Easter Gardening Talk @ HortPark

Yesterday, my colleague, Jin Hong and I, collaborated to give a talk that tied in with the Easter theme at HortPark’s Leaf Room. The talk was part of the “Easter Eggstravaganza” event that was organised by HortPark. Despite the small turnout, participants who attended the session found the ideas that we shared with them on how to use eggs in gardening useful and interesting.

Jin Hong shared with our audience on how one play a part to save the environment by using eggshells as containers that can be used to raise seedlings instead of using peat pellets and pots which derive their raw material from peat bog habitats. Eggshells can also be decorated like Easter eggs and used as a novel container for growing small plants. Containing mostly calcium, eggshells are a rich source of calcium that can be added to the compost heap and soil in the garden and potting mix for plants.

For my part in the talk, I shared with our audience that they can actually use bird’s nest ferns as ‘living’ containers for celebrating Easter in the tropics. Most of us use rattan or bamboo baskets to put our decorated Easter eggs. While researching on the topic. I realised that there are similar-looking but different species of bird’s nest ferns. Before the talk, I went around the nurseries to take a closer look at the different bird’s nest ferns on sale so as to be able to share my findings with the participants.

After the talk, my colleague, Jin Hong, took over to bring the participants of the talk on a guided tour of the Lifestyle Corner. The time was made fruitful then because the skies outside poured heavily. Our audience also got to see the new feature at the Learning Corner, which now has a display of an array of decorated eggs as planting containers, as well as, various different uses for eggshells that we can think of, in the garden.

Besides just the uses of eggshells, visitors to the Lifestyle Corner in HortPark this month, will get to examine the various types of bird’s nest ferns that can be purchased from nurseries locally. Although they are all called “bird’s nest ferns”, these plants can be divided into cultivars coming from three main species, namely, Asplenium australascium, A. antiquum and A. nidus. The most common species we see perching on trees is in fact, A. australasicum, based on the appearance of the cross-section of its midrib.

Many thanks to Richmond Tan, one of my Green Culture Singapore forum moderators, who came to support the talk as well as to take the photographs shown on this blog post.

My First Gardening Talk as NParks staff

Valentine’s Day which fell on last Saturday was a memorable day. Although I did a gardening talk at HortPark that afternoon, it was not like the past ones I delivered previously. Thanks to Richmond, both my friend and moderator from my Green Culture Singapore discussion forum, who had helped me to snap the following photos that appeared in this blog, showed me donning on the National Parks Board (NParks) polo t-shirt. The talk that was entitled “Grow your own sweet heart” was one that was given by me in the capacity as an NParks staff member. 

The response of the talk observed last Saturday was an overwhelming one. I was told that over 70 people signed up for the talk and although there was a massive traffic jam that occurred during the afternoon, over 50 people managed to turn up in the end. Many of them were my gardening friends who came all the way to HortPark to support me. I must thank Kamisah for sharing with me her delicious homemade desserts. I was and still feel very touched now.

I am indebted to my forum members who have helped me in various ways to make this talk on the sweet heart hoya (Hoya kerrii) and other hoyas possible and interesting. Maggie lent me her sweet heart hoya plant which she grew from leaf cuttings she bought. Gan allowed me to use the pictures he took when his sweet heart hoya flowered. Lily  granted me her kind permission for me to use some of her pictures of hoya plants.

My fellow NParks colleagues also extended their helping hands as well. Cheow Kheng kindly provided new and nicely made Community in Bloom bookmarks which were distributed to the talk’s participants. Shirley helped by bringing them to my talk. My colleague from my team, Jin Hong, thought of new ways of painting sweet heart hoya leaves where she also shared them with my audience who attended the talk. My own colleagues from my section and the HortPark events branch had also put in a lot of effort to ensure the talk was carried out smoothly. I was pleasantly surprised when I saw my boss, Kartini, turned up at the Fruit Room to listen to my talk despite having just returned from a long working trip. Many, many thanks! 

After my talk, I went on to conduct my first guided tour of the Lifestyle Corner in HortPark which I have recently taken over its charge. My colleagues and I rushed over the course of the week to do up the place to ensure that its decor was realistic and one that the layman can easily replicate at home. This was my first attempt to decorate the Lifestyle Corner and I have to admit that it was a daunting task! I encountered quite a large number of difficulties during the process. Now I know what my predecessor had experienced. I can still recall how critical I was with the work he did earlier for the Lifestyle Corner. I feel so bad now.

If one had been observant, at the entrance of the Lifestyle Corner, we showcased a heart that was made from cutting out and bending wire meshes by one of my very creative colleagues, Lin Htet. In the showflat, a dozen of pots of Parade miniature roses formed part of the Valentine’s Day display. Parade roses, available in a handful of colours, are relatively heat-tolerant series from Holland that Singaporeans can try to grow in their homes if they have good light at home.

I hope those of you who took part in the tour find it useful and enriching. I welcome any feedback to help us improve.

A Double Beauty – Getting to know the Self-Peeling Banana

Just yesterday, I received yet another email message from Keneric Ng, a Plant Information Officer from the National Parks Board (NParks) of Singapore that shares with me an interesting sight he saw at HortPark. He witnessed the relatively well-known but intriguing habit of an ornamental banana, Musa velutina, where the skin of its ripe fruits has the ability to peel on its own to reveal the white flesh beneath.  

The specimen of M. velutina that is planted in the Floral Walk leading to HortPark.

Musa velutina is commonly known as the Velvet-Pink Banana or Self-peeling Banana. The common names, Keneric shared in his email, are so valid and explain it all. In fact, the Latin specific name ‘velutina’ has the meaning of ”velvety”. It is so named because the whole infructescence is covered with short trichomes (hairs), and naturally the fruits (i.e. banana’s skin) possessed the same velvety texture too.

Both are ornamental in their own right – M. velutina‘s inflorescence (left) and a bunch of purple, velvety fruits (right).

Musa velutina has two facets of beauty. First , it bears beautiful flowers that feature bright pink coloured bracts. They are held upright and contrast starkly against its jade green foliage. Second, unlike the many plain and green coloured fruits borne by many common ornamental bananas such as Musa laterita, M. coccinea (M. uranoscopus) and M. ornata, the fruits of M. velutina are pinkish purple in colour. A bunch of fruits can certainly can rival with its own flowers in terms of beauty and for attention from its grower.

The pink coloured inflorescence of M. velutina is extremely attractive.

When ripe, the fruits of  M. velutina curiously splits open to reveal the glaring white flesh inside. Musa velutina is a species banana and therefore has seeds, unlike the seedless hybrids that we encounter as cooking plantains and dessert fruits. The seeds of M. velutina are typical of a Musa as they are numerous, hard and black. 

The fruits of M. velutina that split – don’t they look like stars?

It is interesting to note that this is the only common ornamental banana that is seen locally that splits open its fruits when they are ripe. Musa laterita, M. coccinea (M. uranoscopus) and M. ornata are not noted to do this! Perhaps it is a way that this species of banana use to attract and invite animals such as birds to eat its fruits and help to disperse its seeds. The fruits that have split open are quite attractive on their own. The pointed flaps of the skin of an unpeeled fruit reflex backwards and that make each one of them look like a star!

The fruit of the Musa velutina – it is obviously very seedy!

The fruit of M. velutina is not exactly edible. Keneric did a taste test and shared that it is not because it is poisonous, but there are so many seeds in each fruit that makes each one of them really difficult to consume. The seeds are actually visible even without bruising the flesh of each fruit. Keneric described that eating a fruit of M. velutina is akin to eating a custard apple – he had to suck whatever pulp he can from the seeds. It is not exactly tasty but nevertheless, he picked up some mild banana-sweetness in it still.

 

A closer look at the numerous black seeds extracted from a ripe fruit of M. velutina

As Keneric was going around to document on the M. velutina at the Floral Walk of HortPark, many curious visitors, including a child with his mother, walked by and were fascinated by what they saw and they asked many questions such as ”Is that a banana? Why is it white? Does banana spilt? Are those seeds? (when they saw Keneric dissected the fruits on site).”

Keneric later passed some seeds to that inquisitive boy and told him to show his teacher the discovery he has made during his holidays. Being able to witness the pretty spilt fruits of  M. velutina already made his day and this little interaction with the boy kind of made it twice. As we can see, plants and gardens in Singapore have an important educational role to play, on top of beautifying the surroundings.

A Fragrant Shrub to Grow in Your Garden

The perfume flower tree, a little known relative of the familiar Tembusu tree (Fagraea fragrans) flowered in HortPark recently. I was notified via a short account that was written by Mr Kelvin Heng, a manager from the Horticulture Management section of HortPark that was sent to me via email. Many thanks to the National Parks Board (NParks) for sharing this piece of information with me, as well as, the readers of my blog.

Specimens of the perfume flower tree in bloom in HortPark.

As its common name suggests, the perfume flower tree, similar to the Tembusu, produces flowers that emit an extremely pleasant fragrance. The attractive, five-petalled, trumpet-shaped flowers are borne on a bunch terminally on each growth point. They are white when they first open which turn yellow on the following day before fading away subsequently. Each flower features rather prominent stamens, measures about 5 cm in diameter and has a long throat that can be as long as 10 cm long! After the flowers fade, very pretty fruits that are jade green in colour are produced.

The beautiful and fragrant flowers of the perfume flower tree.

The plant that was flowering in HortPark is planted near lamp-post number 1-3/4/3 along the Floral Walk. Botanically known as Fagraea ceilanica, the perfume flower tree is classified under the Loganiaceae family. This evergreen plant can be pruned back to maintain it as a manageable small shrub but if it is left alone, it can grow into a small tree with a height of about 20 m.  When not in flower, the perfume flower tree still makes a very attractive shrub because it has very attractive foliage. Each leaf is rather thick to feel, oval in shape, relatively smooth to touch and shiny in appearance. 

The attractive, globe-shaped fruit of the perfume flower tree.

The perfume flower tree is said to be a plant that can be grown in large containers. It has average water needs and hence its roots should be kept moist and not allowed to dry out. Like most other flowering shrubs, to ensure that a perfume flower tree plant grows healthily and blooms, each specimen should be grown in an area with at least filtered sunshine (semi-shade), althought it can tolerate full, direct sunshine outdoors. In a high-rise apartment, one can try growing it in a location with direct sunshine for at least 4 hours daily.

‘Yin Yang’ Flower spotted on a Firecracker Plant!

The firecracker plant is a highly branched shrub that is commonly grown in planter boxes where the plant is allowed to cascade over. It produces numerous wiry stems with no obvious structures that look like leaves. As the branches emerge, they first stand up erect and as they grow longer they cascade downwards due to their weight. The fine foliage that spills over the edge of the planter box has an added advantage - it helps to ‘soften’ the harsh and sterile look of the hardscape.

The ‘Yin Yang’ Flower produced by a firecracker plant grown in HortPark.

This attractive, ornamental plant is botanically known as Russelia equisetiformis and is a member of the Scrophulariaceae family. It produces numerous small, tube-like flowers that look like firecrackers from afar. They are usually red in colour although there is another variety that produces white flowers.

Recently, Mr Keneric Ng, a Plant Information Officer from the Plant Information Unit of the National Parks Board (NParks) reported a case where a firecracker plant was found to produce an interesting-looking, bicoloured flower that was coloured two-fifths in red and the remaining three-fifths in cream.

See how cleanly the two colours were split in a single flower!

I was quite amazed and impressed with this report as Keneric must have really sharp and observant eyes to be able to spot such a minute phenomenon! I would have missed this single unique flower among the numerous flowers that a firecracker plant produce at any one time. Such a flower can be difficult to see as it could potentially be buried inside the heap of fine foliage of the firecracker plant!

The cultivar of the firecracker plant grown in HortPark that produced this one of a kind type of flower is known as ‘Flava’ which is characterised by its slightly yellow-looking foliage. The plant usually produces red coloured flowers and the ‘Yin Yang’ flower that it produced recently could have been an isolated and once-off case as mentioned by Keneric in his report.

HortPark’s Mistletoe

Many thanks to NParks, I am given yet another interesting piece of information about a plant growing in HortPark to share with anyone who comes across my garden blog. This time, it is about a mistletoe plant that was flowering in HortPark’s Irrigation Pond.

Mistletoes are plants that are not welcomed in most people’s gardens. They are hemi-parasitic plants which grow on the branches of woody plants such as a tree or shrub. Hemi-parasitic plants are those that contain chlorophyll, capable of making their own food and do not totally rely on the host plant for food. 

A mistletoe plant attaches itself into a plant via a structure known as a haustorium and from there, it leeches nutrients from its host to supplement what is produced from its own photosynthetic process. The vigour of plants that have mistletoes growing on them may be reduced and they can be killed if there is a heavy infestation. 

The mistletoe plant that was in flower in HortPark was identified to be Dendrophthoe pentandra and is a member of Loranthaceae family. The plant that caught the attention from the staff at HortPark was a big, low-hanging clump that was attached to a Terminalia catappa (Ketapang). This particular clump was specifically instructed to be left undisturbed on the branch for study and observation. Most people would have removed mistletoes upon seeing them at first sight.

Although mistletoes are pests, they have an important role to play in the garden. Dendrophthoe pentandra is known to be a butterfly host plant to the Painted Jezebel (Delias hyparete metarete), which is a beautiful butterfly with bright yellow and orange colours on its wings. The larvae of this butterfly feed on the leaves of this mistletoe and a plant can become totally defoliated if there is a large number of caterpillars. A whole clump of mistletoe can be killed this way and perhaps this is how the population of mistletoes is controlled in Nature. More information about the Painted Jezebel’s life cycle can be viewed via this link.

Our ‘National Shrub’ – Syzygium campanulatum in Flower

Nowadays, Syzygium campanulatum is so pervasive in Singapore’s landscape that it can be labelled as the ‘National shrub’ of Singapore. This plant is most frequently seen being grown as a hedge and there are occasions where I have seen plants that have been sculptured into nice topiaries. When left alone, Syzygium campanulatum can actually grow into a tree. 

A first reason why S. campanulatum is a popular candidate for hedges and topiary is probably due to its adaptability towards hard pruning. The next reason would be that after each round of hair-cut, the response put forth by the plant is the production of visually appealling, brightly coloured young leaves.

The red-leaved form of S. campanulatum is on the left while the orange-leaved form is on the right.

This makes S. campanulatum a prettier alternative candidate for landscaping than the all green Baphia nitida that used to be the popular hedging plant in Singapore. In the past, B. nitida was most often seen to being used as a hedging plant to disguise the neighbourhood bin center (a centralised rubbish disposal site). Besides the lack of interesting foliage colours, another reason why people avoided using B. nitida now is probably due to this unglamorous use that conferred the plant a bad reputation as a ‘rubbish bin plant’.

The most common form of S. campanulatum we see in Singapore is the one that produces orange young leaves. Recently, a new cultivar that produces intensely red leaves has made its debut in the local landscaping scene. All this mention about the colourful leaves of this shrub would seem to make S. campanulatum more like a foliage plant, but do people know that S. campanulatum does actually flower?

A single red-leaved form of S. campanulatum grown as a tree in HortPark.

Recently, the rather erratic local weather conditions seemed to have induced many plants to flower. The red-leaved form of S. campanulatum in HortPark was reported to be one of them. The flowers of S. campanulatum are borne in a cluster. Each flower appears like a powderpuff due to the numerous stamens, a characteristic found in the members of the Myrtle, Myrtaceae family of plants. The usual orange-leaved form of S. campanulatum are creamy-white while those of the red-leaved form are maroon in colour! 

A closer look at the crimson powderpuff flowers of the red-leaved S. campanulatum. 

As mentioned by the staff at HortPark, besides the uncontrollable weather stimulus, another important factor that decides whether S. campanulatum will flower or not is how extensively one prunes his plants. This factor, unlike the weather, is controllable and unnecessary pruning is not recommended if one wants to see his S. campanulatum in flower in the ‘season’ that is suitable for flowering. We often do not see S. campanulatum that are used as hedges and topiaries in flower because the plant is frequently pruned to shape.

The next time round when one visits HortPark, do drop by display plots no. 22 & 23 and the Fantasy Garden to take a look and appreciate the attractive foliage of the red-leaved S. campanulatum. If one is lucky to visit during the plant’s blooming season, the shrubs there may be flaunting their flowers.

Many thanks to NParks, particularly HortPark, for sharing this piece of information about the blooming of  S. campanulatum in HortPark as well as granting me the permission to reproduce the text and pictures in this blog post.

Bauhinia galpinii in Bloom in HortPark!

Another floral show has began in HortPark. I have been informed by Cheow Kheng from the National Parks Board (NParks) that several Bauhinia galpinii plants planted in HortPark’s Car Park Garden are flowering now. First and foremost, many thanks to NParks for giving me the permission to reproduce their pictures of Bauhinia galpinii on this blog post.

Commonly known as “Pride of the Cape”, B. galpinii is native to South Africa and is a relatively drought-resistant and undemanding plant. Like many ornamental Bauhinia species grown locally, it is a woody, scandent shrub that requires some form of support to grow on. It is a very versatile plant that can be trained onto a strong trellis or grow over a pergola.

Bauhinia galpinii is relatively free flowering under Singapore’s climate and hence one can expect to enjoy the beautiful flowers almost all year round. Like many other Bauhinia species, B. galpinii needs to be grown in a well-drained location where it can receive as much direct sunshine as possible. It is only for outdoor gardens due to the size of the plant as well as its great need for direct sunshine. 

Remember to place mulch on the plant’s root zone as bauhinas usually like their feet cool and moist at all times. Try not to prune plants too often as they produce flower buds on new growth.

Rare Bauhinia IDed!

A rare Bauhinia species in HortPark is in flower recently. With the help from the Singapore Botanic Gardens’ herbarium, the plant has been identified to be Bauhinia bracteata (Benth.) Baker subsp. bracteata. It is a Bauhinia species that is native to the Indochina region.

Most of the Baunhinia plants we see here are grown as ornamental trees and shrubs and may produce red, orange, yellow or white flowers. The flowers of Bauhinia bracteata (Benth.) Baker subsp. bracteata are greenish yellow and have a spidery appearance.

Its butterfly-shaped leaves are highly ornamental as well. The newly emerged, young leaves take on a red or orange tone which gradually turn green as they mature.

This flowering Baunhinia is located at Display Plot 26 at HortPark (33, Hyderabad Road, Singapore 119578). Many thanks to Cheow Kheng and the National Parks Board (NParks) for sharing this interesting piece of information and kind permission to reproduce the photographs on this blog.

Moonflowers at HortPark

For those of you who have paid a visit to HortPark recently, you may have spotted some beautiful moonflower vines growing on the wall of one of the Gardens by the Bay’s experimental glasshouses that are located at the rear of the park.

Large clusters of lush foliage featuring heart-shaped leaves hang down from the wire supports and what stood out against the green were the large, white, trumpet-shaped flowers of the moonflower. What a sight! The look of the area where the moonflowers were growing gave me an impression as if I seeing this floral display in a temperate country.

It was not too late in the evening and the sky was still bright. I reckoned the time was about 6 pm when I took the photograh but the moonflowers were already fully opened.

Below the moonflower vines, groundcover plants with a prostrating habit were grown to mask the ugly soil surface. The numerous, dainty and colourful flowers that these groundcover plants produce helped to create a vivid parade of colours that was visually pleasing in the day when the moon vines were not in flower. Some of the plants that were used for this important purpose include the Busy Lizzie (Impatiens spp.) which are close relatives of the common Balsam Plant, as well as, the common lantana plant (Lantana camara).

To create a similar spectacle in your garden, it is essential that the location where you want to create it receives direct sunshine for a large part of the day. Many of these flowering vines and shrubs need strong sunshine to grow and flower well.

Soil has to be well-draining and fertile. Do make it a point to water frequently, as many of these plants are very thirsty individuals. They should never be allowed to dry out!

Space the moonflower vines apart adequately and do prune the vines back a bit occasionally so as to allow light to shine through and down to the groundcover plants below. If the groundcover plants are shaded excessively, they will develop an ugly, straggly growth habit and flowering will be inhibited.
