Thanks Becky and Maurice!
Maurice, I would be greatly indebted and profoundly happy to have as excruciatingly exact instructions and/or pointers you'd be willing to give, even where to economically purchase whatever would be needed to try your idea out. And, in particular, I find myself wondering where to cut the nascent roots at (picture? I'd hate to cut to high or low, if it ruins the seedling). Would the roots need occasional re-trimming to keep them from growing, or is it okay if they grow (just not necessary)?
I always think its far more valuable to post such information here so that others can come across it, reference it in the future, etc. So, if you are willing, please do so in this thread!
Two years ago I came under the spell of a photo that, I think, is of a regular lily bloom that, while not an albino plant, seemed to produce an albino bloom. It really jump-started my journey just to have a visual of what might be a similarly resulting flower ... so if I could keep trying now with safe materials, I'd really enjoy it!
