Hi, folks! About seeds, once again, it's a gamble. I bought seeds that were from both parents being double, and only about 15% are double. This was agreed to by a lot of seed growers on the Yahoo Adenium discussion group.
If you buy either red or white seeds from adenium_ko, on Ebay, you will most likely get those colors, rather than pink.
Just don't expect too much from seeds, and wowee, they take a year or longer to bloom.
