Thanks for the suggestion, Beverly. 'Grand Canyon' has undulating leaves whereas this one only has one leaf that shows undulations, but that may be a sign of immaturity. We'll see how it develops and it may well prove to be GC, time will tell. Thanks again.

Are there 2 plants in there? Or multiple divisions of one plant?

Could the variegation take a few weeks to develop, like for the Piedmont Gold sports?

Sum Substance, ??

There is one plant. There is nothing I could find for 'Titanic' to indicate the variegation was slow to develop and it certainly isn't 'Sum and Substance'. I'm tending to go with Beverly's suggestion of 'Grand Canyon', 'Sum and Substance' has a much rounder leaf and the friend who gave it to me came by last night and showed me another leaf from the section she kept back and it showed the undulations you see on only a couple of leaves in the pictures that would appear to be characteristic of GC.

Thanks again to all who contributed!
