We refer to this plant as Bridelia ovata (variegated) but we have no reliable sources to verify the name.
I planted them under a rain tree and it received the morning sun only. Thus far, it has been doing well and did not lose much of its variegation under the subdued light condition below the tree's canopy.
To me, the pinkish new leaves are the main draw. As it ages, they turn white before the final green. Sometimes, I let my imagination run wild and I imagine the pink flushes to be butterflies perching on the plant.
