How to notice Siam Majestic (Black RCN) and Black Giant

Hi Adenium Friends;

Today I would like to explain how to differentiate between Arabicum: "Black Giant" and Arabicum: "Siam Majestic" (SM or Black RCN). As I told you last time, we know that Black Giant was originated from Yak Lop Bu Ri or we can call "Black Lop Bu Ri". The owner of this Mother Plant is Liutenant Piya. He is my really closed friend. I will show you his photo soon. The Siam Majestic is mixed hybrid between RCN and BG.


Mr. Piya and his Yak Lop Bu Ri and also he was the
owner of Black Giant Mother Plant - The grand
champion 1998 Contest at Lop Bu Ri Province.
He is my best friend.


The easy thing to notice the difference is the internodes around branches. BG consists of many internodes and clearer than SM. BG caudex color is like dark brown. SM skin color is pretty red brown.



SM leave is shiny, some can have red middle line bone. It's also thicker than normal RCN. Some might have a little bit hairy coz of more BG mixing up.

How to make Dwarfs? Part II

Hi Arabicum Lovers; Today I would like to suggest more how to make Dwarf Form and Contest Form. Actually developing the Dwarf Form, the most important thing is to notice the mother plant form. For example, if you have tall mother plant, it's hard for you to get seedling as Dwarf Form. In the opposite side, if your mother plant is like tower style so it's pretty hard to maintain as Dwarf Form.

minerals, rock, water, air, organic matter (plant and animal residue), microorganisms, including bacteria, fungi and protozoa and a variety of insects and worms. In healthy soil this intricate web carries out a process that continually replenishes the soil and maintains long-term soil fertility. I use the fermented soil (with EM and Molass) mixed with cow manure and rice husk. Normally I ferment soild for 3 months before using. This soil is mostly lack of Minerals necessary for the plants. Most people think only fertilizer (Main N, P, and K) is enough, but exactly not. We also need more mineral to be another factor build up more root and expand caudex.

For sustained growth plants require 16-17 elements generally referred to as macro-nutrients and trace elements. Macro-nutrients include, nitrogen (N), phosphorous (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S). Trace elements include, iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn). For optimum plant growth, the soil must be capable of storing these nutrients and transferring them to the root surface for uptake by plants.

For Fertilizer use, I recommend to use Natural Organic Microorganics with Minerals instead of normal fertilizer with main N, P, and K. This fertilizer give benefit to special fungi name "Mycorrhizal". Normal fungi help decompose the organic matter in litter and soil but play less of an overall role.
Mycorrhizal fungi help develop healthy root systems by growing on plant roots. The fungus is actually a network of filaments that grow in and around the plant root cells, forming a mass that extends considerably beyond the plant’s root system. This essentially extends the plant’s reach to water and
nutrients, allowing it to utilize more of the soil’s resources. Best caudex development also needs the full sun and enough watering are the keys to this. ok, if you have more questions, please email me. Thanks friends..

How to categorize PNW based on Forms?

Hi Arabicum Lovers,Arabicum-Petch Na Wang (PNW) is one of my favorite Arabicum. I mostly use this hybrid to be maintained as Dwarf or Contest Form. From my experiences, I can categorize PNW into 5 popular styles. Please see below..

1. PNW-Multi Branches : This is very attractive style mixed with RCN blood. Leaves are almost shiny and some can have a little bit hairy. There are many internodes on the top branches. Branches are not big but too many.

2. PNW-Peacock Style : Almost the same as item 1. but more branches spread parallel to the ground. This form is pretty hard to find and I really love it.
3. PNW Muscular Style : Branches are not too many like item 1 and 2 but they are kind of big. Internodes are also less than item 1 and 2. Caudex is also big and great for Dwarf Form. Mostly I like to use this form to join in the contest. I called this form as "Muscular".
4. PNW White Ivory: Almost the same as item 3 but skin is white. Internodes are distant and not too many. Caudex skin is wrinkle like elephant skin so I called her as "White Elephant".
5. PNW Flamable Style : This style is also consist of RCN blood. Many branches are spread into the top. Internodes are not too many. Leaves are pretty shiny like RCN.

Next time, I will show you another great PNW mixed with Petch Muang Kong. Have a nice day.

The difference of Black Knight and Black Giant

Hi Arabicum Fans;

I have many questions about what difference between "Black Knight" (BK) and "Black Giant" (BG) so I will explain you following with their characters. Black Giant is the first generation of Black Arabicum here and Black Knight (Named by us) is the second generation.

You can find out more about Black Knight from "The Legend of Siam Black Knight" as below. I seperate the difference for each categorized by flower, leaves, caudex, seed pod, and seed.

1. Flowers
BK: Flower is softer pink, one tone petal and special with red stripe in the yellow throat.

BG: Flower is darker pink to almost red. Flower's petal background is pink and also has deep pink border around.


2. Leaves

BK: Leaves are fresh green, long, wider, thicker, hairy and some might have the red middle line.

BG: Leaves are smaller and curve at the end. Leave line is very clear with red middle line or bone. Leave color is soft green.



3. Caudex

BK: Caudex skin is almost black from top branch to caudex base.

BG: Caudex skin is brown or some can be black all caudex as well.

4. Branch

BK: Branch is more black and consist of few internodes.

BG: Branch is black and consists of many distinctive internodes.

5. Seedpod

BK: Bigger and close together.

BG: Smaller and more distant like V-Shape

6. Seed

BK: Seed is longer and bigger size and also the biggest size compared with other Arabicum seeds.

BG: Seed is smaller and round like rugby ball. Some seeds can have hairy at skin.

The Black Giant was developed from Yak Lop Bu Ri. The owner of Lop Bu Ri's Mother plant is Luetenant Piya and he is the one who named this hybrid. He is my close friend and we have studied and worked together on this hybrid for 3 years. He told me that his uncle recieved 2 youngseedlings about 15 years ago from Saudi Arabia. Both of them were grown for 1 years and Mr Piya noticed that one of them got black skin on top branches so he gave this plant as a name of "Yak Dam" as Thai people called til now.

The English name "Yak Dam" is "Black Giant" and use as marketing term. "Yak" means "Giant" and "Dam" means "Black".

Mr Piya simply said "Black Giant" is just Yak Lop Bu Ri which just has black branch skin. Some Yak Bu Ri can have brack branch almost same as Black Giant (Please see the left photo). You can notice all branches are almost the same as Black Giant but flowers are like Yak Lop Bu Ri. I think this could be clear what difference between Black Giant and Black Knight.

The Legend of real Master of Black Knight

Hi Arabicum Lover;

I have got many questions about the Legend of Black Knight. Today I would like to tell you the story. The Black Knight motherplant was grown from villager at Korat city 20 years ago. After that she has been taken by the owner nursery there. Two years later she got severely rotten at caudex so that owner of nursery was afraid of her dying then he cut her into 3 big branches. One year later, he closed his nursery and sold all plants including 2 Black Knight' branches, one of them was rotten and died with him, to two guys. One branch was sold to Mr. Tawee, owner of nusery located at Nakorn-Sawan city. Another one was sold to somebodyelse and he forgot who sold to.

Three years later, I was so lucky that I have a chance to meet Mr. Tawee and bought this mother plant which he also guarranteed that this was the 1st generation of Black Knight (or Mother Plant). I am Arabicum lover and really like develop the Arabicum hybrid from real blood Mother Plant.

I also got many questions what difference between Black Giant and Black Knight. Many years ago, we called Black Knight as same as Black Giant as well. After I found her and see she got many differences with Black Giant such as form, flowers, leaves, seeds, caudex and seedpods so I gave her a name as "SIAM BLACK KNIGHT".


You can easily notice the real Black Knight from her flowers and leaves. Her flowers are softer pink and only one tone, no pink petal border. Leaves are longer and more hairy on both sides.

New Thai Socotranum: Petch Ban Na (Tower Style)

Hi Thai Socotranum Lovers:

Today I would like to talk about Thai Socotranum: Petch Ban Na (PBN). PBN is one of our popular Thai Socotranum. This PBN is very unique unlike other Thaisocotranums. The easy part you can see is that flower because her flower is the most soft pink compared with other Thai Socotranums.

As of today, we have developed our new style of PBN seedlings which all of them are grown from seeds harvested from the 1st original mother plant. We are pretty believe and trust in TRUE hybrid especially with Thai Socotranum. The reason is that Thai Socotranum is very slow growing and the best form will represent at least 1-2 years so we would not like to waste our time, wouldn't we?

Here are some of our seedlings with NEW tower style and have shubby on the top of branches surrounded with side branches. We have tried to develop form like real Socotranum from Socotra Island. We totally guarranteed that all of them are 100% TRUE seedlings almost the same as Mother Plant so you will be happy and sure that you get the TRUE ones. Now 1st seedling lot is released now!
