@jericson22, I apologize, but I took the liberty of downloading and cropping your photos to highlight your variegated Adenium seedling. Here are the two photos, with the oldest first:
I hope this grows into a nice plant for you! It certainly is looking much better now it's developing more chlorophyll.
I currently have five 9-month old seed-grown variegated specimens split between seed from two different pod parents [purchased from Ko of Taiwan]. Here is the largest, my favorite:
It's running smaller than it's fully green siblings due to the reduced chlorophyll, but better than the other four variegated ones. The second two are doing relatively well, but much smaller as they have less chlorophyll. I think the biggest difference is that with the first one the newest tiny leaves already have some chlorophyll, while in the other four the newest leaves are pink/white and develop much more slowly. The leaves with little or no chlorophyll are also more subject to rot.
Here are the next two, very similar to each other but one from each of the two seed packs:
The last two are really struggling. They can't seem to keep leaves long enough to grow, so at nine months are still less than two inches tall with hardly any leaves at all. They keep hanging in there so I haven't given up on them yet!
I may move the last two into a shadier position, as it seemed the variegated plants had more chlorophyll when they received more shade. At least, in the mass planting, the variegated seedlings started really growing and coming into their own when their siblings began to tower over them. Maybe it was just coincidence, but what have I got to lose by experimenting? As it is, it's primarily the chlorophyll in the caudex that's keeping them alive.
