5 Flowering Trees in Bloom within the Neighborhood

There are 5 tree species which are currently in bloom in many parts of the country. The blooming season coincide with the intense heat of the dry season, which is common in western parts of the country and in Metro Manila.

While walking within the immediate vicinity, i was able to take photos of some trees in bloom.

5 Trees in Blooming Season

5.) Narra scientifically called ( Pterocarpus indicus) apalit,asana, agsana padauk, mukwa, Burmese rosewood, Andaman redwood, Philippine mahogany.

This tree species is found over wide range in Asia from India, Sri Lanka, Indo-China, Indonesia, Singapore, Papua New Guinea, Ryukyu islands, Solomon islands and the Philippines.

IMAGE

This tree species was declared the national tree of the Philippines in 1934 by Governor Frank Murphy. The blooming season of this tree species is between late February to early June.

It is quite hard to find old narra trees suitable for furniture and wooden floors. It is also expensive. People should plant more narra trees, since they are slow grower.

4.) Banaba – scientifically called ( Lagerstroemia speciosa (L.) Pers.) This flowering tree is locally called banaba, bugarom, bugarum, duguam, mitla, nabulong, pride of India, Queen’s flower among others. The tree grows between 5 to 20 meters in height.

Found in wide range of location from India, Bangladesh, Indo-China, Malaya, Taiwan, southern Japan and Philippines.

The young leaves are used as purugative and sometimes used in making local tea. Older tree can be used for timber.

3.) Royal Poinciana ( Delonix regia) – locally called flame tree, fire tree, flamboyant tree, peacock tree, caballero. The tree was introduced to the country via Mexico from Madagascar probably in the late 17th up to the early part of the 19th century. It is now considered common, pan-tropical and found in many parts of the globe. This had different blooming season in various countries where it was introduced.  The blooming season is from early March to mid-June in the Philippines. Urban myths and local folklore that flowering signals the imminent arrival of the monsoon season.

Plaza Roma and Manila Cathedral Basilica days before the enhanced community quarantine

Old photos in the 19th century showed flame tree planted in Plaza Mayor in present day Plaza Roma in front of the Manila Cathedral. In 2008, former Intramuros administrator Ms. Anna Marie “Bambi”  Harper gave permission the cutting of 29 narra, mahogany, ficus trees within Plaza Roma and then replanted some flame trees within the plaza. As reported by ABS-CBN channel 2.

This sparked some outrage in local plant conservation societies, since the tree is non-indigenous/ native. Its shallow root system is prone to toppling off during heavy rains or during typhoon.

2.) Acacia( Samanea saman/Albizia saman ( Jacq) F. Muell) known locally as acacia, akasya, monkey pod tree, cow tamarind, rain tree, false power puff tree which originated from tropical America. In Indonesia it is called meh, trembesi. it is called pukul lima, pokok hujan (“rain tree”), ampil barang in Malaysia.

Acacia/ Akasya found its way to the country during the late 16th to early part of the 19th century via famed Manila-Acapulco galleon trade.  The tree species can grow between 30 to 60 meters in height and can be spectacular sight.

Now, this tree is found in many parts of the world and is considered pan-tropical.  It is  is widely planted as shade trees in parks, boulevards, churches, plazas, cemeteries and large estates.

The wood is beautiful is used in wood craft, cutting board and in planting denuded forest areas.

There are also many folkloric tales, urban legends which surround old acacia trees throughout its pan-tropical and sub-tropical range.

There were several centuries-old acacia trees found in many parts of the country. Paco Park boast of several trees which had witness the death of Dr. Jose Rizal and burial of prominent personalities within the park. Saint Anne Church in Taguig also a mute witness to the Philippine revolution, second world war and new millennium.

Far Eastern University’s in Manila campus also boast of an acacia tree which was planted and nurtured by the founder Dr. Nicanor Reyes Sr.

While the University of the Philippines Los Baños campus boasted of century-old fertility tree. I had a privilege to join a heritage tree walk in 2012 conduced by the Late Dr. Roberto E. Coronel  when he was still alive.

The sad part was i also seen the dying acacia tree along Padre Faura street and a well-known fast food restaurant nearby.

Acacia tree is also host to different eipiphtyes such as ferns, orchids and hoyas in Nagcarlan, Laguna province.

Older tree can host several species of epiphtyes like Drynaria quercifolia, Asplenium nidus, hoya, Dendrobium crumenatum ( dove orchid), Luisia teretifolia ( bee or fly orchid )among others.

seed pods are also used as maracas by some musicians

1.) Golden Shower Tree- ( Cassia fistula) This is called under many names such as April shower tree, golden shower, purging cassia, Indian laburnum, pudding-pipe, kanya pistula, amaltaas, lapad-lapad, bistula, ibabau, lombayong or Royal Ratchaphruek tree in Thailand.

I have written an article about the folkloric uses, urban legend which surround the blooming cycle of this flowering tree species in the country.

IMAGE

Local botanists and horticulturists agree that the flowering tree was introduced into the country long before the arrival of the Spaniards. Might have been brought by sea traders from other southeast Asian countries like Vietnam, Thailand or Indian traders.

Common Names and Range

Cassia fistula is commonly known as Golden shower, Golden Rain, April Shower, Yellow Shower, Pudding pipe tree,Indian Laburnum, Kanya pistula, Caña Pistula, Pistula ( Tagalog speaking provinces) Bistula ( some parts of Sorsogon and Visayan provinces) , Ibabau ( Visayan) among others. This flowering tree was probably introduced into the country at an early date, probably by traders or immigrants from Southeast Asia which may have brought the seeds of this tree during the pre-hispanic times.

Cassia fistula was featured in the Flora de Filipinas book by Father Blanco. The flowering tree seems to be wide spread in many places that some local botanists would argue that it can be an indigenous species to the country. The flowers are normally pollinated by carpenter bees and even sun birds.

The species is native from Pakistan, Indian subcontinent and within southeast Asia.  Golden shower tree is a flowering plant in the family Fabaceae.

Cassia fistula is called Ratchaphruek in Thailand

Cassia fistula is called Ratchaphruek by Thais and is  the national tree and flower of Thailand. It is also the state flower of Kerala in India and of immense importance among the country’s Malayali population. This popular ornamental plant is also used in herbal medicine. The tree is also used in the production of paper and source of wood.

The flower was also featured in Thai, Laos, Canada and Indian postage stamps.

Folkloric Uses and Superstitious Beliefs

This tree is widely planted in many private subdivisions, community parks, Rizal park, intramuros, avenues, streets and cemeteries in many parts of the country.

This serves as focal point in many landscape projects, street side and boulevards. Some people believes that it attracts positive energy and wish can be granted once the flowers opened freely. One must make a wish just after the stroke of midnight  during full moon. One must gather few flowers and keep them on a tissue paper or handkerchief for keepsake.

In Laos, The flower are called Dok Khoun– Some people attach the flower on their cars and motorbikes during Lao New Year with the same belief that it will bring them good luck, happiness and safety while driving.  Its yellow colored flowers brings good luck, freshness, remembrance, brings positivity, brings happiness,intellect, clarity, enlightenment, loyalty and joy. They are also planted in front yards of one’s home.

An artist from Rizal province also told me that they use to gather the seed pods and dry them for several weeks. Use them as musical instrument, the sound is like maracas.

Another faith healer would use the seeds and rub them on skin on people that would visit her place. While a soothsayer in Quezon province (manghuhula ) would gather its seed pods and use the pods for fortune telling session. A peculiar ritual for the manghuhula is to gather seed pods during Mahal na Araw ( preferably during Good Friday )and have vesper ( orasyon) or magical incantation so that the seeds would have some potency to protect the owner. The seeds are sewn into a red cloth with markings, this are sometimes used as amulets to ward off evil intention or negative vibes.

Some us the leaves ( after pounding them ) seed pods are used as purgative, and extract from seed pods are used to alleviate constipation. The leaves are pounded and ground into a paste like consistency and are rubbed on ringworm ( an-an) and other fungal diseases.

Another urban story told to us by Mr. Carlos Valeriano Lazaro ( former president of POS and LBOS) state that whenever the April shower flowering season would appear. It means that the rainy season is just few weeks away.

Propagation and Care

Cassia fistula can be propagated by seed and vegetatively through cuttings and air layering.  April shower or Golden Shower trees can grow between 10 meters to 25 meters in height.

The key is collecting the seeds when they are mature but not overripe ( dark brown color). The best time to harvest the seed pod, Are the seed pods produce over last year’s blooming season.

The seeds germinate best when the days are long with extra hours of sunshine. Rinse the seeds in warm water to remove the dark pulp.

One can soak the seed in  water for about 24 hours. Then try to scar the seed by rubbing them on cement or any hard surface in order to scar the seed.

Try to plant each seed in its own gallon pot with drainage holes on the bottom. Fill the pots with lightweight, sterile medium. Sow the seeds 1 to 1.5 inch (2.5 cm to 3 cm) deep, then position the pots in a warm, indirect light condition.
Depending on the temperature condition, one can germinate the seedling between 3 weeks to about a month.
Propagating via seeds can be long process and can take between 3 to 5 years before it start blooming.
One can place the seedling on ground when the seedling reach at least 1 year, this will hasten the growth.

One must not forget to occasionally apply organic (compost) and inorganic fertilizer every two or three weeks interval.

Do not forget that regular pruning of this tree is needed before it get too tall. Enjoy the annual blooming season by having a viewing party or photo session with the tree.

ficus trees lined the street going to the park

The park is home to more than 150 species of trees and flowering plants  plus about two dozen known birds. Every Year there were at least  75,000 to 150,000 people who visit the  their beloved ones who are buried . There is a also a group joggers from different associations.

Spathodea campanulata or African Tulip Tree

This tree species  was probably introduced to the country  from tropical Africa during the American regime. In certain parts of the world, it is known as the Fountain Tree as well as the Flame of the Forest.

This is a popular ornamental tree in the tropics and is much appreciated for its showy reddish-orange or crimson flowers. It can provide ample shade and because of its bright flowers, it’s always a colorful addition to any garden. The wood is difficult to burn, so the tree is also valuable for fire resistant landscaping. It is cultivated in parks, gardens, and along roadsides. It is commonly seen growing around Metro Manila and Tagaytay area and is often considered an evergreen, though it sheds its leaves during summer.

The flower buds form a ball-shaped cluster. Each brown banana-shaped flower bud is filled with water, forming a natural water pistol when squeezed. The outer buds bloom first before the inner ones. The tree blooms year round and a flower lasts about 3 days. The ripe pods split open into a woody, boat-shaped form. Children use them in boat races, by placing the opened pods in a fast flowing drain.

Medicinal Value:

Though there is no reported folkloric use here in the Philippines, Its leaves, root bark, stems, and fruits yield alkaloids, tannin, saponin, steroids, terpenoids, and flavonoid and are used in African medicines. In some African countries, the stem bark is used as a paste for healing wounds as it has anti-microbial properties. In Ghana, the stem bark and leaf are used for treatment of dyspepsia and peptic ulcer; while the leaf, root bark, and fruit is used for arthritis and fractures.

This tree can survive in shaded areas, but it requires full sunlight exposure to be able to grow fast and bloom with an abundance of flowers. It can even grow faster when there is plenty of moisture though it endures droughts by shedding leaves.

Couroupita guianensis or Cannon Ball Tree

Couroupita guianensis, whose common names include Ayahuma or  Cannonball Tree, is an  tree allied to the Brazil nut (Bertholletia excelsa), and is native to tropical northern South America and to the southern Caribbean . In India it has been growing for the past two or three thousand years at least, as attested by textual records; hence it is possible that it is native to India also. It’s part of the family Lecythidaceae and grows up to 25m (82ft) in height.

The “Cannonball Tree” is so called because of its brown cannon-ball-like fruits. The majority of these trees outside their natural environment have been planted as a botanical curiosity, as they grow very large, distinctive flowers. Its flowers are orange, scarlet and pink in color, and form large bunches measuring up to 3m in length. They produce large spherical and woody fruits ranging from 15 to 24cm in diameter, containing up to 200 or 300 seeds a piece.

Introduction:

This introduced species was probably brought to the country during the American regime . Its decorative flowers and fruit makes this tree ideal as a focal point in large gardens and estate. However it is not recommended to plant this tree in small garden spaces .

The tree gets its common name from the large, spherical fruits it produces. The fruit falls from the tree and cracks open when it hits the ground when mature, often causing the sound of a small explosion. The fruit emits an unpleasant aroma when exposed to the air. Individual seeds within the “ball” are coated with hair, which is thought to protect the seed when it is ingested and may also help in the passage of the seed through the intestines.

Traveller’s palm

Ravenala madagascariensis, commonly known as  Traveller’s Palm, is a species of plant from Madagascar. However , horticulturists do not consider this plant as a true palm(family Arecaceae) but a member of the bird-of-paradise family, Strelitziaceae.this plant is the sole member of its genus. This plant was introduced to the country during the early American regime and is widely distributed as a common landscaping plant material.

Chrysalidocarpus  lutescens called palmera / butterfly palm

  Local folk called this palmera because of its fronts and commonly used as an ornamental plant and backdrop for flower arrangements . This is a common palm found in most pan-tropical countries around the world.

A slender , clustering palm that can grow height to more than 12 meters. The graceful yellow green leaves and can reach up to 2 meters. This palm is native to Madagascar and was introduced in the early 20th century in the country as landscaping material. It is now commonly found in parks , private homes and this palm is also popular as indoor potted plant.

Hyophorbe lagenicaulis or bottle palm

Bottle palm was introduced to the country some  20 to 30 years ago via Bangkok, Thailand  and Florida nurseries  , Filipino landscapers usually used this palm to landscape the front lawns  of the houses. The compact growth of this palm is ideal for those who do not have large spaces. There are specimen sized palm planted in some exclusive villages in Forbes Park , Corinthian Garden, Valle Verde, Ayala- Alabang  and in Greenhills .

Chua family mausoleum

Bottle Palm has a large swollen (sometimes bizarrely so) trunk. It is a myth that the trunk is a means by which the palm stores water. Bottle Palm has only four to six leaves open at any time. The flowers of the palm arise from under the crown shaft.

Roystonea regia or Royal Palm

Royal palm was introduced to the country during the late Spanish period and was planted in public places such as in Malecon drive ( aka Bonifacio Drive) , Intramuros , Hardin Botanico de Manila now known as Mehan Garden .

Roystonea is a genus of eleven species  of monoecious palm, native to the Caribbean Islands and the adjacent coasts of  Florida , Central and South America. Commonly known as the royal palms, the genus was named for Roy Stone, an engineer in the US Army . It contains some of the most recognizable and commonly cultivated palms in tropical and subtropical regions.

The flowers are used in Southeast Asia for several purposes. They are primarily used for worship at temples whether at home or out, and more generally worn in hair by girls and women as a means of beauty ornament as well as a natural perfume. Flowers are used to be floated in bowls of water to scent the room, as a fragrant decoration for bridal beds, and for garlands.

Mussaenda philippica variety aurorae

This is a tropical shrub or sub-shrub that will grow to 10ft tall in tropical areas, but more likely will reach 1-3ft tall in containers. Clusters (corymbs) of small, tubular flowers with five spreading lobes bloom in summer, however it is the large and colorful, ovate, leaf-like sepals (to 3” long) that provide the real ornamental display. Some individual flowers in each cluster will develop a single enlarged sepal. Elliptic to ovate, bright green leaves (to 6” long). Hybrids typically feature flowers in red and/or yellow with showy sepals of white, bright red or pink.

Origin: named after Donya Aurora Aragon- Quezon , wife of a former President Manuel Luis Quezon of the Philippines .

White Mussaenda also commonly called  Virgin Tree or Donya Aurora can be grown as ornamental in parks and public gardens or along roadsides, byways and highways. Use in landscaping, this plant serves well as a decorative specimen with its showy blooms and would fit beautifully in home gardens too! Attractive to butterflies, bees,  and insect pollinators as a nectar plant.

The golden form of Golden Vietcha or Adonidia merrillii  golden is widely used as landscaping plant

This is a mutant variety of the, Bunga China , Bunga de Jolo, Manila Palm or Christmas Palm.The palm can reach up to  a height of 15-20 feet. The gently arching fronds are bright green and grow lushly from the top of the crown shaft. They grow to a length of 5 feet with leaflets up to 2 feet long by 2 inches wide.

Two foot long, branched flower stalks emerge from the area where the crownshaft meets the gray trunk. Pale green flower buds open into spidery cream-colored blossoms.

Tale of Discovery:

One mutant palm that has made a lot of growers much richer is the so-called Golden Veitchia. This is a golden mutation of the ordinary Bunga China or Veitchia merrillii. This was first discovered in the garden of Mr. Cesar Pecson in Singalong, Manila, in the mid-1980s. It came from the fruits of a Bunga China planted beside the gate of Pecson’s home.

According to Mr. Zacarias  Sarian , While having snack  in Pecson’s garden,  Mr. Sarian  saw some of the seedlings that sprouted from the fallen fruits on the ground had golden leaves. He suggested to Pecson that he pot those golden seedlings and then sell them at the Baclaran plant market where he had a stall. That’s exactly what he did and was glad to sell them at only P25 per seedling. When he observed that people were buying his seedlings, Pecson raised his price. He raised all the more when the plant traders from Bangkok learned about the Golden Veitchia and bought everything that was available.

Somehow traders from Bangkok and Malaysia were able to buy some seedlings of the mutant variety which they re-package the name Golden Butia or Golden Vietcha !

Many of the local growers made money by selling some of their full grown plants to landscapers at a high price. Some of the plants they retained bore fruit and they also produced Golden Veitchia seedlings which they were able to sell at a good price.

In Thailand, the Nong Nooch Garden Resort is now growing Golden Veitchia by the hectares and is selling them at a high price. The price of the mutant variety sky rocketed and even reach a several thousand of pesos !This has made not a few growers not just a little richer.

Since the Thai’s were very good in cultivating the mutant strain , they were able to successfully marketed in mass quantities  in just matter of years .

Now, the price of the mutant variety is more affordable but still more expensive then the ordinary form.

                                       Bread Fruit/ Kamansi/ Rimas (Tagalog ) Kolo

Breadfruit (Artocarpus altilis) is a species of  the mulberry family, Moraceae  growing throughout Southeast Asia and most Pacific Ocean islands. Its name is derived from the texture of the cooked fruit, which has a potato-like flavor, similar to fresh-baked bread.

The ancestors of the Polynesians found the trees growing in the northwest New Guinea area around 3500 years ago. They gave up the rice cultivation they had brought with them from ancient Taiwan, and raised breadfruit wherever they went in the Pacific (except Easter Island and New Zealand, which were too cold). Their ancient eastern Indonesian cousins spread the plant west and north through insular and coastal Southeast Asia. It has, in historic times, also been widely planted in tropical regions elsewhere.

                                                                                         Banaba tree in bloom

Lagerstroemia speciosa  is a  decidious tropical flowering tree, 5 to 10 m high, sometimes growing to a height of 20 meters. Leaves, large, spatulate, oblong to elliptic-ovate, 2-4 inches in width, 5-8 inches in length; shedding its leaves the first months of the year. Before shedding, the leaves are bright orange or red during which time it is thought to contain higher levels of corosolic acid). Flowers are racemes, pink to lavender; flowering from March to June. After flowering, the tree bears large clumps of oval nut like fruits.

Author’s note: Most of the trees and plants that the author featured in the horticulture walk blooms on a seasonal basis. It is wise to plan  the tour in order to see what is flowering for a particular month.
