Simple Step to make Dwarf Arabicum
Charateristic that need to pay attention from the Dwarf form or Bonsai Arabicum are :
#1. Skin of the rod looks very wrinkle, more dark color and has many joints.
The dark skin is as sign to stop growing especially in main branch otherwise the caudex will be more chubby.
#2. Remain stable with more short branches in the chubby caudex. Therefore looks like classic and old.
The two character above can be a measurement of quality from Dwarf Arabicum form.
Menahile there are 3 genus of hybrid arabicum that could produce Dwarf Arabicum with good quality i.e Petch Na Wang, Lop Bu Ri dan Sing Bu Ri.
Step to make Dwarf :
#1
Choose the frees and healthy form the above genus.
#2
Use media that can provide drain and watering that can be good germinate of the seed and grow faster.
#3
After the seed become germination follow the growth of the seedling untul 6 month.
#4
The crown with chubby caudex is the best form and make sure the branch skin all is green.
The green branches could be growth bigger.
After 6 months the Dwarf form will be more stable. And then decide whether the caudex will be growth big or to be bonsai.

Make an artistic root for your Adenium
Basically adenium is plant that easy to be customized, particularly with the root. Below are the tips to make your adenium plant perform an artistic plant.
1. Select the plant with minimum caudex size 10 cm.
2. Release the plant from the pot, then spray the root and the caudex with water cleanly.
3. Wipe the root with liquid fungicide, and let them dry.
4. Cut the caudexes into 2 parts on the center with sterile knife.
5. Wipe liquid fungicide to the bottom of the caudexes, and let them dry for 3-4 days.
6. Use stereo form, and cut the stereo form fit to the form of the bottom of the caudexes.
7. Stick tightly the stereo form to the bottom of the caudexes.
8. Plant the adenium to the pot.
9. Wait 3 – 4 month, and you will find your adenium create the root with artistic form.
Happy trying …….

Adenium Seed
Adenium seed can be produced from natural-pollination or hand-pollination. Generally the best hybrid adenium come from hand-pollination.
The seed as result of natural-pollination can not be controlled to get a good next generation. This seed generally only be used for trunk-material due to the form of caudexes can be made an artistic plants.
Most of us know that adenium plant is “a desert plant” that is why called as “desert rose”. The major factors to get sustain generation in desert area is the wind. Adenium seed has hair, slight-skin and hollow-space, therefore easy blown by the wind. When the seed is ripe, then the seed pod will be broke and spread the seed. A couple of seed pod usually produces 100 to 150 of seed and takes 80 days to be ripe.
Adenium seed will be dormant until they find a suitable place to grow, they will react against water. The penetration of the water to the seed will cause the embryo produce a hormone. This process also creates enzyme which will stop dormancy of the seed.
After pass dormant period, the seed start to live through respiration and transform food-reserves become energy. The energy will trigger a sustain process for seed casing separation, create a root, trunk and leaf. The above process kotiledon (part of seed contain food-reserve) will be move-up to the land surface. Kotiledon is used for food-reserve and fotosintetic
Actually adenium is easy to germinate. However there are seed will not want to germinate due to such factor i.e seed fertility; wrong handling seed when harvest, and planting process of the seed.

Watering Adenium
"How much" to water Adenium sounds like easy: to support the plant is growing, always need enough water in the soil thoroughly with some coming out of the bottom of the pot. It may be necessary to water a little each time in the winter, usually with the plant not in growth or even dormant, what we need is just to keep the media from going dry.
The question is How often to water: The factors which will be influence are : 1) season 2) environment, 3) media, 4) fertilizer
Growth: Adeniums can use a lot of water - more than most other plants. Insufficient water will impact the plant will not growth as what we need. But to much water will cause the plant will be rotten.
Environment: hot & dry conditions (sufficient of sunlight), Watering every 7-10 days.
Media: Coco peat + Organic fertilizer + fried hull with Very little water retention.
Container size: Large specimen plants require less frequent water, partly because big pots don't dry quickly and partly because large plants are more resistant to dry conditions.
Growth stage: require frequent watering for young plants, they need growing rapidly. More older of the plant more Less frequent watering.
Growth control: regular fertilizer + nutrients will give a toughened plant with hard caudex. (make a schedule each 2-3 days for fertilizer and nutrients)

Germinating adenium seed
I couldn't remember that when is my first time germinating adenium seed. I just feel that it is very easy and don't even try to remember anything about it. Germinating adenium seed in my growing condition is very easy because I have enough warm and sun all year around. There are 4 things I will mention in this article : seeds, soil mix, temperature and light & humidity.
Seed : This must be the main key to success. Adenium seed loses its viability in short time. Fresh adenium seed can germinate in few days. I have never kept record that adenium seed can hold viability for how long. From rough observation, my 2 months old seeds have 100% germination but after 6 months germination decreases significantly. Anyway I believe that viability of seeds depend on fertility of mother plant. Healthy adenium seed should have perfect cylinder shape.
Mix : I found that adenium isn't a selective plant. It can grow in many kinds of mix which well drain. Best thing to do is selecting materials that are readily available at your place. I don't have fixed formula for mix. I normally use coarse sand, coconut peat, rice husk and some decomposed leaves. The approximate ratio is 3:2:2:1. I have never use perlite so I can not give any comments on it. I use the mix said for seed germination and seedling. For bigger plants, chips of coconut husk will be added to provide more porosity.
Temperature : I have never experienced too cold weather. Average temperature in Bangkok is always over 25 C so adenium seeds can be germinated all years around. Anyway I suppose that temperature below 15 C can delay or retard germination.
Light & humidity : Fresh adnium seed may germinate over a night. Light is not necessary for germination in first few days. I always put seed tray under table so it gets only indirect sun light. All seeds should germinate in 7 days. Once seed husk fall off seedlings should receive more light. Until they are 2 weeks old, I give them full sun. Anyway mix have to keep humid at all time. I water seedlings once a day or more if temperature is too high. Within one month seedling can be transplants to 4" pot and grow until flowering.
In tropical climate like Bangkok, adenium seedlings grow very fast. Plants should be watered everyday unless it rains or no sun. If seedling is repotted regularly according to its growth, it will flower within less than one year. Fertilizer can be used to accelerate growth rate. I use even formula soluble fertilizer. Fertilizer can be applied with watering every 10 to 15 days.

Adenium seed and its problem
There are two main problems in adenium seed. #1 Seed don’t want to grow, #2 Types of seed doe not meet to our criteria.
There 4 parties should have responsible to the above case: seed farmer, seed trader, seed buyer and adenium it self.
Their involved due to :
1. Wrong in handling seed when harvested
• The way to take care the plant should able guarantee nutrition availability for the seed.
• Seed quality worsens fast as fast as time ticking.
2. Wrong in planting
The way and procedure of planting will impact to life survival of the seed. The good quality of the seeds will be fail if wrong handling in planting
• Planting media is not meeting the life requirement of the seed/plant
• Insufficiency sunlight/weather
3. Genetic Problem
• Genetic of”mother plant” will influence seed quality.
• Mostly Adenium in the market currently is Hybrid. For example: yak siau, thai soco, RCN, brazilian, desert night fork, etc.
• Nowdays rarely we found “true type” of the seed, due to produce the seed will take a long time, minimum 5 generation needed.
4. Fraud and limited knowledge of the seed
The seller sells the seed in obsolescent condition.
The terrible one is when the seller has limited knowledge of the seed, they don’t know which the goods seed and bad seed, how to keep the seed always in good condition after they has had harvest.

How to Plant Adenium Seed
How to plant Adenium Seed
Basically plant adenium seed is easy. Adenium is easily to grow-up. The seed has a bristle that can be flew by the wind to any where.
If you want to be success in planting adenium, the key is use a sterile media with good quality. You can boil the media and spray with fungicide and put it to the sunlight.
Below is the easy way to plant Adenium:
1. Drawn the seed with water +/- 10 minutes.
2. Put media into pot with composition : Fried hull : Coco peat= 1:1
3. Put ¾ media into the pot.
4. Put seed in horizontal position, the distance between the seed is +/- 1 cm. You can put the seed 100-150 pcs in one pot with diameter 20”.
5. Spread the seed with a little bit media (don’t drawn exceed 1 cm)
6. Spray with water smoothly.
7. Cover with transparent plastic and put into a place with low intensity of sunlight.
8. Spray with water everyday. It will take one week the seed will become seedling.
9. After having the leaf, open the plastic, and keep in the shady place and spray with water.
10. After 2 month, remove each seedling to pot. Media composition: Fried hull: volcano sand = 1:1 (add organic fertilizer).
11. Put the plant into a place with medium intensity of sunlight until the plant having age 3 month, and after that you can put it directly to the sunlight.

ABOUT ADENIUM
Adenium was from South Africa, Somalia and Arabic such as Yaman and other places in Middle East. From there, Adenium spread, well known and famous in United States, Thailand, taiwan, Vietnam, India and Indonesia . Adenium was plants from Apocinaceae Sp, that the flowers similiar with Plumeria Sp. flowers. Fook Hui Hwa, that's Taiwaneese call adenium, it means Lucky Flowers. And Chuanchom at Thailand, it means Brings luck and prosperous. Have Adenium at our home will gave courage, motivation, happiness, and luck. Adenium was first time hand polination by Dr.Mark A.Dimmitt, a plant curator from Arizona Desert Museum. In 1985, he hand polination Adenium Obesum with Adenium Swazicum that gave us new hybrid call Adenium Crimson Star. Adeniums have been, till recently, comparatively rare and high value succulents. In part this was because they are somewhat difficult and slow under cool conditions and in part due to the need for cross pollination to set seed. The rather complex floral structure means than hand pollination technique is not obvious.
Thus, in the Western countries, where multiple clones were available, slow growth and closed greenhouses meant little seed set while in tropical Asia, where seed set would have been possible, there was, for a long time there was only one clone- "Singapore"; it set no seed and was propagated by cuttings with its primary use being in landscaping., there was, for a long time only one clone and so no seed set- the cultivar "Singapore" which was propagated by cuttings.
Adenium seed from the wild is usually of poor quality due to pests, poor harvest timing and inadequate processing. Something changed in the late 70's- a little seed became available in Asia.
The huge number of seedlings raised all over the world led to selection of elite clones. Hybridizing between these selections was started in USA, Thailand, Taiwan and India. The story of Adenium breeding in USA is well documented else where.
In Asia breeding and selection efforts were probably most intense in Thailand, where the "bubble" economy meant crazy prices for anything new. The Thai growers imported the best material from USA and Taiwan and worked out a very efficient system of propagation by grafting on seedling Adenium rootstock. Breeding and selection, however, continued in Taiwan, partly because a stronger economy could sustain high prices for new hybrids and partly due to their access to the Chinese mainland market.
From the beginning, three "species" were involved in the breeding- Adenium obesum, A. somalense var. somalense and A. swazicum. Pure white clones and variegates were found and propagated. The Thai's propagated almost anything new including a lot of very mediocre material. Taiwan, all along, concentrated on reds (the Chinese consider both, the Adenium as well as the color red as lucky) since that's where the money was. The newest and best reds still come from Taiwan.
A Taiwanese Adenium nursery, fully under plastic greenhouses. The overall standard of plants is much better in Taiwan but so are the prices.
More recently, the introduction of Adenium somalense var. crispum has added considerable variation to flower color, patterns and form as well as added a certain degree of compactness to its hybrids. Current selections tend to be small flowered and of poor form but that should change. Further crosses using A. s. var. crispum holds tremendous promise for the future.
What lies in the future? There is a lot of new material including some second and third generation crosses using the older A. obesum and A. swazicum hybrids. The discovery of two distinct genetic dwarf lines of A. obesum may lead to a range of ultra compact hybrids.
The current worldwide interest in Adeniums augers well for further efforts with breeding and selection- unless there is money to be made, most growers will stop the breeding effort.
In Europe & USA, Adeniums are just entering what could be called mainstream floriculture. Most of these plants are seedlings.
The market is not only USA and Europe but also Asia- for many cultures, the Adenium is a "lucky" plant. In warm and hot regions, Adeniums, grown to potential, can rival Azaleas in beauty and impact of flowering with much more character to the plant form.

ADENIUM OBESUM
Adenium is a genus of flowering plants in the family Apocynaceae, containing a single species, Adenium obesum, also known as Sabi Star, Kudu or Desert-rose. It is native to tropical and subtropical eastern and southern Africa and Arabia.
Close-up of a flowerIt is an evergreen succulent shrub, growing to 1-3 m in height, with pachycaul stems and a stout, swollen basal caudex. The leaves are spirally arranged, clustered toward the tips of the shoots, simple entire, leathery in texture, 5-15 cm long and 1-8 cm broad. The flowers are tubular, 2-5 cm long, with the outer portion 4-6 cm diameter with five petals, resembling those of other related genera such as Plumeria and Nerium. The flowers tend to red and pink, often with a whitish blush outward of the throat.
Several regional subspecies occur:
Adenium obesum subsp. boehmianum. Namibia, Angola.
Adenium obesum subsp. obesum. Arabia.
Adenium obesum subsp. oleifolium. South Africa, Botswana.
Adenium obesum subsp. socotranum. Socotra.
Adenium obesum subsp. somalense. Eastern Africa.
Adenium obesum subsp. swazicum. Eastern South Africa.
[edit] Cultivation and uses
Adenium is a popular houseplant in temperate regions. It requires a sunny location and a minimum indoor temperature in winter of 10 °C. It thrives on a xeric watering regime as required by cacti. Adenium is typically propagated by seed or stem cuttings. However, only those grown from seed would have the swollen caudex that is prized by collectors.
[edit] Common Names
Due to its resemblance to plumeria, the plant was also called as kalachuchi in the Philippines

Adenium - Desert Rose
Adenium obesum is a genus of spectacular succulents from tropical Africa and Arabia. The species range from shrubs with subterranean or above-ground caudexes to small trees with swollen trunks and stems to 15 feet tall. Their striking forms are further enhanced by some of the showiest flowers of all succulents, often borne in masses over a long season.
Adenium is very popular flower plant in Thailand, Vietnam, Taiwan. You can find some adeniums in Vietnam in the Vietnamese adenium page.
Adenium can be propagated by cuttings or by seeds. It takes about 6 months or longer from seed to flowering. You can make a new hybrid by artificially crossing between 2 different cultivars or different species. The picture of a dissecting adenium flower shows how to pollinate an adenium. Some adenium hybrids can have many branches, some very few. However, branching can be induced by pinching the top. More branches can be induced by treating the wound with lanolin containing BA (Benzyl adenine, 1-2%). However, only a few branches (2-4) will be dominant and become main branches later.

Adenium Socotranum: Tanaman Langka yang Tidak Langka
Menurut ahli2 taxonomi, adenium terbagi atas beberapa spesies. Walau ada yang mengutarakan hanya 1 spesies yaitu obesum dengan beberapa sub spesiesnya tetapi yang kita kenal saat ini mencakup 7 spesies yaitu sp. Obesum, sp. Multiflorum, sp. Oleifolium, sp. Swazicum, sp. Boehmianum, sp. Arabicum dan sp. Socotranum.
Setiap spesies punya beberapa keunikan tersendiri yang membedakan satu dengan yang lainnya baik itu bentuk bunga, warna bunga, bentuk daun, bentuk akar dan lainnya. Karena tanaman adenium ini unik dan menarik dari akar sampai bunga maka kepopulerannya sulit pudar.
Adenium sp. Socotranum
Negara Thailand cukup baik memperkenalkan adenium sp. ini. Sayangnya informasi yang mereka sebarkan tidak 100% benar!. Akibatnya orang saat ini mengira kalau adenium socotranum itu adalah adenium thai soco. Padahal adenium socotranum berbeda dengan adenium thai socotranum!. Negara thailand mengklaim kalau adenium thai soco merupakan pemuliaan adenium socotranum. Di lain pihak adenium socrotanum yang asli semakin sulit dikenali. Karena itulah maka saat ini tidak mudah mencari adenium sp. socrotanum yang asli baik itu di luar negeri sekalipun.
Pulau Socotra: Pulau Kaya Hayati Unik
Asal muasal adenium sp. socotranum adalah pulau Socotra di negara Yaman. Pulau ini juga terkenal dengan beberapa tanaman unik seperti Dorstenia Gigas dan Dracaena cinnabari. Karena pulau ini berada di Jazirah Arab, maka daerahnyapun mirip gurun. Adenium ini banyak tumbuh baik diperbukitan maupun di lembah. Kadang juga ada yang tumbuh di bukit karang yang menghadap ke laut. Lingkungan daerah ini cukup ekstrim walau keliatannya tidak seektrim gurun pasir di arab dan afrika.
Batang kokoh dan Bunga Indah
Menurut referensi online batang adenium ini kokoh dan berbunga indah. Diameter batangnya bisa lebih dari 2 meter sedangkan tingginya bisa mencapai 3 meteran (gambar 1). Untuk bisa mencapai bentuk itu mungkin diperlukan waktu lebih dari 20 tahun. Usia 4 tahun adenium ini baru bisa mencapai diameter bonggol 5cm (gambar 2). Sedangkan waktu berbunga pertama kalinya ada yang harus menunggu 7 tahunan. Perlu kesabaran tinggi menunggu berbunganya adenium ini.
Bentuk bunganya sebenarnya mirip adenium multiflorum, hanya warna merahnya tidak terpusat dipinggir kelopak bunga. Warnanya didominasi pink muda keputihan (gambar 3) yang menyebar merata.
Biasanya adenium ini dapat dikenali dari daunnya yang punya urat berwarna putih menonjol. Saat baru tumbuh daun, warna daunnya coklat keemasan (gambar 4). Bandingkan dengan adenium biasa yang dari pucuk sudah berwarna hijau segar. Warna daun cenderung lebih gelap dan kecoklatan dari adenium jenis lain. Sedangkan batangnya dapat dikenali dari gurat2 garis yang kuat bekas daun yang gugur seperti batang pohon tua. Warna batangnyapun cenderung berwarna coklat keputihan.
Tanaman Langka atau Tidak?
Keseluruhan jenis sp. adenium tidak termasuk dalam kategori tanaman langka. Dalam database cites tidak ditemukan informasi bahwa adenium sp. socotranum masuk dalam kategori tanaman langka dan dilindungi. Tetapi kenyataan di lapangan berkata lain. Adenium sp socotranum sangat sulit dicari di nursery di Indonesia, bahkan bisa dikatakan tidak ada. Kalaupun ada biasanya tidak untuk dijual. Idem ditto di luar negeri. Tapi 1 tahun terakhir ini tampaknya sudah bisa tersedia di luar negeri walau mendapatkannya dengan cara auction atau jumlah sangat terbatas. Soal harga masih dalam range yang belum wajar.
Saat pertama kali ditawarkan adenium ini oleh seorang pemilik nursery, harga yang dipatok cukup besar dan cenderung tidak rasional. Untuk harga yang tinggi itu hanya mendapatkan ukuran adenium setinggi 10cm dengan diameter bonggol 6cm yang katanya berumur 3 tahun. Kondisinyapun tidak terlalu segar karena baru saja pindahan dari luar negeri. Tapi setelah melihat sosoknya dengan baik-baik barulah sadar kalau adenium sp. ini benar2 mengagumkan. Walau kecil, tapi bonggolnya kokoh. Bentuk batangnya kelihatan seperti adenium yang sudah cukup tua.
Tips Merawat
Sebenarnya perawatan adenium ini sama seperti Adenium spesies lainnya. Hanya jangan keburu frustasi karena tidak berbunga2. Kesabaran dalam merawat merupakan kunci agar adenium sp. ini bisa berbunga. Bila anda mengimpornya langsung dari luar negeri baik itu hand carry maupun dikirim, pastikan adeniumnya dalam kondisi sehat saat proses pengiriman. Beri vitamin B1 dan hormon pertumbuhan akar takaran secukupnya saat melakukan proses potting. Jangan diletakkan di tempat yang langsung bersinggungan dengan matahari saat proses adaptasi ini. Setidaknya dibutuhkan waktu 2 minggu sampai satu bulan untuk proses adaptasi ini. Salah satu indikator selesainya proses adaptasi adalah tumbuhnya tunas baru dan kondisi batang yang segar.
Perawatan sehari2 sama saja dengan adenium lainnya. Hanya karena tanaman ini berharga, bisa juga dibuatkan mini greenhouse agar perkembangannya dapat dikendalikan sekaligus aman dari jangkauan tangan jahil. Sebaiknya juga jangan dihujan2kan karena ditakutkan air hujan (khususnya di kota besar) dapat mengurangi imunitas dari adenium ini sehingga bisa timbul penyakit baik dari jamur, bakteri maupun yang lain. Kondisi yang kering dan panas cukup disenangi adenium jenis ini.
Pemberian pupuk berimbang juga diperlukan. Ketika berusia lebih dari 5 tahun (kalau belum berbunga) dapat diberikan pupuk yang memacu pertumbuhan bunga. Pupuk pemacu bunga dapat juga diberikan dibawah usia 5 tahun, hanya saja jangan frustasi kalau bunganya tidak muncul.
Adenium Thai Soco vs Adenium sp. Socotranum
Jadi jangan sampai terkecoh oleh adenium thai soco. Adenium sp. Socotranum sangat berbeda dengan adenium thai soco dari semua sudut. Bahkan harganyapun jauh berbeda, yang mana adenium sp socotranum lebih mahal dari adenium thai soco. Adenium thai soco mudah ditemukan sedangkan adenium sp socotranum sulit ditemukan. Untuk itu jangan sampai tertipu!

Setiap spesies punya beberapa keunikan tersendiri yang membedakan satu dengan yang lainnya baik itu bentuk bunga, warna bunga, bentuk daun, bentuk akar dan lainnya. Karena tanaman adenium ini unik dan menarik dari akar sampai bunga maka kepopulerannya sulit pudar.
Adenium sp. Socotranum
Negara Thailand cukup baik memperkenalkan adenium sp. ini. Sayangnya informasi yang mereka sebarkan tidak 100% benar!. Akibatnya orang saat ini mengira kalau adenium socotranum itu adalah adenium thai soco. Padahal adenium socotranum berbeda dengan adenium thai socotranum!. Negara thailand mengklaim kalau adenium thai soco merupakan pemuliaan adenium socotranum. Di lain pihak adenium socrotanum yang asli semakin sulit dikenali. Karena itulah maka saat ini tidak mudah mencari adenium sp. socrotanum yang asli baik itu di luar negeri sekalipun.
Pulau Socotra: Pulau Kaya Hayati Unik
Asal muasal adenium sp. socotranum adalah pulau Socotra di negara Yaman. Pulau ini juga terkenal dengan beberapa tanaman unik seperti Dorstenia Gigas dan Dracaena cinnabari. Karena pulau ini berada di Jazirah Arab, maka daerahnyapun mirip gurun. Adenium ini banyak tumbuh baik diperbukitan maupun di lembah. Kadang juga ada yang tumbuh di bukit karang yang menghadap ke laut. Lingkungan daerah ini cukup ekstrim walau keliatannya tidak seektrim gurun pasir di arab dan afrika.
Batang kokoh dan Bunga Indah
Menurut referensi online batang adenium ini kokoh dan berbunga indah. Diameter batangnya bisa lebih dari 2 meter sedangkan tingginya bisa mencapai 3 meteran (gambar 1). Untuk bisa mencapai bentuk itu mungkin diperlukan waktu lebih dari 20 tahun. Usia 4 tahun adenium ini baru bisa mencapai diameter bonggol 5cm (gambar 2). Sedangkan waktu berbunga pertama kalinya ada yang harus menunggu 7 tahunan. Perlu kesabaran tinggi menunggu berbunganya adenium ini.

Belajar Menyilang Dari Lebah
Menyilang adenium itu gampang. Begitu ujar Untari Retno Wahyuni, penyilang asal Yogyakarta. Kuncinya, sabar dan rasa cinta pada adenium. Hal itu sudah dibuktikan sendiri oleh Tari - panggilan akrabnya. Ibu berputra tiga ini sukses menyilang adenium setelah belajar dari lebah.
Suatu sore pad a awal tahun 2003, ia mendapati lebah mati terjepit di anther bunga blue hawaii. Itulah yang memberi inspirasi saya bagimana seharusnya penyerbukan adenium. Lantas saya mulai mencari dan mempelajari buku fisiologi tanaman, teknik menyilang dan pemuliaan tanaman, lanjutnya.
Setelah kurang lebih 6 bulan coba-coba menyilang baru berhasil. Penyilangan dilakukan pad a November 2003, antara red dusk (A. obesum) dan Harry Potter (Adenium hybrid) berjalan sukses. Penyilangannya pas hari ulang tahun anak pertama saya, tanggal 1 Nopember. Mulai muncul calon biji tanggal 15, dan panen biji tanggal 11 Februari sebanyak 150 biji, ujarnya.
Semua biji lantas disemai dan hasilnya cukup bagus, 95% berhasil tumbuh. Sembilan bulan berselang, tanaman hasil silangannya mulai berbunga. Corak bunganya perpaduan kedua induk atau nenek-kakeknya. Mekar pertama tanggal 24 Oktober 2004, terangnya.
Tari paling suka hasil silangan Pink Lines dengan Harry Potter, yang diberi nama First Day. Warna dan corak bunganya imut, lucu, dan genit. Soal nama memang saya serahkan ke teman-teman lewat sayembara. Pemenangnya nanti saya kirimi benih dan pupuk, ujarnya. Salah satu silangan paling mengesankan pemilik Omah Ijo Nursery ini juga masih keturunan Harry Potter. Ini merupakan salah satu obsesi saya, kebalikkan dengan corak Harry Portter. Saya ingin bunga merah bergaris putih tegas. Nah, yang ini agak mendekati, tinggal disempurnakan, lanjutnya.
Awalnya, Tari menyukai anggrek. Namun suaminya kurang begitu suka. Pilihan lantas jatuh ke adenium, karena bunganya beraneka warna dan corak. Sosok pohonnya unik dan khas. Paling utama mudah perawatannya dan suasana rumah tidak lembap dan gelap, karena pohon ini suka sinar matahari, ujarnya, pertama mengenal adenium pada awal 2003. Koleksi pertamanya, blue hawaii berkelir ungu dan berbunga lebat, dari Godongijo Nursery.
Trik Menyilang Adenium Ala Tari
Tujuan seleksi harus jelas. Ingin menghasilkan bunga, bonggol, jenis daun, pertumbuhan atau sifat lainnya. Rasional dalam menentukan kriteria seleksi. Cari informasi tentang sejarah jenis atau bunga indukan. Kumpulkan materi genetik sebanyak yang kita bisa. Banyak belajar dari buku, jurnal, majalah, tabloid, atau orang yang lebih tahu, saran Tari.
Menyilang adenium itu gampang, yang susah menentukan indukan yang sesuai. Soalnya bunga adenium mempunyai sifat incompabilitas yang tinggi dan self sterile. ujarnya. Bunga adenium tergolong penyerbuk bersilang. Jadi. sebenarnya semua bijinya adalah hibrida. Beberapa spesies atau varietas sering tidak bersesuaian alias saling menolak. Ada juga adenium yang putiknya (stigma) tidak berfungsi secara baik, dan beberapa lainnya tidak menghasilkan pollen.
Berdasar pengalaman Tari, spesies Adenium swazicum dan turunannya tidak dapat dipakai sebagai indukan betina. Soalnya stigma tidak berfungsi sebagaimana mestinya. Kalaupun terbentuk calon biji, perkembangannya tidak begitu baik. Demikian juga penyilangan antara A. obesum dengan A. arabicum sangat sulit dilakukan. Namun anehnya kalau arah persilangan dibalik, A. arabicum dengan A. obesum kemungkinan diperoleh biji jauh lebih mudah.
