Plant ofthe Month
Origanum vulgare L.
Oregano (Origanum vulgare) is a sprawling woody shrub which can grow up to 1 m tall. Popularly used as culinary herb in Italian cuisine, dried Oregano leaves are also used in traditional medicine for treating colds, indigestion and upset stomach, because of the high carvacrol and thymol content naturally found within its essential oil. The plant is easy to care for, best grown in full sun and well-drained soil.
Animal ofthe Month
Nycticebus coucang (Boddaert, 1785)
The critically endangered Sunda Slow Loris is the only venomous primate in Singapore. It produces a yellow secretion from glands on the insides of its elbow, which combines with saliva to form venom. During the day, it sleeps on branches or in tree holes by tucking its head into its belly and rolling into a ball. Globally, the population size of Sunda Slow Loris is decreasing due to habitat loss and illegal pet trade.)

Sticky Situation
Drosera paradoxa (Sundew) falls under the largest genus of the carnivorous plants – Droseraceae. Despite the lack of a physical trap like the Venus fly trap, the Sundew attracts insects with nectar and its brightly colored tentacle-like structures. The Sundew responds to the presence of prey on its sticky specialised leaves by catapulting its tentacles towards the center of the leaf. The sticky tentacles contain digestive enzymes that slowly digest prey, leaving only the exoskeleton. Researchers reported that once the tentacles have flung inwards, they cannot be unwound or used again. Fortunately, many new leaves are produced every few days so the Sundew can set new traps for unsuspecting insects. Click on the button below to learn more.

Bred for bracts!
What could Bougainvilleas, Heliconias and some of the Bromeliads have in common? While Bougainvilleas may not bear any resemblance to the latter two, the answer is evident in the colorful ‘flowers’ – the most eye-catching, visible structures are in fact not flowers, but bracts or modified leaves that subtend the true flowers. The true flowers are often rather small in comparison to the bracts(or less colorful, in the case of the Bougainvilleas), and it is thought that these plants have developed the colorful bracts in order to better compete for the attention of pollinators and increase their chances at being pollinated. Gardening enthusiasts too are attracted by the colorful displays, and many new varieties and hybrids of these plants are being bred by horticulturists for more novel color tones and combinations.

Colour-changing magic
Commonly known as Butterfly Pea plant, the flowers of Clitoria ternatea is one of the key ingredient for the colour changing drink which is taking over the world by storm. Dried flowers are boiled to produce a blue solution, and it changes to purple when lemon juice is added! In traditional Peranakan culture, the blue pigment is also used for popular dessert like Kueh Salat. Butterfly Pea plant is widely cultivated in home gardens and the roots can improve soil quality by fixing nitrogen. Click on the button to learn more.

The Gelam Tree
Do you know that Kampong Glam derived its name from the gelam tree (Melaleuca cajuputi)? Kampong Glam was named after the gelam trees that were growing or planted in the area. ‘Kampong’ refers to village in Malay and ‘Glam’ (or ‘gelam’) is the common name for the tree Melaleuca cajuputi, a tree from the myrtle family (Myrtaceae). This tree has a distinct papery bark and has many medicinal uses. Kampong Glam used to be just by the sea and the gelam tree had many practical uses for boat building by the Bugis sailors! Although the gelam tree is extinct from the wild in Singapore, it still widely planted and cultivated in the urban areas of Singapore. You can even see some fine specimens planted in Kampong Glam!

Traveller’s Palm
Did you know that the Traveller’s Palm (Ravenala madagascariensis) is not a true palm? It belongs to the Strelitziaceae family and it is a close relative to the Bird of Paradise plant (Strelitzia reginae). Native to Madagascar, the Traveller’s Palm is popular in tropical landscape because of its enormous leaves which are arranged in a fan shape. It produces big, erect inflorescence like that of Heliconias. However, it seldom blooms in Singapore due to the wet weather. Its fruit are brown capsules, enclosing numerous seeds covered with bright blue arils.

View AllHow do mangroves get their nitrogen?
Life is tough for mangroves. They are faced with muddy anaerobic soil and daily tidal inundation, resulting in very nutrient poor soil, especially nitrogen – one of the key element for growth. Scientists were curious how mangroves cope with this environmental challenge, and solved the mystery when they found diazotrophs living with the trees. Diazotrophs are soil-dwelling micro-organisms that convert atmospheric nitrogen into ammonia, which are deposited in the soil, for the tree to absorb. The researchers documented the mutualistic relationship that mangroves share with diazotrops, and how the roots influenced the development of the microbial community.

04 Mar, 2020The largest ever Rafflesia found in West Sumatra
A recently bloomed specimen of Rafflesia tuan-mudae in a West Sumatran forest is the largest blooming flower ever recorded with the diameter of 111 cm! Curiously, it was found in the same location as the host plant that produced the previous largest Rafflesia with diameter of 107cm, in 2017. The Rafflesia plant is a parasitic plant without roots or leaves; it feeds on water and nutrients from its host plant to live. This is why the plant is often referred to as a "monster flower" for its parasitic properties and foul odour similar to rotting meat. Click the title above to read more.
03 Feb, 2020Flora of Singapore
The Singapore Botanic Gardens is spearheading an important and botanically meaningful project; Flora of Singapore, a catalogued description of all the plant species that can be found locally. Featuring more than 3000 species, three volumes have been published and the full project will take botanists the next 10 years to complete. Flora of Singapore is the first comprehensive effort, following in the footsteps of the great works of Henry Ridley’s Flora of the Malay Peninsula (1922-1925). With collaboration from experts worldwide, the first three volume were published in 2019, and is a great resource for formulating conservation policy and future reintroductions.
