Flowers from an early autumn Easter weekend

???????????????????????????????It is indubitably autumnal, but no sign of the leaves colouring or dropping yet as we gently drift into the cooler seasons. I shall do a survey of the plants that take us through autumn, I thought, and headed out to the garden with snips and a basket.

We love flowers – lots of flowers. Simple blooms, common varieties, oddities and curiosities, anything and most things (though not everything) across the colour spectrum. Some gardeners, presumably of more refined sensibilities, prefer to be restrained and to preach the value of form and foliage. We are happy to value form and foliage but we want the added appeal of flowery fluff softening the austerity.

???????????????????????????????Despite that slight sense of mournful decay that can characterise the autumnal garden, there was so much flying the flag for flowers that I had to group them. It is still early for the autumn bulbs. There is a whole lot more to come but the nine in bloom at least indicate that not all bulbs belong to spring. Starting with the white flower at the top of the photo, going clockwise, these are: Crinum moorei, belladonna, Colchicum autumnale, one of the autumn crocus (could be C. serotinus), Moraea polystachya which is an unsung star amongst the autumn bulbs, Cyclamen hederafolium both pink and white, the dainty little Leucojum autumnale, the earliest of the oxalis (hirta, luteola, massoniana and lobata) and the first of the nerines that will become the rockery stars over the next few weeks.
???????????????????????????????Climbers can be a little bothersome to place. Too many are strangling, invasive things, smothering their host as they scramble to the top, or, like the Rhodochiton atrosanguineus, seeding down in perpetuity. Others are such retiring little dainties that they can be difficult to keep going. Flowering for us at the moment are the bougainvillea (very much in the rampant camp) and one of the more garden-friendly jasmines at the top but we have lost track of which one it is. It has good fragrance, flowers pretty much all the time and is strong growing – bordering on rampant – but not as aggressive as the weedy jasmines. It is planted on the corner of the bedroom once inhabited by our daughter of the same name. Immediately below, the purple flower like a mini streptocarpus is on a soft vine, but its name escapes us at the moment. Well, I have never known it and Mark thinks he raised it from commercial seed but has yet to recall what it is. To the right are the lapagerias – Chilean bell flowers – with their wonderfully long blooming season and obliging habits. Sure it can take several – many, even – years to get a vine established but once there, these are rewarding plants for the shaded side of the house.
???????????????????????????????The flowering shrubs and trees are not so numerous at this time of the year. Top row left, we have Radermachera sinica (more on this below), Hydrangea Immaculata which is still at peak rather than that fading over to dusky spent flowerheads, next row down is the fragrant osmanthus (though not sure which one) and the so-called African butter knife plant or Cunonia capensis. Then comes the white flowered tibouchina which seeds down far too freely here but does compensate by flowering pretty much all the time in semi woodland conditions. Fuchsias are not a strong point for us, but the one on the left has been here forever it seems, surviving even falling over, splitting apart and drought. The one on the right is the attractive but dangerously weedy Fuchsia boliviana. Second row from the bottom is a sampling of vireya rhododendrons – have enough of these around the place and there are always some in flower, 52 weeks of the year. In the bottom row are the first of the evergreen azaleas embarking on their marathon blooming from early autumn right through to mid spring and the first camellia.
???????????????????????????????Camellia sinensis will no doubt be of interest to some. It is always the first to flower though with such insignificant blooms that they are easy to miss. This is the tea camellia, and yes, sometimes we do harvest the young leaves to make green tea. White flowered tea camellias are more common and we have a plant somewhere – in the “plant out” area, I think, waiting to get out of its pot.
???????????????????????????????I was pretty thrilled by the Radermachera sinica when Mark alerted me to it in bloom. It has a divine and heady fragrance. The trouble is that it is sub tropical to tropical so treated as a house plant in the temperate world. But it is a tree and ours is shooting skywards. Besides, we don’t do houseplants so we are yet to decide what to do with this plant besides enjoying its current flowering.
???????????????????????????????Finally there are the perennials and annuals still in full bloom. In brief in the yellow tones, we start with a damn big yellow salvia at the base and head around clockwise: kniphofia species, one of the gesneriad family whose name we have currently forgotten but which makes an excellent woodland plant, datura, dahlias, simple little autumn zinnias (none of the over-bred, bushy, compact, modern hybrid bedding plants), a handy yellow ground cover which flowers for a very long time and whose name will come back to us at some point, Hibiscus trionum and the common wildflower oenothera which is remarkably rewarding when it comes to blooming on and on.
???????????????????????????????In the pinks and whites, we start at the top with the under-sung white plumes of Actaea racemosa (syn Cimcifuga racemosa) whose fairy candles light up a woodland area, a simple dahlia seedling, the annual Amaranthus caudatus which is self sown, the lovely wind anemones, assorted daisies, streptocarpus (bit of one-upmanship here – we use these as permanent bedding plants in frost-free locations), one of the saponarias, a really old, self-maintaining strain of impatiens that has naturalised in our woodland, a self-seeded abutilon which should have been amongst the shrubs and some rather large and resilient begonias.

While others may find that buxus balls and refined plantings soothe their souls and give order to their lives, we like vibrancy to gladden our hearts. Besides, with flowers we get butterflies, bees and birds to enrich the scene further and we take delight in gardening to sustain a lively eco-system. That said, I gathered these flowers across a few acres, not from a few square metres in a back garden. I might feel differently with a more limited area. In the current situation, I can satisfy any need for more restrained style indoors.

Schooling the foxgloves

White foxgloves, though at Tikorangi, not Hidcote

An enduring memory of our visit to Hidcote Manor Garden in Gloucestershire was a simple planting of white foxgloves. They stood like grand white sentinels, belying their humble botanical status. A packet of white foxglove seed was top of the list on our next seed order.

Common foxgloves – and the white is just a form of the common Digitalis purpurea – are not difficult to grow. Not at all. We let some pink ones seed down through the park and in outlying garden areas. I think our widespread, dismissive attitude to foxgloves has to do with an earlier rural orientation in this country where such plants are seen as noxious weeds. But we are not farmers, so some seeding wildflowers naturalised on our property are not a problem, adding to biodiversity and providing a food source for insects.

???????????????????????????????The whites I wanted for my rose and perennial garden. After a few years, I am now moving them. They are too big and choke and swamp the smaller perennials I have in that area. I have found a couple of spots which they can have all to themselves. I was amused to see English gardener, Keith Wiley – for whom we have huge respect – on TV talking about growing plants in colonies but noting that some plants are so dominant that they do not want to grow in colonies. He cited foxgloves as an example. They are way too thuggish to co-exist happily with many other plants.

I could have saved myself a lot of trial and error if I had looked to the ground where the Hidcote foxgloves grew and taken note of what else did or did not grow there and how much space each huge rosette of leaves occupied. Instead, I was so enchanted by the summer display at eye level that I failed to observe further.

???????????????????????????????Carol Klein on BBC’s Gardeners’ World, once said that she sorted her foxgloves as juvenile plants – the pink ones had pink veining in the leaves and the crown whereas the white ones were all green. I am not convinced she is right though I went through a stage of culling all pink-veined seedlings. I am happy to stand corrected if somebody has been more systematic in assessing this, but I am pretty sure that I have pink-veined ones flowering white and vice versa.

What I can tell you from experience is that foxgloves have very large tops but small root systems so are easy to transplant even when quite large, as long as I reduce the foliage by anything up to 75%. They are tough. I am hoping by next year to have my white Hidcote sentinels flowering in abundance in positions where they can be glorious without smothering other plants.

Keeping our monarchs at home

Joe Pye weed is a handy source of nectar for the monarch butterflies. We have always known Joe Pye as a eupatorium but it has now been renamed Eutrochium purpureum

March is the month when we become aware that the days are shortening and night temperatures cooling but autumn? Not yet, at least not in North Taranaki where we drift ever so slowly from season to season. But every year, the same pressure comes on – the plight of the monarch butterflies.March is the start of the critical period. We have monarchs on the wing twelve months of the year in our garden. To a large extent, that is because we take active steps to guard the late season caterpillars. These are the ones that will chrysalis and hatch out as conditions for them grow more difficult. Given the short life span of a monarch butterfly – usually only a month, the internet tells me – it is these late season candidates which will winter over and guarantee continuance through next summer.

In North America monarchs migrate vast distances to over-winter in the mountains of Mexico but our monarchs are not as determined and will stay at home. Occasionally we find a tree where many are clustered together and it is truly a small wonder in our world to see them stretching and flexing their wings in what little warmth there is on a sunny winter’s morning. More often, we will see raggedy specimens bravely feeding from seasonal plants. The so-called Edgeworthia papyrifera (yellow daphne) can be an astounding sight in August. The key to keeping our monarchs close to home is year-round food supplies, which means plenty of flowers with visible stamens and pollen which are a fair indicator of available nectar.

Swan plants are the food source for monarch caterpillars

Swan plants are the food source for monarch caterpillars

No doubt many readers are currently suffering the seasonal anxiety of stripped swan plants and a surfeit of caterpillars at all stages of development. The caterpillars are very selective about food sources. Basically they need swan plants. We always knew these as Asclepias fruticosa but I see they have now been reclassified as Gomphocarpus fruticosus for the common one and G. physocarpus for the giant swan plant and I can’t commit either of those names to my memory. You can – and we have in the past – get medium and large caterpillars to chrysalis-size on slices of pumpkin but you have to confine them because they will head off looking for their preferred food source given the opportunity. Is there anything as brave as the sight of a procession of monarch caterpillars heading away in search of more food?

Nowadays we try and reserve plants for late season caterpillars, covering them with netting and taking steps to rid them of the nasty yellow aphid that can decimate the plants. There is a specific aphid spray that does not harm the caterpillars when infestations are really bad. Both Yates and Tui have organic products that target mites, whitefly and aphids. Later in the season, Mark will start his chrysalis rescue programme, carefully tying them with cotton to suspend them safely because they can rarely hatch successfully if lying on the ground.

We are working to establish the admirals in the garden, seen here feeding from Lycoris aurea last autumn

We are finally getting patches of stinging nettle established. The only reason for this is to encourage the admirals, both red and yellow, to move into our garden. It is not our large native tree nettle – Urtica ferox – but one of the dwarf ones which has turned up which we are allowing to stay. Unlike the monarchs, which are self-introduced to this country and were first recorded around 1840, our brand of red admirals are truly indigenous and not found anywhere else in the world. Because their host plant is not as obliging and hospitable as the monarch’s swan plant, they need all the help we can give them. That said, there was a news item that came through at the start of this year reporting that the US Fish and Wildlife Service is taking steps to protect the monarch butterfly under the Endangered Species Act. Loss of habitat and modern farming methods have caused a massive drop in the monarch population and there are fears that, without intervention, they may die out.

Some utilitarians may ask what useful contribution butterflies make to human life. It is true that there their direct contribution does not equal that of bees. But as gardeners, most of us set out to cultivate transient and ephemeral blooms for no other reason than that they are beautiful and bring delight. Butterflies are beauties of the insect world and their continued presence is a good indicator of a healthy ecosystem.

New Zealand has an active Monarch Butterfly Trust with a comprehensive website. While the obliging monarch is their main focus, they cover the whole range of butterflies found in New Zealand (which is not large by international standards) and they touch on the moths (which are considerably more numerous here but less appealing to most people). You will find answers to many specific problems on that site. While the obliging monarch is their main focus, the site has information on a whole range of butterflies found in New Zealand, which is not large by international standards, and they touch on the moths, which are considerably more numerous here…but perhaps less appealing to most people.

Bamboo but where are the panda bears?

Phyllostachys edulis but, alas, no panda bears

Phyllostachys edulis but, alas, no panda bears

We have the odd stand of bamboo around the place. This giant form is Phyllostachys edulis.

???????????????????????????????

There are no fewer than 42 different species that giant pandas eat. Mark told me that P. edulis is one of them so I briefly entertained the cargo cult dream – grow the food and wait for them to arrive – but sadly that seems unlikely. A net search does not highlight P. edulis as one of the pandas’ preferred species so maybe that is the problem? We have
tried harvesting the young shoots to eat and they were fine, if n???????????????????????????????ot sufficiently inspiring to ensure that they became a dietary staple. It is, however, a useful source of very long and remarkably stable poles. One is a prop for the washing line. Mark uses it to build shelter frames for his bananas and even to make super long handles for the rake he uses to clean out our ponds. Inspired by our awe of bamboo scaffolding in Hong Kong, seen on high-rise buildings, he threatens to construct our own scaffolding but I think it is all talk.
??????????????????????????????? ???????????????????????????????
I photographed this bamboo screen in a Herne Bay garden during the recent Heroic Gardens Festival. It was a lovely small town garden which successfully utilised pretty much every bit of available space to integrate the indoors and outdoors as living space. I really liked the informality of the screen, with the varied lengths of bamboo rather than forcing them into uniformity and the natural weathering process. Mark was particularly taken by the close-up photo showing how the lengths were held in place. Cable ties – a wonderfully simple idea.
??????????????????????????????????????????????????????????????Also seen at Heroic was this crafted bamboo gate in a Mount Eden garden, which was beautifully executed and appropriate to the restrained, immaculately maintained sub-tropical back garden. This is located in the heart of a densely populated urban area but the garden gives no hint of that. The gate has clearly been coated, presumably both to prolong its life but also to stop the weathering process and preserve the smart, new appearance. Sealing the bamboo will also stop the growth of lichens.

 

???????????????????????????????
???????????????????????????????At the other end of the sophistication scale, I photographed these two bamboo gates in an Okato garden last spring. These have been added on to existing gate frames in a garden where many different bamboos are grown, and then left to weather over many years. You can see the high humidity environment and clean atmosphere in our coastal Taranaki that encourages such abundant lichen growth. As long as the bamboo is kept off the ground, it can last a surprisingly long time.

The best bamboo collection we know is at Paloma, Clive and Nicki Higgie’s garden at Fordell, near Whanganui. Bamboo enthusiasts will find much of interest there. But no panda bears, alas.

Heroic despatches 4: A Restful Green Heart

???????????????????????????????One of the delights I appreciated at the Heroic Gardens Festival was this quiet, simple green space in the back garden owned by photographer, Gil Hanly.

I have written before about the green breathing space As a sorbet between rich dinner courses refreshes the palate, so too do simpler areas in a complex or busy garden allow a little space to draw breath. Generally, I have seen lawns used to achieve this quieter space.
???????????????????????????????
Gil Hanly’s was a complex and mature garden with many points of interest. Her vegetable garden was a tour de force but in addition to that, there was a lot happening all through her garden. And out from the house was this charming green space of deceptive simplicity. A grove of palms underplanted with mondo grass fringed a dark natural-shaped pond in the shade, creating a restful, central heart to the garden. It was simply lovely. I can only apologise for failing to take more notice of which palms were used. I lack any expertise on this plant family and always defer to Mark who was not with me on this trip. With hindsight, we wonder if they are Hedyscepe canterburyana but that is only a guess.

The sauntering ducks are bamboo, collected by the garden owner on a trip to Asia (she may have said Vietnam).

147??????????????????????????????? The little temple by the water (top) is, I am told, by artist, Bronwyn Cornish. For me it evoked the very old villa visible in a ravine in Sorrento in Italy (immediately above) which I photographed back in 2008. Anyone who has been to Sorrento (the jumping off point for Capri) will have seen this sight. In the Hanly back garden, the whole effect was understated but hugely effective.

Unrelated, there was also a huge plant of our very own Cordyline Red Fountain growing elsewhere in the garden in an area which was bold with colour.
