What's a tropical garden?

Let me introduce my beloved companion and exciting partner in life: Jacques-Emile Lecaron (link to his homepage on the right). When I started planting the garden, he was in Clamart, France (where it now snows...)

and we exchanged a few cerebral musings about gardens. This is his view of gardens: 

"The English garden is a pastoral approach. Its lawn is but an allegory of meadows; its temples and bridges are counterpoints embedded into a natural scene. Shepherd boys and shepherdesses are its divine tenders. It is anchored in the city—a patch of exotism for city dwellers who will sit and converse in one of its atmospheric edifices.  The English garden invites to reverse time and flow back to a pre-industrial Golden Age.

The garden à la française connotes nature differently. Domesticated wheatfields, croplands, bordering trees along roads, city plazas, channeled rivers are its basic material. The garden design extols urban space and life and veers its elements towards an enchanted future. Perspective lines shape the territory and suddenly reveal new vistas; the result is a public space, organized and ordely, yet supple. Sculptures associate with myths. Water features (allegories of dreams) trap the sky that they reflect. Groves balance the master plan; they are territories of love and poetry where human life bursts in between foliage, labyrinth, danse, theater, optical ambushes. The garden à la française is a dream machine, an opera. Designing such a garden is a challenge.

In Bali, beauty lies in the confrontion between sophisticated and architectured tropical flower beds and a lush and extremely diversified jungle. 
I agree with Made Wijaya, the author of "Tropical Garden design", that the tropical garden should convey a sense of outrage; it cannot be submitted to the subtleness of light, the seasonal changing of leaves color, or fragrances: it should be a substitute to the sky. Dark shadows, colorful light and exuberant foliage sweeps are expected. Flowers, fruits and foliage all add to the awakening of senses. The tropical garden is not an itinerary but a juxtaposition of selected vistas. Shadows will be overwhelming, while light is recreated in the rivalry of colors and the contemplation of water features—rivers, ponds, swimming pools.

The french and english gardens are exhilirating paths to the sky, to Paradise. One painting epitomizes this: Jean-Antoine Watteau's "Pèlerinage à l'île de Cythère" .

In the tropics, the sky is white, bright with heat and often stormy. It shelters neither paradise nor benevolent gods. Designing a garden that leads to the sky would be a misconception.

We can only try to create a paradise on earth, full of shapes and textures and colors, hoping and waiting for the gods to come and visit us. We will have to be dress up in our most beautiful attire and cook delicious meals. Perhaps the first muse to come will be "La charmeuse de serpents",  painted by the Douanier Rousseau.

An edible gardener goes carnivorous

It was not the plan, today, to launch this blog. I was planning for yesterday to recur: an early morning rise, a bike ride to Hôi An bus station (about 6 km from home) then a bus ride to Danang (30km) and a visit to plant nurseries. The bus ride should be an hour including stops, but there is a mysterious rote, exacerbated by yesterday's driver: the bus pulls out of the station, then immediately stops just a few meters later. A few people show up on motorbikes, not planning to board the bus: they haul on the empty rear part of the bus firmly packed goods to be delivered in Danang or on the way. A meeting is setup using the station name, and somebody will pick up the parcel. Instant, UPS style delivery.
Meanwhile, the passengers sit and wait. This loitering outside the bus station takes up at least twenty minutes before the bus slowly moves. By slow I mean 2 km/hour. It pulls to another stop three hundred meters later, at the cemetary. After some more dragging  for another twenty minutes, the driver finally consents to cull speed. When he does, he honks all the way to Danang, making sure the road is clear. Since the sound is deafening, he raises the sound system button to LOUD so everyone on the bus can enjoy the syrupy music.
In Danang, I am only familiar with its airport and the Cham Museum which houses the world's largest Cham sculpture collection—not surprisingly, since the Chams are an ethnic group originating from Central Vietnam. The 1915 ochre yellow building is a masterpiece of West-meets-East architecture, totally French and totally Cham. Naturally ventilated and uncannily cool, a 'green' building before 'green' became the hype. They just didn't have electricity-triggered air-conditioning back then.
It took a frustrating taxi ride to a wrong location and a moto-hug ride (that's how motorbike taxis are called—xe ôm) before I arrived at the short strip where plant nurseries are aligned. I am specifically looking for coconut coir hanging baskets to create a vertical garden wall.  I have never done this before, as I have never even gardened until two months ago. In this time lapse I have undergone several species addictions before currently arriving at the fern stage.
Why ferns? Well, ferns have been known to arouse pteridomania among the Victorians (check this link: http://www.peterboyd.com/pteridomania.htm) and the aesthetic reasons are many, but I am also attracted to the fact that they are undemanding in terms of light and soil: after two months of intense planting, the sunny spots in my plot of land have dramatically shrunk. Even the shady zones are beginning to be crowded. That is, horizontally. Also, an obnoxious air-conditioning compressor unit needs to be hidden (our house is 'green' and cool enough, but when it gets hot in Hôi An, it gets VERY hot).
The vertical option, made grandiosely popular by my friend Patrick Blanc, comes to my fertile mind that hours of researching on the Internet have thoroughly composted. 
Ferns! Their roots are capillarily thin and they can be grown with very little earth. The staghorn fern does not even require soil at all. It would be the perfect candidate for my wall, I thought. The centerpiece, which I would glamorize with tinier ferny items.
That was my reason to set off for Danang. In Hôi An, the horticulturists have yet to be itched by the pteridomania sting. When I inquire about the "Dragon's nest" (local name for staghorn fern—ổ rồng) they'd say, 'Oh, but dragons don't nest'.
The fern coolhouse, shielded from excess heat and sun, was easy to spot: stuff grow upside down. I walked in, hopeful, and bam, there they are, platycerium bifurcatum galore. I dashed towards the nursery owner: How much? Not identifying me as a serious buyer (ie, a buyer for the seaside resorts that abound the coastline), he reluctantly says: five million (250 USD). What? Five million dongs for a fern? No, for the whole crown.

I have this idea that my country fellows (whom I am about to offend irrevocably) are control freaks and nature haters. They are desperate to tame anything that grows—an impossible challenge in the tropics where ferns cascade and muscular sap stretches branches and leaves to unlimited extents. They recoil in presence of the tentacular and the outrageous. Lush must be trimmed down to demure. Wild must be harnessed *. Amazingly, they do find ways to win the war against barbarous nature (they have won many wars) and one of them is to assemble the staghorn ferns into a crown so they have less of a jungle look and more of an urban, polite appearance.
Annoyed but not defeated, I sauntered back to the hothouses where normal plants are sold at normal prices. I have been avoiding the nepenthes shop showing off rows of red pitchers locally called 'teapot covers' (nắp ấm). Soon, however, I realized that nepenthes alatas grown upside down and untrimmed looked very much like an epiphyte. I made up my mind to buy two of them for a paltry sum in the hundreds of thousands instead of millions dongs.
Lunch was a quick stop-over at a sandwich booth. In LA where my sister Thanh lives, the local Vietnamese sandwich booth is the Nom Nom truck. This one is the Rolls-Royce of banh mi micro-trucks serving exclusively crunchy lacquered pork suckling.

When I got home a party was going full blast at the neighbors', the Dôngs (who sold me the land). I declined the invitation to join them but accepted a plate of sticky rice cooked in momordica cochinchinensis, a vine fruit flaunting bright red flesh looking like bloody human flesh.
The occasion was giỗ, some ancestor's death anniversary. It is the sole occasion for a gourmet celebration in this country—other than weddings (weddings are not recurrent, at least not traditionally). Daughters and daughters-in-law were up since four in the morning to prepare the feast.
Today, I woke up early (not at four) and planned to go back to Danang for more nepenthes or fern shopping but the sky is gloomy and rain is threatening . Instead, I sat down and got this blog started.
My back wall has gorgeously improved and the air-conditioner piping much less conspicuous. Am I  really supposed to feed flies to the plant? Breed flies?

This a vertical garden I spotted the other day during my roamings on the bike.
