GROWING LARGE-LEAVED TREES FOR BONSAI

GROWING LARGE-LEAVED TREES FOR BONSAI

 Many bonsai hobbyist generally opt to use varieties of trees with smaller leaves for bonsai. In my study however of the bonsai art I find no limitation or constraint as to the use of particular tree varieties.  As a shift to the generally accepted norms in the field of bonsai art, I tried to grow trees with large leaves as bonsai. I found it very interesting and fulfilling.


The following varieties are part of my collections:




Balubituon also called Botong
Butonica Rumphiana Miers

I grow these trees from the seeds I found on the coastal shores of San Francisco, Surigao del Norte, Philippines. The fruit is a little more than my fist size. These specimens have since grown on pots changed from time to time. These were never planted on natural ground. These trees naturally grow to a height of about 8 to 15 meters. Leaves are large, thick and shiny and measures about 20-40 centimeters. Despite growing in a small and shallow pot, its leaves are still large. I have tried to reduce the size of its leaves through regeneration pruning, but not much change is observed. They grow new leaves simultaneously. These are good for home and office decoration.



Octopus Tree or Schefflera
Schefflera Actinophylla

This specimen is a variety of Schefflera Actinophylla which is an evergreen tree with compound medium green leaves. It can grow up to a height of 15 meters when planted on natural ground. It produces long and easily multiplying aerial roots, especially during rainy days. Stalks of compound leaves are easily detached from the main stem.  Each time it buds it also produce new aerial roots. When guided down to the soil these aerial roots can grow and become beautiful part of the bonsai art. These specimens were grown from cuttings.




Bitaug Tree
Calophyllum Inophyllum

This variety is growing abundantly in the coasts of Surigao del Norte, Philippines. This specimen was grown from a seedling I collected from the rock-strewn shorelines of San Francisco, Surigao del Norte. This is a medium to large size tree with medium to large size of thick elliptical glossy leaves when grown naturally. It thrives even in stony shorelines. Its leaves and fruits are said to be poisonous. It is believed that the calophyllum oil produced from its seeds is of medicinal use.




Indian Rubber Tree
Ficus Elastica Gold – Moraceae

The original specimen of the variegated variety of ficus elastica was acquired from a plant dealer. These specimens were taken from my own cuttings from the original. This is a large tree with strangling aerial roots. It is generally found planted in parks because of the shade provided by its long and leaves-satiated cascading branches. Leaves are large and thick with yellow patterns. This is said to have been introduced in the Philippines during the American period.
  

Moreton Bay Fig
Ficus Macrophylla

The original specimen of this ficus variety was found as an epiphyte on a dead coral stone in the shoreline of San Francisco, Surigao del Norte. It was already given as a gift to the friend of my daughter. This is one of the remaining specimens grown as raft style bonsai from cuttings of the original bonsai tree. This ficus variety is said to be common in New Zealand and Australia, I have not yet seen a large tree of this variety growing on natural ground. The original plant must have been from the waste of a frugivorous bird. I observed that its leaves are not easily susceptible to natural enemies.

Hauili Tree
Ficus Septica – Moraceae

It is also known as Tabog tree in many Visayan provinces in the Philippines. It is a small tree which grows from 6-8 meters in height. The leaves are smooth and shiny with pointed tip. It bears fruit the whole year round and a good feeder for frugivorous birds. It is a very common site even in residential areas and subdivisions. This is probably because of its ability to bear fruit that most birds carry its tiny seeds to different parts of the community. Some of its rotten fruits are also eaten by ants and their seeds are carried in crevices of concrete canals and hollow block fences where its roots dig deep into the natural soil. When pruned it produces fast new shoots and branches. It is said to be a natural source of many medical uses and benefits.




All of these specimens were trained for already more than ten years.  Most of them are grown in 8” x 9” x 2” concrete pots, others in 9" x 12" x 1.5" and wider pots of the same thickness and some on more shallow home-made concrete pots. These specimens will look more wonderful when planted in commercial bonsai containers. Above pictures where taken on my bonsai working areas.

PLANT EVOLUTION - MY LITTLE PINE TREE WHICH GROWS A CYPRESS BRANCH

PLANT EVOLUTION - MY LITTLE PINE TREE WHICH GROWS A CYPRESS BRANCH





 Although I do not have a large space in our backyard, I love plants and gardening. I do not have any educational background about plants and trees but I glory in my daily encounters with my plants crowding in our backyard. I am a bonsai hobbyist of about 19 years and have since maintained more than a hundred bonsai art specimens mostly of the Ficus varieties. I started to love doing it as an antidote of the stresses that came about by the pressures of a banking career. My trees are not as good looking as many of those on display because of limited space and very crowded environment. Yet my bonsai trees have stayed strong and alive for years.

About ten years ago, I bought a tiny pine tree from a plant dealer. I already have one larger specimen of the same pine variety. I placed this new specimen in a shallow bonsai pot, but I noticed that it never improved. Fearing that it might die, I planted it in a small but deeper rubber pot. Still I found that it has not developed according to my expectations. So I placed it together with other seemingly failed specimens.

More than a year ago, I noticed that a new bud of different variety grew in one of its small branches. I noted that its leaves correspond to that of a cypress tree. I know and understand that they are of the same family of conifers or pines but I never expected that an ordinary Philippine pine will have produced a cypress branch. It is even more surprising because I do not have any Cypress tree specimens in my bonsai collections. There are large and tall pines growing in front of our home but are of different variety either.  I thought that this must have been an actual evolution phenomenon.




















The many bonsai specimens I have at home are of different varieties of ficus. They are in rows very close from each other, but never did I observe even one of them producing a branch of another ficus variety.

I searched from Google – Wikipedia and I found that “Evolution is the change in the inherited characteristics of biological populations over successive generations.”  For plant evolution I found this meaning; “Plant evolution is an aspect of the study of biological evolution, involving predominantly evolution of plants suited to live on land, greening of various land masses by the filling of their niches with land plants, and diversification of group of land plants.”

I learned though that plants and trees usually evolve through seeds. I did not find any literature about a branch of a different variety evolving or growing from another variety of a mother tree. Modern agriculture introduced grafting to grow a branch by uniting a shoot into a growing plant by insertion or close contact. Usually this grafted bud is of the same plant family even if of different variety.

Most recently I found that a new bud grows on the cypress branch but is again of the mother tree variety.


I really find this phenomenon interesting for I have observed it only once in my whole life. I would truly appreciate if biologists, horticulturists, foresters, bonsai hobbyist and other plant and agricultural experts could explain this occurrence.
