Wowee, if you want Adenium culture tips, try
http://siamadenium.com/
Takes forever to load the page, but it's worth it. The fellow changes the site constantly, it's never ever the same, yet you can find the articles you want. I have learned so much here, !!as well as on Adeniums India!!. Not to be contradicting, just adding to what Mike says.
Right now, the page starts with the breeding of a black double, then goes on to grafting a single bud, then multiple grafts onto onr 'bottom' plant. Then planting seed, then breeding, then a couple of other types of flowers, miniature roses, water lillies, then back to Adeniums, with different sizes, yellows, and hahahaha he cannot get an orange!! and then other flowers, please, no, they have a brown, UGH!!!
Not quite half way down the page is a mind boggling photo of a ten acre, or maybe twenty acre field of adeniums. Says 30,000 plants. You can hire people in Thailand for $4 a day.
Oh. fooey, I was reading a page, clicked the photo, and should have punched my computer's 'back' button. I closed the page. Owell, good for you, I'm ranting!
And then there are the bonsais and how to arrange roots.
OK, I'll stop. Both of these growers are on facebook. Hmm, a flower for you---
