A beautiful white bauhinia at HortPark

On one side of the Vistor’s Carpark at HortPark, there are several bauhinias with spectacular white flowers that are trained up the arbours there. The plants are rather dwarf-growing, which are quite unlike the purple flowered relative, Bauhinia blakeana, that grows into a tree.

These shrubby, white-flowered bauhinias are most likely to be Bauhinia acuminata. It is native to this part of the world and there is not much to wonder why it grows so well under our local climate. It is a rewarding to grow here locally and people here should buy one to plant in their gardens.

From the picture above, it is obvious that the Bauhinia acuminata is quite a generous bloomer. Each blossom is about 8 cm in diameter, with petals that are blunted at their tips. When a light breeze blows, the flowers dance along with it and can be likened to a swarm of white moths fluttering through the area. They stand out obviously against the green foliage and imparts a different feeling compared to the more common orange-flowered Bauhinia kockiana that is often used to climb up and cover similar structures.

Like most other woody flowering shrubs, Bauhinia acuminata needs to be grown in full sun for profuse flowering. Being forgiving shrubs, they can still do well when grown in partial shade – in HortPark, these plants are growing under the encroaching canopy of a taller tree above.

It must be grown in well-drained soils that can retain some moisture at all times. They should never be allowed to dry out and should also be feed regularly. As plants grow, the branches can get a little heavy and may droop and they may benefit from an occasional pruning to keep them in good shape and the right size. Pruning will also help to keep the plant vigorous as well and prevent it from getting straggly.

Tower Tree in Flower!

The Tower Tree (Schizolobium parahyba) is now a common candidate for landscaping in Singapore. Once considered an exotic plant, we can now see it everywhere, planted around condominium showflats, in public and private gardens. Due to its umbrella-like canopy with pinnate leaves, a small plant at a height of just 1m makes a good substitute for the tree fern. It is also known as the Brazilian Fern Tree.

A member of the bean family, Fabaceae, its common name is descriptive of its growth habit. The Tower Tree is a plant from Tropical America and it can grow up to a towering height of more than 5 storeys! Plants are usually sold in local nurseries and planted are single trunked. Those that are branched are increasingly becoming popular and sought-after due to their unconventional look.

I stopped short of growing this tree in my community garden for an obvious reason – the tree is so tall and I felt it will become a lightning hazard. I don’t want anyone or the tree to be hurt!

Last Saturday, when I was at HortPark for its opening, CEO NParks, Mr Ng Lang, pointed to me a Tower Tree that was flowering. It was located at the visitor’s carpark and I must say this is my first time that I witnessed the flowering of this ornamental tree. I grabbed the opportunity to take the picture of this rare occurrence.

Hayley’s Visit

Hayley paid a visit to my community garden this morning. She is a Singaporean who is now residing in the UK. She got to know about the garden via the BBC program “Around the World in 80 Gardens.” Hayley (a very nice cheerful name, I feel) is also a edible plants gardener like me, who takes part in Singapore’s community gardening equivalent in the UK. Over there, it is called allotment gardening.

In this visit, Heyley was accompanied by Kelly and Ephrem. Incidentally, Kelley works in NParks and she was surprised to know her visit today was to my community garden. It was a small world indeed!

I then took them on a tour around the two community gardens, namely, the kitchen garden and the tropical ginger garden, that are under my charge. It was a personalised tour that lasted almost 2 hours. I apologise for the duration, as well as, the sun that was shining above our heads. A fast and rushed garden tour will mean we would be missing out on a lot of interesting plants and sights.

I hope the tour was enjoyable one for all. The conversations we had were indeed enjoyable and although this was the first time we met up, I felt as if we were close friends. Perhaps it was because of the common interest that we all shared.

It was past noon where we then sat down in the Residents’ Committee office for a rest before adjourning for lunch at Hougang Mall. Many thanks to Hayley for the treat at Ajisen for lunch, as well as, for the cherry tomato seeds. I hope the bag of vegetable seeds will be a surprise for her allotment gardening friends back at home.

Official Opening of HortPark (10 May 2008)

The long-awaited opening of HortPark finally took place. The gardening hub of Singapore was declared open this morning, which was a cool but wet one, by our Prime Minister, Mr Lee Hsien Loong. This opening was done in conjunction with the opening of the bridges that link up the Southern Ridges.

I am honoured to have been invited on stage to be part of the official opening ceremony this morning, together with Mr Veera from Landscape Industry Association of Singapore (LIAS). We are the only two non-governmental individuals who were on stage. Mr Veera represented the ‘private sector’ while I represented the ‘people’ because I do community gardening and promotion of gardening to the masses.

Those constitute the two P’s of the 3P Partnership Programme that is a collaboration between the people, public and private sectors. The government officials make up the last P which is the ‘public’ sector which consists of our Prime Minister and his colleagues, as well as, members from the National Parks Board (NParks).

On stage, we held watering cans that were made by students from recycled materials and we then watered the plants located in front of the stage to officiate the opening of HortPark. The plaque that commemorated this day was unveiled after that by the Prime Minister.

For this event, we have also been invited by NParks to set up a booth to showcase the Green Culture Singapore website in HortPark’s multi-purpose hall. It was quite last minute as we have been sent the request just a week before the event.

Thanks to Phillipe, my new but reliable yet creative team member, who squeezed his brain juices for a low budget concept and rushed day and night to come up with the materials required for the booth decor. On Thursday night, Phillipe, Albert, Chong Ren and me were at Phillipe’s home in the night to rush up the production process. Albert and Phillipe continued on to finish up what’s needed into the wee hours of the morning. I had to leave because I got to work the following day.

I am thankful to the efforts put in by Phillipe, Albert and Chong Ren. I am very pleased with the final outcome as well as the concept of the display, which was quite novel for a gardening-related discussion forum and website. I did not want the usual, clinched look which is the type that at one look, people can already expect what you are trying to showcase.

In our display, Phillipe used paper bags to form up the background which contained labels of the specific names in Latin and English that are commonly found in the binomial nomenclature of plants. That was aimed to add some understanding to the botanical names of plants. In one of the rows, we had some of our feature articles written by me and fellow Green Culture Singapore members for visitors to browse.

The riser on the left exhibited some of the handicraft work done personally by Phillipe. The idea was to showcase how one can enjoy plants and gardening via artistic expressions like painting motives of wildlife and plants on things like a plate and wooden gift boxes.

In the center, we have a very realistic staghorn fern that was made out of paper, which represented the Green Culture Singapore’s discussion forum. The staghorn fern is an epiphyte, which is essentially a non-parasitic plant. We all know that staghorn ferns in Nature are ant hotels and ants have a symbiotic relationship with the fern where the fern provided the ants with shelter while the ants brought food for the plant.

Green Culture Singapore, like the staghorn fern, is here to help gardeners and not to overshadow anyone. The forum serves as a convenient and conducive platform for gardeners to learn and share their gardening experiences and the members’ active participation and generous sharing of knowledge are essential for the success of the forum. With time, the forum’s knowledge base builds up and benefits all members, particularly those who are starting out.

On the right riser, we have more information on pictorial charts to tell people about what we do as well as a small display to showcase some culinary gingers that people should grow. These included two common ones like the flowers of the Torch Ginger and Turmeric and another rather uncommon duo like the Chinese Key and Lesser Galangal.

Everything was completed and put up on Friday morning. But I was quite disappointed to find out in the end that our Prime Minister did not have the time to pay a visit to the booth we have put up. I think the other industry partners who were present felt the same way too.

The Chinese Hat Plant

When I was in HortPark late last year for GardenTech 2007, I was surprised to see a flowering shrub that bear orangey flowers shaped like an interesting way. The plant, apparently, is not a commonly grown plant in our local streetscape. Hence I am not surprised to see its absence from the 1001 Garden Plants in Singapore book by NParks.

Just yesterday evening, I happened to be browsing a book at the Orchard Road Kinokuninya bookstore and pounced upon a profile of this plant. I breathed a sigh of relief and told myself, “Ah… I have found the identity of this plant. At last!” Knowing the exact and correct botanical name of a plant is important, I feel, because it can help us to understand the plant and its growth requirements better.

A member of the Verbenaceae family, this flowering shrub is known by a number of common names, all inspired by the appearance of the flowers – Chinese Hat, Mandarin’s Hat, Cup and Saucer and Parasol Flower, depending on how you want to imagine the flower to look like. Botanically, it is known as Holmskioldia sanguinea. The cultivar grown in HortPark’s Flower Walk appears to be ‘Bronze’.

The plant is a scrambling shrub and hence not a well-behaved tidy plant. It calls for frequent pruning to keep it in shape and form. If left on its own, it can become a straggly eyesore. On the other hand, the long, trailing stems also make the plant suitable for growing over planter boxes.

The flowers are prominent as they appear in dense clusters and luckily, the plant’s small oval leaves do not fight with the flowers for attention. There are also yellow- and bronze-flowered forms.

Like most woody flowering shrubs, Holmskioldia sanguinea prefers to grow in full sun. Direct light is essential for its flowering.

Green Culture Singapore’s HitWise Award 2007 Win and Feature Articles for April 08

I was pleasantly surprised to hear that Green Culture Singapore, the gardening website that I have set up, won the HitWise Award for the House and Garden industry for the Year 2007! This is a significant milestone for the website as this is its first win in almost four years after it was set up. It is a recognition of our efforts! Our happiness and thanks are all written inside the first feature article below:

Green Culture Singapore, A HitWise Online Performance Award Winner 2007

Green Culture Singapore (GCS) was announced as the #1 website in the Lifestyle – House and Garden category for 2007, in the latest Hitwise Online Performance Awards program. The annual Hitwise Online Performance Awards recognises excellence in online performance through public popularity, awarding websites in a variety of industries. Read on to find out more!

Another article was penned by one of the carnivorous plant growers from the GCS discussion forum, guqin. He specialises in Utricularia and more information about this genus of interesting plants can be found in the article below:

Plants with Bladders!

Carnivorous plant growers refer to the Utricularia genus of carnivorous plants affectionately as ‘pond scum’. While ‘pond scum’ rightly refers to filamentous algae, some Utricularia species, especially aquatic ones, when not in flower, do resemble ‘pond scum’. However, these ‘pond scum’ do produce flowers that are disproportionately beautiful from their vegetative self and here lies their attraction. Read this article written by S. H. Tan (a.k.a. guqin on the GCS discussion forum) to find out more!

The next article, as usual, was penned by myself. This month, I wrote about the mock strawberry which is also known by another name, the Indian strawberry. I find that little is known about this plant and not many Singaporeans are aware of it. Hence I decided to do some research and wrote an article about it to let readers to learn more about it. I grow this plant in my community garden and many visitors who visited the garden were quite surprised to see a ‘miniaturised’ strawberry plant.

The Neglected Mock Strawberry

The mock strawberry plant is an attractive, miniaturised version of the edible strawberry plant. It exudes some charm but seems that it is not commonly grown or popular amongst gardeners due to the belief that it can be an invasive plant. In this article, Wilson shares some tips on how one can appreciate this dainty plant whilst still able to exert some control to confine the wandering stolons of this plant.

The Community Garden Update

The cool and wet season that lasted two months (March and April) was just over. Now, the hot and dry season is back and I think this will last until mid-August.

I dread it. Everyday, when I wake up, I see the sun and I reckon most of us are starting to dread it. The heat is unbearable for both humans and plants! I had to make it a point to water my plants more often – the wet season earlier had made me a lethargic and lazy gardener!

The community garden that I lead currently looks quite good, judging from the pictures I took yesterday morning. The amount of great dedication that my passionate community gardeners has for their plants shows in these photos. To me, happy plants equate to happy gardeners and this is what I am looking for in my community garden.

Regular watering must be done during this time and must be done at least twice daily, once in the morning and another later in the evening. Fertiliser was also given to the plants on a weekly basis. Edible plants are quite nutrient-hungry and any lack of food will show up quickly via the manifestation of slower than normal growth!

On the ornamental plants side, the Yellow Bells tree, affectionately called “Mrs Lim’s Tree”, is covered with golden yellow blooms now and the surrounding cannas are also looking at their best, without a trace of rust or fungus on their leaves. The Japanese honeysuckle hedges are also picking up after their recent hard prune.

The garden, viewed from the back.

The vegetables grown in the beds behind are also doing amazingly well as growth is now quite fast. Thanks to the fertiliser and water that are regularly supplied to these plants by my gardeners and not to forgetting to mention, the incessant sunshine that is now available.

The lady’s finger plants, at about 1 and half months old, have started to flower and set fruit.

An unidentified Brassica relative, a popular leafy cut-and-come again vegetable in community gardens here. It grows upright and never seems to blot! The self-seeded amaranthus plants in the same bed are also doing exceptionally well!

A bed of lush Chinese Spinach – many of the gardeners cannot bear to pick them for food!

Up, up and away – the climbing French Bean vines are climbing their way up the strings. A couple of vines have started to flower.


My Indonesian Wax Ginger in Bloom!

This is the first time that my Indonesian Wax Ginger plant flowered for me since I bought and planted it in my Ginger Garden last April. That was quite fast actually because I reckon I purchased quite an established plant to start with.

The clump has started to bloom some time back, at least a month ago, but I posted this little piece of good news now because I wanted to wait for the blooms to develop to a stage that is good for taking pictures.

Three of the four flower spikes, in various stages of development, are pictured here.

Botanically known as Tapeinochilus ananassae, the plant is native to this part of the world all the way until northern Australia. It belongs to the Spiral Ginger family, Costaceae.

My plant is slightly taller than me at about 2 m now and I love its decorative bamboo-like stems. As expected from a relative of the spiral ginger, the leaves of the Indonesian Wax Ginger are also arranged in a spiralling manner along the stem.

What is the most attractive feature about this plant is its terminal, extremely durable inflorescences that are shaped like a cone, which are used in some exotic flower arrangments. The cone rises out from the base of the plant out of the ground. It grows on a thick stem that can rise up to 2 to 3 feet above the ground before opening up to reveal the bright crimson waxy bracts where the brigh yellow waxy flowers emerge.

A flower spike just starting to open up…

Another flower spike with bracts that are more obvious now. One can see the yellow true flowers hiding between the bracts.

Ah… A beauty at last with a well-formed column of bracts arranged on a cone-like structure. It can grow taller still!

So far, all those pictures of the inflorescence were taken from the side. When viewed from the top, the inflorescence looked like a rose!

Root Awakening (3 May 08)

The first of the two Root Awakening columns that was published on the Straits Times today. Enjoy!

I guess the hot and sunny season is back in Singapore again. Looks like it is a time where the Japanese Rose, Portulaca grandiflora, will look its best! Take note that this plant is not related to the true rose flower!
