This is the last part of my photo blog on 20th WOC Singapore 2011. The WOC organizer have put up a well presented wall panel with detailed write-up and photographs that describe the various native orchids of Singapore.  

The featured orchids are: Arachnis hookeriana, Bulbophyllum blumei, Bulbophyllum medusae, Coelogyne mayeriana, Dendrobium leonis, Grammatophyllum speciosum, Bromheadia alticola, Bulbophyllum clandestinum, Bulbophyllum membranaceum, Bulbophyllum pulchellum, Bulbophyllum singaporeanum, Cymbidium bicolor subsp. pubescens, Cymbidium finlaysonianum, Eulophia spectablis, Liparis ferruginea, Neuwiedia veratrifolia, Plocoglottis javanica, Robiquetia spathulata, Thrixsperum amplexicaule, Bulbophyllum vaginatum, Vanilla griffithii, Arundina graminifolia, Dendrobium crumenatum and Spathoglottis plicata.

Some of these beautiful orchids may either have extincted due to urbanization, or may have been re-discovered and/ or re-introduced back to our trees in the recent years.

Theme of 20th WOC 2011

I have attended the 20th World Orchid Conference (WOC) held on November 2011. This memorable orchid show is truly the event of the year, as the last WOC held in Singapore was in 1963 (48 years ago!).  

Unlike the previous Singapore Garden Festival that was held at Suntec Convention Centre, WOC was held at Sands Expo and Convention Centre.This was the first time Sands Expo held a orchid event.

This small sized orchid have been growing at the bright spot of my balcony since July 2010. This is the plant first flowering in the month of October 2011. The flowering may have been triggered by temperature drop for the past days in Singapore, due to the sudden heavy rain coupled with strong Northeastern wind.

External Courtyard at Odeon Towers (Singapore)

Odeon Towers (Singapore)
This is my second post on landscape design. My first post on the landscape topic was posted earlier on February 2011. In this post, I wish to feature an external courtyard at Odeon Towers, located in the city hub of Singapore. 

Odeon Towers is a 23 floors mid-rise office tower along the bustling North Bridge Road. The tower is located within walking distance from the National Library, Bras Basah Complex, Chijmes and City Hall MRT Station. The tower has been around for the past 15-20 years and was last renovated in Year 2007. 

The renovation includes new landscape design for the external spaces around the office podium (refer to my sketch plans below). 

Bulbophyllum plumatum

Bulbophyllum plumatum [1]

Ames 1915

Section: Cirrhopetalum

This strange looking orchid also known as 'The Feathery Bulbophyllum or '紅絲帶' (which means red ribbon in chinese). However, I would prefer to call it 'The Red Lantern' or 'The Red Chilli' in my own term. This warm orchid is native to Malaysia, Indonesia as well as in Philippines. 

I have been growing this bulbophyllum since January 2011 along window area at my kitchen yard. The yard receives less indirect sunlight but strong prevailing south-western wind during June-July. Due to the windy condition and as the plant is mounted on a fern bark, I watered it in the morning and evening to increase humidity.

This bulbophyllum has flowered for the first time in mid July 2011. The plant's  budding/ spiking stages are as follows:

Brassocattleya Wonder Star (B. nodosa x Bc. Morning Glory)

Brassocattleya Wonder Star

First registered: 6/6/2001

Parentage: Brassavola nodosa x Brassocattleya Morning Glory

Section: Cattleys Alliances Hybrids

This attractive orchid hybrid, Bc. Wonder Star has been made by backcrossing Brassavola nodosa into Brassocattleya Morning Glory. See below:

Brassocattleya Wonder Star = Brassavola nodosa x Brassocattleya Morning Glory

Brassocattleya Morning Glory = Brassavola nodosa x Cattleya purpurata

Section: Cestichis

This young orchid have been savaged previously from the mother plant that has suffered from basal rot around 2-3 years ago. The mother plant eventually died off, but fortunately this young offspring with 1-2 back bulbs have manage to re-establish itself on a small piece of wood mount. Although the plant have survived, its growth have been stunned and only managed to produce 1-2 new bulbs recently. 

I have added a small amount of moss around the root area and placed the wood horizontally to retain some moisture. The plant was watered sparingly in the morning and evening to prevent the re-occurrence of basal rot.

(Teijsm. & Binn.) J.J.Sm. 1912 

Section: Cirrhopetalum

This is my second bulbophyllum putidum that I have taken care since Jan 2010. My first bulb. putidum was featured in my earlier blog post in April 2011. 

This orchid was originally planted in a plastic pot filled with perlite and top dressed with a layer of sphagnum moss to retain moisture. The plant has produced 2-3 new pseudo-bulbs over the year (total: 7-8 bulbs). It finally flowered from one of the latest bulb in June 2011.

In term of cultivation, I provided this plant with the same care as per my first bulb. putidum:

1) Sunlight: Bright indirect light.

2) Water: Once daily in the morning and second watering if I am available in the evening.

Perhaps the other bulbophyllum has been kept more on the drier side compared to this plant, as the former orchid is mounted on a small wooden twig.

Brassocattleya Morning Glory (B. nodosa x C. purpurata)

Bc. Morning Glory is an attractive intergeneric orchid primary hybrid including the genera Brassavola and Cattleya.

Brassocattleya Morning Glory 

First registered: 1958

Parentage: Brassavola nodosa x Cattleya purpurata
Section: Cattleys Alliances Hybrids

This beautiful orchid hybrid has inherited its large starry-shaped flower form and delicate margenta-veined lip from Catteya purpurata; the improved rounded heart-shaped lip from one of its parent, Brassavola nodosa.

Papa
Brassavola nodosa is a warm-hot lowland growing species, native to Mexico and Central America. Each medium sized psuedobulb with 15-20 cm long sub-terete leaf is capable of producing between 1- 6 whitish flowers with a spread between around 7.5 -10 cm. The flowers only emit its citrus fragrance after the nightfall, hence give rise the common name, 'Lady of the Night'.

Dendrobium discolor 'Rigo Twist'

Dendrobium discolor 

Lindley 1841 

SECTION Spatulata

I have been growing this beautiful Dendrobium discolor along my balcony since April 2010. This hot growing lowland orchid species can be found from Australia to Papua New Guinea. The plant can grow at least 2.0 m high in its natural habitat. This all year round bloomer can produces an average of 40 brownish yellow flowers on a 50-60 cm long spike. The flower measures 4 cm wide.


The featured plant, Dendrobium discolor 'Rigo Twist' is considered a dwarf form of the species:
i)   As its height is only 15-16 cm tall;
ii)  Each flower measures 3 cm wide x 2.5 cm high. The flower spike is about 15-16cm long.

I am quite surprised that the orchid managed to bloom at my balcony which is partially lit up for 2-3 hrs during the day. 

Bulbophyllum sp (Unknown I.D)

Bulbophyllum sp

I'll like to share photo of this beautiful unknown bulbophyllum from a local nursery recently. According to the owner, the orchid is from some place near PNG.

It appears similarly to Bulbophyllum lepidum, but I am not entirely sure about the I.D. Perhaps someone can help to identify it please? Thanks in advanced.

Pelatantheria rivesii
