood sorrel if it makes you feel better.

Just a small sampling of the more than 30 varieties we have in the oxalis collection. There is a wide range of leaf type, flower size and colour.

And so to May this coming Friday. The new month will open with Nerine bowdenii, the last of the nerines to flower for us each season and the easiest to grow and bloom. I see its first flower has opened.

March bulbs in autumn

3 Replies

Autumn can be a magical season here. It is not guaranteed but, more often than not, we get warm, sunny, calm days with cool night temperatures. And dry. Ours is not a climate noted for extended dry periods but when it does happen, it is in autumn. These are perfect conditions for the autumn bulbs.

We say of our reasonably expansive 1950s rockery that it peaks in two seasons – autumn and again in early spring. We are entering the autumn peak but it is perhaps more in quantity than range of different bulbs.

We don’t accept many groups these days, but the Pukeiti members’ visit came from a special request, even though their visit was a few weeks too early to catch what we would describe as the autumn season.

We had the Pukeiti members visit three weeks’ ago and, as I commented to them, when it comes to bulbs, what they are looking at here is over 70 years of building up the volume. Mark, like his father Felix before him, started with just the bare minimum – one if it was an expensive bulb, maybe 3 or 4 if it was cheap enough and available to buy. Otherwise it would just be gifts of interesting bulbs from other gardeners. Over the years, we have lost a fair number of bulb varieties that did not like our conditions, but those that survived and increased have often thrived.

Cyclamen hederifolium, happily naturalised and seeding around but in a non-threatening way

The rockery is a carpet of Cyclamen hederifolium, in shades of pink and white. Sometimes referred to as the ivy-leaf cyclamen, it is native to the Mediterranean area and one of the most amenable and easy to grow species. These days, we mostly let them seed down in situ and from time to time, I will lift clumps of tubers when they get too congested.  We have also had success naturalising them on bulb hillsides in meadow conditions but we need to get the summer cut on the grass done at the right time so we can see the flowers. Somewhat to Mark’s surprise, just scattering seed proved as effective as planting tubers but it does take a few years for them to get enough size to be visible.

The nerines have just their peak. We do a good line on nerines – well, a rockery filled with them really and we have managed to keep the colours separate. Most are hybrids based on Nerine sarniensis, Felix started with a few good ones, although we don’t know how he came by the Inchmery nerines from Exbury. From there, he and then Mark started trying out controlled crosses to build the range we have today. They are the absolute stars in the autumn rockery, underpinned by the carpet of cyclamen.

Belladonnas are somewhat under-rated as an autumn bulb – too vigorous in growth habit and too much foliage for the rest of the year, but they certainly put on a great show in bloom with absolutely no care or attention.

Most of the big bulbs of summer have finished, but I will eat my past words on the short flowering season of belladonnas. I have never tracked them before but seven weeks in full bloom and still going is not a short season at all, by bulb standards. We just take them for granted, really, and fail to recognise what a hard working family they are.

Moraea poystachya in blue, choosing where it prefers to live. It particularly likes cracks in concrete.

The moraea family is a large one of many different species, the most common being M. villosa and M. aristata – the spring flowering peacock iris. Some are invasive and some are not worth having, but in autumn each year, Moraea polystachya delights us with its blue iris flowers. It sets plenty of flowers down the stem, unlike many bulbs that set just one bloom per stem. It seeds down but not badly enough for us to decide it is invasive and dangerous. It is just gently spreading and generally delights us,

Having different species of colchicum means the flowering season is extended by several weeks.

Beyond that, the second species of colchicums are in full bloom now (either C. autumnale or C speciosum – one flowers earlier and one flowers now and one day, I will find out which blooms first). So too are the true autumn crocus in bloom. There are a fair swag of different species of autumn crocus (NOT including colchicums and sternbergia which are often inaccurately referred to as autumn crocus even though they have no connection to crocus at all). The one we have most success with is blue, almost certainly from the C. serotinus group, maybe salzmanii.

The controversial pure while Lilium formasanum close out the lily season in March. They are controversial because of their seeding ways and indeed are banned from commercial sale but not prohibited in the garden. They do need deadheading, though.

Other bulbs during March that came and went included Haemanthus coccineus, Brunsvigia josephinae and the controversial Lilium formasanum (syn. weedy, also banned from sale). 

Sometimes this run of settled autumn weather can last until the shortest day. After a particularly indifferent summer, we have our fingers crossed.

‘Autumn is icumen in’

It is not ‘sumer’ that is icumen in here, but very much autumn that has announced its arrival.

It seems a lifetime since I studied English literature at university. I guess it is almost a lifetime ago and I have long since lost my ability to read texts such as Chaucer’s tales and ‘Sir Gawain and the Green Knight’ in their original Middle English. But how have I reached this age without ever knowing about the farting billy goat in ‘Sumer is icumen in’? (see below) I only found it this morning when I looked up the lyrics. It is perhaps a sign of times that were more bawdy than vulgar.

‘Icumen in’ does not translate to ‘is coming in’. It means it is here and nothing makes that seem more real than the end of daylight saving. I used to find the onset of autumn somewhat depressing, describing myself as a summer bunny. But now that I garden, it heralds the start of a new season with all the freshness of new season flowers.

Nerine sarniensis season! This is one of Mark’s hybrids – the long stems mean it would probably be better grown as a cut flower than a garden plant. The weight of the head can drag the stems down but we don’t do cut flowers so we just persevere with it in the garden.

In our climate, it also heralds the time when we can get back to planting, digging and dividing and renovating parts of the garden that are crying out for more drastic action. We still have up to two months of the growing season left here; the ground doesn’t get cold enough to stop plant growth until June. Indeed, for those people who live in areas with hotter, dry summers, autumn planting is often a much better option than spring planting because the plants can settle in and get their roots out before the stress of summer conditions sets in. Spring planting is the better option for those who live with harsher climates where the ground can freeze or is waterlogged and very cold in winter but most of our country can happily plant away in autumn,  safe in the knowledge that that the plants will over-winter and leap into new growth in springtime.

Autumn is the second season for the rockery. While there is always something of interest flowering 52 weeks of the year, autumn and early spring are when it bursts with colour and variety. Nerines feature large, particularly the sarniensis hybrids.

Most of our nerines are hybrids from both Felix and Mark’s efforts. We once named and sold a few but nowadays they mostly just exist in our garden. Every year, my camera fails to capture the truly startling shade of highlighter pink in this clump.

Felix started with a few named ones from Exbury. This is ‘Inchmery Elizabeth’ and has proven to be such a pretty and reliable performer down the decades.

I found this one snapped off, which may have been due to slug chomping on the stem or it may have been Ralph the dog who is no respecter of gardens but ploughs in when pursuing a fly, bee or wasp. What I think is interesting is the shade of purple it is fading to; presumably there are enough blue genes in there to indicate it is only a matter of time and determination by somebody to get to true purple and blue hybrids in the future.

Camellia sasanqua ‘Elfin Rose’

Autumn is sasanqua camellia season. This is sweet little ‘Elfin Rose’, which we cloud prune. Sasanquas don’t have to be white, as per the long-running fashion in this country.

Camellia sasanqua ‘Sparkling Burgundy’

The flower on ‘Sparkling Burgundy’ is not so very different to ‘Elfin Rose’ but the habit of growth is. This plant is decades old, maybe 50 years or so. We lifted it and thinned the canopy to turn it into a graceful, open small tree rather than a bushy shrub.

Camellia sasanqua ‘Crimson King’

Sasanqua camellias have softer flower forms and laxer growth than the more common japonica and hybrid camellias that flower in winter and spring but they don’t get petal camellia and we have grown to appreciate their relaxed informality of flower form. Alas that is a wasp feeding on the flower above but they are equally a source of food for the more desirable bees. Exposed stamens and pollen are the key to feeding bees.

Summer[a] has arrived,
Loudly sing, cuckoo!
The seed is growing
And the meadow is blooming,
And the wood is coming into leaf now,
Sing, cuckoo!

The ewe is bleating after her lamb,
The cow is lowing after her calf;
The bullock is prancing,
The billy-goat farting, [or “The stag cavorting”]
Sing merrily, cuckoo!

Cuckoo, cuckoo,
You sing well, cuckoo,
Never stop now.

Sing, cuckoo, now; sing, cuckoo;
Sing, cuckoo; sing, cuckoo, now!
What is there not to love about Cyclamen hederafolium. First the pretty, dainty blooms and then the lovely marbled foliage to carry through winter.

Waiting for rain

The Court Garden has barely turned a hair – or lost a leaf – in our unusually dry summer

It is unusually dry here. In fact our province of Taranaki went into official drought declaration some weeks ago. I was woken yesterday morning by the sound of rain and my instant response was relief but it stopped and I see it was only about half a millimetre so that did absolutely nothing.

Continuing dry weather has affected the floral display in the borders

People who live in habitually dry areas may scoff at what we declare as drought but it is all relative. For many years, I have been cheerfully declaring that we get around 150 cm of rain a year (1500mm or about sixty inches) fairly evenly distributed across the year. We might complain about the dryness if we get several weeks without rain in summer but we are generally confident that the rains will arrive in time. Our prevailing westerly weather patterns tend to mean that we get moisture-laden air coming in from the ocean. High sunshine hours and relatively high rainfall is the norm. Currently, we are about 60% down on our normal rainfall in the first months of this year.

Fortunately, we source our water from our own, private bore so we are not in danger of running out. The water delivery businesses must be booming with urgent calls from those rural folk who rely on rain water tanks or surface water sources. Stream and river levels are uniformly low.

The autumn bulbs are not bothered. They received just enough summer rain earlier to trigger them into growth. This is dainty little Leucojum autumnale. Its teeny tiny flowers are not much larger than a finger nail but it increases well.

When it comes to gardening, because we live in a climate with consistent rainfall, we have no irrigation system and we can only reach a few, small areas with a hose. Extended dry periods are a good test for us. When the hydrangeas planted in shade start to wilt, we know we are very dry.

We are not unduly worried yet. The rains should come.  It is frustrating though, for people who garden every day. It feels as though much is on hold, waiting for rain. We can’t plant anything much or dig and divide. But at least Zach and I got onto a messy border immediately behind the house. There is a water tap close by so we could do more.

A generally unremarkable border

One might describe it as an historic but unremarkable border, most of the permanent trees and shrubs having been planted by Mark’s father, probably back in the 1950s and 1960s. Over the years, it has received little intensive care or love, confined to weeding, removing dead plants, a bit of pruning and filling bare spaces but little else. The swathe of auratum lilies were crying out for some love.

The border goes from sun to full shade. This is Zach’s orchid construction at the shady end.

I haven’t counted the plant varieties but there must be at least 50 or 60 different ones in a curved area measuring up to three metres across and twenty five metres long. We pruned almost all the trees, shrubs, cycads and the like – a tidy-up really. The work came on the under plantings – the lower growing perennials and bulbs.

My mantra is that when there is a diverse top tier planting of trees and shrubs (like, one of each specimen), bottom tier plantings need to be simpler to give some cohesion. Our idea of simple may not be the same as many gardeners, let alone designers, but what Zach and I did was to consolidate the different ground level plantings into bigger blocks, rather than drifts or random placement. We removed some entirely (yellow tigridias and every last bit of green mondo grass), reduced some (it is very nice of Geranium madarense to seed down and naturalise but we only need four full-sized ones to make a statement next spring and a few younger ones for the year following – not 40), divided hostas and farfugiums and consolidated other plants into blocks.

Farfugium japonicum ‘Crispatum’ features strongly. I am going with the RHS name of this plant but a net search sees it listed under assorted variants including ligularia (first word), tussilagineum (second word) and Cristata or Crispata (third word) in every possible combination of those three words plus the three words of its RHS-accepted name.
Farfugium japonicum ‘Argenteum’ is showier but also much slower to increase. Fortunately, we used to sell it commercially so we had a jump start on having sufficient plants for impact in shady areas.

All plants that were lifted were plunged into buckets of water, replanted into holes enriched with compost, thoroughly watered and mulched. If we don’t get enough rain in the next week or two, we can easily reach them with the hose.

Just a reminder not to lay mulch when the ground is bone dry. It will act as a barrier to moisture entering the soil. Mulch needs to be laid to protect existing moisture levels in the ground before it dries out.

May the autumn rains arrive soon.

The rockery is so dry it is pretty much dust. There is no sign of life in the soils but the autumn bulbs are barely turning a hair at the conditions.

Harbingers of autumn

It may still feel like high summer where we are, but the flowers do not lie. We are on the cusp of autumn.

Colchicum autumnale

Summer here in North Taranaki has not followed its usual pattern. While we are always slower to warm up in November and December than the east coast, it didn’t really feel like summer until mid January. I don’t swim in cold water and I wasn’t tempted into the pool until well into January. Since then, we have been in and out of the water every day in an unseasonably warm and dry spell. A couple of degrees of extra heat on an ongoing basis makes quite a difference when you spend most of your days outdoors in the garden.

A stray belladonna in the raspberry cage was the first autumn bulb I noticed this season

And dry. I know when we talk about dryness, others may scoff. We all adapt to our own, local conditions and we expect rain on a regular basis all through the year. Mark, a keen weather watcher who could have happily pursued a career on meteorology, tells me we only had 40ml in January and that fell basically on one day, late in the month. We don’t ever water the garden (except for some of the vegetables) and we have no irrigation system; it isn’t necessary in our climate and nor does it seem like good practice but we are seeing some floppy looking plants and some early dropping of leaves.

Even the first nerines are opening

When the autumn bulbs started flowering in what still feels like high summer, I assumed they were being triggered by day length, as vireya rhododendrons are. They are certainly not being triggered by change in temperature, either day or night. Mark pointed out that it may well be that one day of rain in January that triggered them into growth and that makes sense because many bulbs are identified as summer rainfall bulbs.

Lilium formasanaum is a bit controversial in this country. It is on the Pest Plants Accord so illegal to propagate or sell. We keep it because it is showy and not a problem in our garden but also, it is not in a situation where it can escape from the garden to become a problem elsewhere.

Zach and I are waiting for rain so we can move plants again. We have plans we want to get underway. At least we know that here, with a temperate, maritime climate, the rains will come. While our high summer may be of short duration, so too is the depth of winter which we measure in weeks, not months. We have exceptionally long autumn and spring seasons and that does make for a good gardening climate.

A self-seeded Moraea polystachya on the side of the drive. Of all the autumn bulbs, this moraea probably has the longest flowering season.

The autumn bulbs are one of our seasonal highlights.

The Worsleya procera is opening! This bulb is one we take some pride in because it is rare in cultivation, even rarer to see it flowering in a garden situation and it is very choice. It is generally grown as a pot plant in carefully controlled conditions. The lilac colour deepens and spreads as the flower opens.
