Summer Movies 2021: Around the World in 80 Gardens – South East Asia

 This summer I'm heading to the movies to enjoy some of the world's most beautiful gardens. My travel partner and guide is British garden guru, Monty Don, and the movies are his horticultural travelogues from the BBC series "Around the World in 80 Gardens". Recall we traveled with Monty several years ago (see Summer Movies 2016: Australia and New Zealand). Then, we explored locations with a Mediterranean climate; this year we're broadening our horizons to several exotic locations (blame it on the pandemic)! I'm hoping to have some fun, and learn more about movie star plants and gardens from these different locations. Grab your sunscreen and a hat, and join us for some summer travelling!



Bangkok, Singapore, and Bali (2008, Episode 10)

Today we head for Southeast Asia, where Monty's quest is to find the perfect tropical jungle garden that has served as a model for Western gardeners, since the nineteenth century. He starts in Bangkok, Thailand by visiting Jim Thompson's Garden (an American entrepreneur who thrived in the Thai silk industry, and then disappeared into the jungle in 1967). He built an estate and tropical garden in the heart of Bangkok using palms, gingers, lotus, water features, and Thai hardscape. It was his vision of what a jungle could be, but not necessarily an indigenous Thai garden.

Next Monty visits the Thai Grand Palace Garden, where he is surprised by lots of topiary, and then the Chitralada Royal Villa, where the king uses the grounds to experiment with sustainable food production for his subjects, growing different crops such as mung beans, peanuts, and rice. Monty notes that the garden focuses completely on the practical and not on aesthetics. Its lab studies how to preserve Thai's indigenous plants (in the past, you would not cultivate a jungle, rather try to fight it back). 

Finally he visits the Khlong Gardens along the canals and waterways of Bangkok. Plants are everywhere, including those used to flavor food. His guide, actress Patravadi Mejudhon, informs him that people want the plants, but don't necessarily want to garden - it's too hot! Monty reflects over stir fry in the evening that the exotic may be what we can't grow, more of a state of mind than a garden style. In Bangkok, gardens grow so fast that that there isn't really a style - it is just whatever grows!



Next, Monty travels by train south to Singapore. Forty-plus years ago Singapore started a campaign for the greening of the city. Singapore had grown so fast, it had become a "gray jungle" of concrete. The goal was to turn the city into a garden. Gardens, parks, and recreational spaces were developed on a large scale, and citizens were encouraged to garden. Monty interviews Minister Mentor Lee Kuan Yew and Dr. Lawrence Leong Chee Chien, both influential in the movement to green Singapore. He also interviews blogger and activist, Wilson Wong, who promotes Community Gardens for growing food. Monty leaves Singapore without finding his model tropical jungle garden, and a little depressed by all the orchids in the Singapore airport (we may part company here).

Monty flies to Bali to continue his quest for a local jungle garden. The predominate religion is a version of Hinduism that reveres nature. He visits a temple garden first, in which every plant and flower has meaning and is used in temple offerings. Monty is overwhelmed with the peace and serenity of the place. Later, in the night market, Monty sees flowers and petals for sale (the ingredients for making offerings), and notes how the spiritual is intertwined with commerce. Monty visits the garden of a mutli-family compound, and observes this same intertwining of the useful and the spiritual. He ponders whether this is really a garden.

Monty visits an estate garden, right on the beach, and concludes it fulfills all the fantasies of what Westerners want in a jungle paradise (sanitized, without any chickens wandering around). He ends his tour in the garden of Made Wijaya, a landscape architect and designer from Sydney, Australia. He specializes in tropical gardens, and blends the ancient and modern in what could be called, the Bali style. He uses color, plants, shrines, and history in his designs, to create beautiful and distinctive gardens. Monty concludes the tour with the idea that tropical jungles may be a figment of our imagination and a vacation fantasy. Mankind will always be in search of Shangri-La, but it exists only within ourselves.

I really enjoyed seeing the lush gardens of Bangkok, Singapore, and Bali, whether or not they are authentic, indigenous, or a true garden. Maybe that's the result of gardening in a dry climate, on the brink of another drought cycle. The green exotic plants and abundant water do seem like Shangri-La!

Dye Project: French Broom

Back again with another dye project, using dye sources from our residential lot here in Oakland, California. This year we're going "back to the land" to discover what resources are available to us from our own place. Last time we dyed with Tulip Tree flower petals, which produced a lovely lemony-yellow dye (see Dye Project: Tulip Tree).

Today I'm dyeing with French Broom (Genista monspessulana). French Broom is a woody shrub that is native to the Mediterranean region. Broom is a nitrogen fixer that does well in poor soil, and is a prolific seed producer.
  

 


The flowers are an intense yellow, and quite beautiful, but French Broom is highly invasive in the United States. The shrub can quickly overrun native vegetation, providing little benefit for the local wildlife.

My research on this species of Broom indicates that leaves yield a green dye, but I found little about the flowers, or a combination of leaves and flowers. Other research indicates that Scotch broom yields pale yellow or beige, but Dyer’s broom yields brilliant yellows and yellow greens. We have a self-seeded French Broom bush at the edge of our property. I have started to eradicate it, but decided to experiment dyeing with the flowers that I removed.


Self-seeded French Broom


For this project I used basic dye equipment, and a well-ventilated workspace. I used a soaking pot, a dye pot, a heat source, and a candy thermometer to keep the dye bath at a consistent temperature. I also used a strainer and cheese cloth to remove the petals and leaves from the dye bath.


Outdoor studio and basic equipment

Prepared fabric


The Weight of Fabric was about 11 ounces (312 grams), which includes:
  • 2 dish towels - 154 g (4.9 ounces) 
  • 2 napkins - 50 g (1.76 ounces)
  • 2 large handkerchiefs - 35 g (1.2 ounces)
  • 2 small handkerchiefs - 20 g (.7 ounces)
  • 1 dish cloth - 57 g (2 ounces)

French Broom blossoms and stems


The fabric was scoured and mordanted. I used a gallnut mordant, followed by a bath of 20% WOF alum and 8% soda ash as a brightener. This differs from our usual values of 15% alum and 2% soda ash. I collected about 12 ounces of French Broom flowers and leaves, so, the WOF% for 11 ounces of fabric was about 109%. I gathered the flowers, and froze them to preserve the color until I was ready to dye.

The supplies for dyeing include:
  • 12 ounces French Broom flowers
  • 1/2 lemon (juice and rind)
  • A gallon of water (plus more as needed)
  • 11 ounces prepared cotton fabric 
NOTE: For safety, use a face mask and rubber gloves.

Extract Dye

First, extract the dye, using our basic process:
  1. Add petals and lemon to the pot.
  2. Simmer for an hour.
  3. Soak petals.
  4. Strain them.

Rinse the petals to remove dust and insects, and then add the petals to a gallon of water in a stainless-steel pot. Stir in the juice of 1/2 lemon and its rind. Bring the temperature to 160 degrees, and simmer for an hour. Note that my equipment isn’t that controllable, so I typically cook between 180 - 200 degrees. Your color results may differ if you are able to maintain a lower temperature. 

Stir lemon juice and rind into petals

Soak for three days


Soak petals and lemon rind for three days to extract all the color possible. Strain petals out of the dye bath using cheesecloth. Return the dye bath to the stainless-steel pot. The resulting liquor is pale yellow or amber, depending on the light, and has a noxious smell. A face mask and rubber gloves are recommended. I tested the pH to learn more. It registers at 3, which is quite acidic (and may be from the lemon).

Dye Fabric

Dye the fabric using our basic process:
  1. Add wet fabric to dye bath.
  2. Heat the dye bath and simmer for an hour.
  3. Soak fabric in the dye bath.
  4. Rinse and hang to dry.

Add wet, prepared fabric to the stainless steel pot, and simmer for an hour, keeping the temperature between 180 - 200 degrees. Stir periodically to make sure dye is distributed as evenly as possible. If necessary, add more water to cover the fabric. The color from this French Broom species is not very strong or dramatic. Let soak for an hour or overnight. In pursuit of saturated color, I let it soak for three days.

Simmer fabric in the dye bath

Rinse fabric in cool water


Squeeze out excess dye from the fabric. Rinse the fabric in cool water until the water runs clear. Run the fabric through the washing machine’s rinse and spin cycles, using cold water. Let the towels air dry. Two weeks later, wash the towels in pH neutral soap, like Synthrapol, and hang to dry. The resulting color is a very pale yellow. 


Hang fabric to air dry

Very pale yellow dye results (with some imagination)


The results are a little disappointing, but maybe it is for the best. I have no incentive to retain the French Broom plant, and can eradicate it without hesitation!

Plant Aquarium: Liquidambar

 The Liquidambar is thriving in the lower yard here in the East Bay. Its leaves are shaped almost like a maple leaf, and the leaves sometimes quake like an aspen leaf because of their long petioles. The tree is bare from January to late April (we often wonder whether it has died), and then puts forth it beautiful fresh leaves in May. In fall, the leaves turn red, providing wonderful fall color.


Liquidambar

Liquidambar (Liquidambar styraciflua) is a long-lived, deciduous tree that grows to 50 to 150 feet (15-45 m) tall at maturity. It is also known as American sweetgum, and is native to the southeastern United States, and regions of Mexico and Central America. It is not native to California, but grows well as an ornamental plant. It is a nitrogen fixer and can tolerate various types of soil, including our clay soil.


Liquidambar in early summer

Liquidambar leaves are star-shaped with five long-pointed, saw-toothed lobes and long petioles. The brown bark is deeply furrowed into narrow scaley plates or ridges.  Young trees have long, conical crowns; while mature trees have round, spreading crowns. Liquidambar is monoecious with the male flowers in several clusters and the female flowers hanging at the end of the same stalk. The tree begins to produce seed when 20 to 30 years. The ball-shaped fruits contain many individual seed-bearing sections. So far our tree does not produce seeds that I can tell, which means it is still young or I have not identified the tree correctly.


Liquidambar in fall


I value our liquidambar tree for its lovely green leaves, lacy shade pattern, and fall interest. Learning that it can grow up to 150 feet tall, live for 400 years, and be a fire danger when planted less than 15 feet from a structure does give me pause. I'll definitely confer with our arborist for recommendations about shaping the tree and possibly lowering the crown. In the meantime, we can enjoy its loveliness in the landscape.
