hari,
Sorry for us not seeing this Hari. I follow the Adenium forum and do not watch this forum.
Does this tree have reddish colored leaves? It is hard to tell in photo and I see white marks on the leaves. Is this dried up marks or white variegation on the leaves?
My first thought was an Adenium called "Nila Kan" which has reddish tones to the leaves. More so to the new leaves. With this tree, the flowers are red and they most often are not fully formed blooms.
Sometimes they are.
This tree was one from a gentleman in Florida that had sprayed a row of weeds on the ground with a weed killer and it got on many of the plants. One in particular did come back and it regrew with reddish leaves. Since then this tree has been propagated by grafting and is quite well spread throught out North America and most of Asia. That of course, if it is Nila Kan.
