Thanks
@Rainbow. Those two I did buy from Adenium ko on eBay.
Welcome
@SCButtercup. I think there are a lot of places to buy seeds. I did look at Adenium center, but they only sell seeds at a large quantity, and I do not want 100 seeds of 1 type.
I did buy mainly on eBay. For instance Adenium ko from Taiwan. Has a lot of difference colors and types at a good price.
As for double or single flower. I guess that is just a Mather of taste. I am more for the single, but I do not think that it does make a difference in the caring.
