I found a photo but no further information here https://kwitkaman.com/gallery/radermachera-sinica-variegata/

its also mentioned here https://www.arthurleej.com/p-o-m-April11.html”A yellowish-green variegated cultivar promoted as "Crystal Doll" since 1995 if not before, is slightly smaller. This is likely also called 'Kaprima' --since at least 1992.”

Variegation shouldn't affect the care much. So just follow recommendations for Radermachera sinica.

agree ..... same care as the green version ...

the only caveat is that white tissue can burn in too much sun.. especially if water is not perfected ....

it may grow itself into sun.. and those leaves would be much more tolerant.. but again.. if it goes dry in a pot.. it might burn ..
