What is a variegated plant? / Get back the variegation from reverted plant!
This is where tiny air pockets are present between the pigmented lower cell layer and the non-pigmented upper cell layer. This makes a patch of transparency that reflects light and gives a shiny or silver look. It can cover the entire leaf, or be patchy.
How to check variegation of node
A variegated node needs to have variegation present in the stem as well as the leaves. Lightly variegated leaves attached to a fully green stem are unlikely to ever produce strongly variegated growth.
Propagation
Each node has 2 types of growth points. Either the same side with the leaves or the opposite side of the leaves. Depending on where it pops up new buds.
Propagate by cutting the top part of the plant that has a pattern of variegation, make sure that new leaves are still on their way to unfurling, or even safer, This is done so that the new leaf will continue to unfurl normally and the cycle for new leaves is still on track. There will be no dormant nor delay for the new leaves to come out.
Some variegated plants will revert to their original color but cutting from variegated node plants has a higher percent to become variegated than normal node plants.
Why do plants lose variegation?
Variegated plants either fall under stable or unstable due to their ability to revert to their natural solid green state. Thus, plants lose variegation when they change to their natural, green coloring. Stable variegated plants refer to cultivars that remain variegated and do not revert to their solid green coloring; whereas, unstable variegated plants can revert to a solid green leaf. Variegation reverts for varying reasons; however, plants commonly revert to a solid green state to better capture sunlight for photosynthesis, as chlorophyll helps absorb light.
